Keeping Standards up-to-date
Standards are living documents which reflect progress in science, technology and
systems. To maintain their currency, all Standards are periodically reviewed, and
new editions are published. Between editions, amendments may be issued.
Standards may also be withdrawn. It is important that readers assure themselves
they are using a current Standard, which should include any amendments which
may have been published since the Standard was purchased.
Detailed information about joint Australian/New Zealand Standards can be found by
visiting the Standards Web Shop at www.standards.com.au or Standards New
Zealand web site at www.standards.co.nz and looking up the relevant Standard in
the on-line catalogue.
Alternatively, both organizations publish an annual printed Catalogue with full
details of all current Standards. For more frequent listings or notification of
revisions, amendments and withdrawals, Standards Australia and Standards New
Zealand offer a number of update options. For information about these services,
users should contact their respective national Standards organization.
We also welcome suggestions for improvement in our Standards, and especially
encourage readers to notify us immediately of any apparent inaccuracies or
ambiguities. Please address your comments to the Chief Executive of either
Standards Australia or Standards New Zealand at the address shown on the back
cover.

PREFACE
This Standard was prepared by the Joint Standards Australia/Standards New Zealand
Committee PL-006, Polyolefin Pipe Systems, to supersede, in part, AS 2492—1994, Cross-
linked polyethylene (PE-X) pipe for hot and cold water applications, which is withdrawn.
The objective of this Standard is to provide a standard specification for manufacturers and
purchasers of cross-linked polyethylene pipes to be used in pressure applications.
The objective of this revision is to revise the Australian Standard and issue it as a joint
Australian/New Zealand Standard. This revision extends the product applications to general
pressure, including fuel gas, and includes sizes up to DN 1000.
This Standard is based on the latest ISO documents for gas and water applications and,
where appropriate, the principles of AS/NZS 4130 Polyethylene (PE) pipes for pressure
applications and AS/NZS 4131, Polyethylene (PE) compounds for pressure pipes and
fittings have been followed. One exception is the inclusion of the optional addition of
pigment or carbon black masterbatch during extrusion. Appendix A incorporates increased
BRT frequency related to use of the option.
The overall service (design) coefficient of 1.25, taken from ISO 12162, Thermoplastics
materials for pipes and fittings for pressure applications—Classification and designation—
Overall service (design) coefficient, has been applied to establish the hydrostatic design
stress.
The requirements for resistance to slow crack growth and rapid crack propagation are
intended to facilitate the use of PE-X pipes for fuel gas at pressures up to 16 bar and for
general pressure applications without special granular bedding.
The means for demonstrating compliance with this Standard (Appendix A) have been
included for minimum sampling and testing frequency plans to include batch release tests,
process verification tests and type tests requirements, to simplify and improve product
quality verification.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the
application of the appendix to which they apply. A ‘normative’ appendix is an integral part
of a Standard, whereas an ‘informative’ appendix is only for information and guidance.
Statements expressed in mandatory terms in notes to tables and figures are deemed to be
requirements of this Standard.
Notes to text contain information and guidance. They are not an integral part of the
Standard.

FOREWORD
This Standard describes pipes in terms of dimensional requirements, PE-X material, and
PN rating.
Appendix B tabulates operating parameters for PE-X pipes when used for the conveyance of
hot and cold water within buildings. These parameters are taken from ISO 15875-2, Plastics
piping systems for hot and cold water installations—Crosslinked polyethylene
(PE-X), Part 2: Pipes, along with the pressure test requirements for PE-X 80. Other test
requirements are taken from ISO 14531-1, Plastics pipes and fittings—Crosslinked
polyethylene (PE-X) pipe systems for the conveyance of gaseous fuels—Metric series—
Specifications, Part 1: Pipes.
In this Standard, there is a partial pressure limitation for liquefied petroleum gas (LPG).
The aim of this limitation is to prevent the formation of aliphatic hydrocarbon liquids under
normal service conditions and subsequent deleterious effects on the long-term performance
of the pipe. At a partial pressure of 300 kPa absolute, the dewpoint for a typical propane
LPG is below 0°C. The designer of a cross-linked polyethylene reticulation system should
be aware that if service temperatures lower than this are likely to occur or if LPG
containing significant quantities of butane gases are to be reticulated, the partial pressure
limitation must be revised to avoid condensation of hydrocarbon liquids.

Cross-linked polyethylene (PE-X) pipes for pressure applications
S E C T I O N 1 S C O P E A N D G E N E R A L
1.1 SCOPE
This Standard specifies requirements for cross-linked polyethylene pipes for the
conveyance of fluids under pressure. Such fluids include, but are not restricted to, water,
wastewater, slurries, compressed air, and fuel gas. Fuel gas includes natural gas, liquefied
petroleum gas (LPG) in the vapour phase and LPG/air mixtures. The partial pressure of the
LPG is not to exceed 300 kPa absolute.
Pipes intended for the transmission of fuel gas are hereinafter referred to as ‘gas pipes’ and
are not be operated at pressures above 1600 kPa gauge.
1.2 MEANS FOR DEMONSTRATING COMPLIANCE
Compliance with this Standard shall be demonstrated in accordance with Appendix A.
1.3 APPLICATION
This Standard does not apply to gas pipes for use with petroleum liquids, including liquid
LPG and liquid pentane, or with manufactured or mixed gas distribution systems, which
may contain more than 1% aromatics by volume, unless resistance to aromatic constituents
has been demonstrated, as required in Clause 2.3.
Pipes that do not contain carbon black in compliance with this Standard are not intended for
extended exposure in direct sunlight.
PE-X pipe is suitable for use at temperatures up to 100°C as described in Appendix B;
however, continuous long-term operation should be between −50°C and +70°C.
The test requirements specified in this Standard may be achieved by alternative test
methods if such methods can be shown to provide equal or greater accuracy than those
specified herein. In all cases of dispute, the methods specified in this Standard shall be
considered the reference test methods.
1.4 REFERENCED DOCUMENTS
The documents referred to in this Standard are listed in Appendix C:

2.1 BASE MATERIAL
2.1.1 General
Base material used in the manufacture of pipes, which meets the performance requirements
described in Clause 2.3, shall be cross-linked by the peroxide (PE-Xa), silane (PE-Xb) or
electron beam (PE-Xc) cross-linking process or, subject to consultation with the pipeline
operator, by another process.
The base material shall be fully compounded prior to extrusion, with the exception of–
(a) those additions necessary for the acceleration of cross-linking;
(b) the optional addition of pigment or carbon black masterbatch; and
(c) PE-Xa, where all materials are blended in powder form prior to extrusion.
The addition of pigment or carbon black masterbatch during extrusion shall not be an option
for cross-linkable pipes, i.e., those that achieve the degree of cross-linking during or after
installation.
2.1.2 Carbon black
When determined in accordance with ISO 6964, black polyethylene compounds shall
contain 2.25 ± 0.25% by mass of carbon black.
When determined in accordance with ASTM D3849 or equivalent, the average particle size
of carbon black shall be in the range of 10 to 25 nm.
When determined in accordance with AS/NZS 1462.27, the toluene extract of carbon black
shall be not greater than 0.1%.
NOTE: Type P carbon blacks are known to be capable of meeting this requirement.
2.2 TECHNICAL FILE
The manufacturer of the pipe shall maintain the availability of a technical file (generally
confidential) with all relevant material data to prove the conformity of pipes to this
Standard. It shall include all the results of type testing. Any change in the materials used,
which is likely to affect the product quality and performance, shall require a reassessment
of material performance against the requirements of this Standard.
2.3 PERFORMANCE
PE-X shall conform to the performance requirements given in Tables 1 and 2 when tested in
the form of pipe. Conformity shall be demonstrated by the pipe manufacturer and shall
relate to one source of base material and associated pipe manufacturing method.
2.4 MATERIAL CLASSIFICATION
2.4.1 General
Classification testing and evaluation shall be undertaken in accordance with ISO 1167 (or
AS 1462.6), ISO 12162, and ISO 9080 (or AS/NZS 1462.29), plus specific additional
requirements for PE-X 80 detailed in Clause 2.4.3.

2.4.2 Predictive relationship
The test data generated (pipe stress applied and failure time), covering the temperature
range 20°C to 100°C, shall be used to derive the following predictive relationship between
the long-term hydrostatic strength (σLTHS
), failure time and temperature:
logt = A + BlogσLTHS
/θ + C/θ + DlogσLTHS
. . . E(1)
where
θ = temperature, in Kelvin
t = time, in hours
σL = long-term hydrostatic strength, in megapascals
A, B, C, and D are coefficients determined from experimental data.
The relationships between time, stress and temperature thus derived shall be used to obtain
the value of one unknown when the other two variables are known.
2.4.3 Additional requirements for PE-X 80
For PE-X 80 pipes, the values of A, B, C, and D obtained from testing and evaluation in
accordance with ISO 9080 or AS/NZS 1462.29 shall be −105.8618, −18506.15, 57895.49,
and −24.7997 respectively, or other values that yield higher stress.
NOTE: Appendix B provides specific examples of operating conditions for PE-X 80 pipes.
2.4.4 Provisional qualification
Prior to establishment of classification, provisional qualification as PE-X 80 may be
afforded to products that meet the 1000 h, 95°C hydrostatic strength requirements for
PE-X 100 (see Note). Similarly, provisional qualification may be afforded to PE-X 100
products that meet the 1000 h, 95°C hydrostatic strength requirements for PE-X 125.
However, provisional qualification shall not be afforded to PE-X 125 products.
NOTE: Mechanical properties of pipes are specified in Table 3.3.

3.1 FREEDOM FROM DEFECTS
3.1.1 General
Defects shall not affect the performance or function of the pipe in service. Pipes shall not
have any blisters, voids, burnt particles or heat marks. When grooves, wrinkles, rippling,
dents or projections are present, the pipe shall comply with the dimensional requirements of
Table 3.1. Where defects are present and the product is submitted for acceptance, the
manufacturer shall be able to demonstrate its conformance to this Standard.
The defects described above cannot be completely quantified. Where the presence, size or
frequency of any of these are considered to be of concern, arrangements should be made
between the purchaser/approving authority/certifying body (as appropriate), and the
manufacturer. This may be achieved by the provision of acceptable type samples or
methods of test.
3.1.2 Pipe ends
Pipe ends shall not have any chips, burrs or rough edges and shall be nominally square.
3.1.3 Cleanliness
Pipes shall be internally clean and free from swarf and other manufacturing debris.
3.2 EFFECT ON FLUID OTHER THAN WATER AND FUEL GAS
Where fluids other than water and fuel gas are to be conveyed, the effect on the fluid shall
be established by reference to the pipe manufacturer.
3.3 EFFECT ON WATER
This Clause is not applicable to pipes intended for conveyance of fuel gas.
Blue and purple pipes shall comply with AS/NZS 4020 with a scaling factor of 1.
3.4 COLOUR
3.4.1 General

3.4.4 Purple (recycled water)
The colour of purple pipes, stripes and jackets shall be purple neither lighter than
RAL 310 70 15, nor darker than RAL 330 40 40 or RAL 310 50 30.
3.5 NUMBER AND COVERAGE OF STRIPES (IF ANY)
Striped pipes shall have a minimum number of four stripes.
For pipes DN <280, not less than 15% of the external pipe surface shall be covered by the
striping material.
For pipes DN ≥280 and DN <630, the percentage coverage shall be not less than 10% of the
external pipe surface.
For pipes DN ≥630, the coverage shall be not less than 8% of the external pipe surface.
3.6 OPACITY
Pipes for drinking water based applications shall not transmit more than 0.2% of visible
light when tested in accordance with ISO 7686.
3.7 PRESSURE CLASSIFICATION
Pipes for applications other than gas are classified in terms of the nominal pressure rating
(PN) at material service temperature of 20°C, as follows:
PN 8 Nominal working pressure of 0.80 MPa
PN 10 Nominal working pressure of 1.00 MPa
PN 12.5 Nominal working pressure of 1.25 MPa
PN 16 Nominal working pressure of 1.60 MPa
PN 20 Nominal working pressure of 2.00 MPa
PN 25 Nominal working pressure of 2.50 MPa
Pipes for gas applications are classified according to SDR.
Standard dimension ratios for pipes made from PE-X 80, PE-X 100, and PE-X 125
compounds are given in Table 3.2.
3.8 DIMENSIONS
3.8.1 Diameter and wall thickness
The thickness at any point shall not fall below the minimum specified in Table 3, as
appropriate to the DN and SDR, and the average thickness shall not exceed the maximum
specified. When measured at a distance not less than 5% of DN from the cut end of the
pipe, in accordance with AS/NZS 1462.1, the mean outside diameter (Dm
) shall comply
with the requirements of Tables 3.1(A), 3.1(B) and 3.1(C).
3.8.2 Coiled pipe
The internal diameter for a coil of pipe shall be such that kinking is prevented.
3.8.3 Out of roundness
Ovality requirements shall apply at the time of manufacture and before coiling.
3.9 MECHANICAL PROPERTIES
Pipes shall conform to the mechanical performance requirements given in Table 3.3.

NOTES:
1 Conducting tests at 20°C for 100 h at a stress level agreed between the manufacturer and pipeline
operator is permissible if correlation with 1000 h data can be demonstrated.
2 For pipes of dn≥90 mm. Testing is only required for gas pipes and when the wall thickness of the pipe is
greater than the wall thickness of the pipe used in the rapid crack propagation test on the PE-X compound
(see Note to Table 2.1). Tests shall be carried out on the thickest walled pipe in the manufacturer’s range.
For large diameter thick walled pipe, ISO 13478 may be used.
3 Alternative temperatures of −20°C or −35°C may be used to qualify material for minimum operating
temperatures higher than −50°C.
4 For pipes of en >6 mm, for quality control, conducting tests for 165 h at 95°C and a pressure agreed
between the manufacturer and pipeline operator is permissible if correlation with 80°C data can be
demonstrated.
5 The test pressures stated are for SDR 11 pipes. Guidance regarding test pressures for pipes of other SDR
values is given in ISO 13479.

APPENDIX A
MEANS FOR DEMONSTRATING COMPLIANCE WITH THIS STANDARD
(Normative)
A1 SCOPE
This Appendix sets out two means by which compliance with this has to be demonstrated by
a manufacturer as follows:
(a) The use of a product certification scheme.
(b) The use of a minimum sampling and testing frequency plan.
A2 RELEVANCE
The long-term performance of pipeline systems is critical to the operating efficiency of
water and gas agencies in terms of operating licences and customer contracts. The long-
term performance of plumbing systems is similarly critical to the durability of building
infrastructure, protection of public health and safety and protection of the environment.
A3 DEFINITIONS
A3.1 Acceptable quality level (AQL)
When a continuous series of lots or batches is considered, the quality level which, for the
purpose of sampling inspection, is the limit of a satisfactory process average
(see AS 1199.1).
NOTE: The designation of an AQL does not imply that a manufacturer has the right knowingly to
supply any non-conforming unit of product.
A3.2 Batch
Schedule of pipes, all of the same nominal diameter, wall thickness and marking,
manufactured from the same material or compound on the same machine.
NOTE: The batch is defined and identified by the pipe manufacturer.
A3.3 Batch release test (BRT)
A test performed on a sample from the batch or lot, to confirm conformance to the
requirements of this Standard before the batch can be released.
A3.4 Inspection level
The relationship between the batch or lot size and the sample size (see AS 1199.1).
A3.5 Lot
A clearly identifiable subdivision of a batch for inspection purposes.
A3.6 New material formulation
Any of the following changes:
(a) Change of polymer, that is—
(i) change of supplier,
(ii) change of polymerization, or
(iii) change of chemical properties of comonomers.

(b) Change of additive package (e.g. pigments, antioxidants), that is—
(i) change of amount greater than ± 30% of individual additive;
(ii) change of chemical properties; or
(iii) change of nature of additive.
A3.7 Process verification test (PVT)
A test performed on a sample at specific intervals, to confirm conformance to the
requirements of this Standard before further batches can be released.
A3.8 Sample
One or more units of product drawn from a batch or lot, selected at random without regard
to quality.
NOTE: The number of units of product in the sample is the sample size.
A3.9 Sampling plan
A specific plan that gives the number of samples and the frequency of inspection or testing.
A3.10 Type test (TT)
A test performed on a sample to confirm conformance to the requirements of this Standard
before any batches can be released.
A4 PRODUCT CERTIFICATION
The purpose of product certification is to provide independent assurance of the claim by the
manufacturer that products comply with this Standard.
The certification scheme shall meet the criteria described in SA HB 18.28/SANZ HB 18.28
(ISO/IEC Guide 28) in that, as well as full type testing from independently sampled
production and subsequent verification of conformance, it requires the manufacturer to
maintain effective planning to control production.
The certification scheme serves to indicate that the products consistently conform to the
requirements of this Standard.
Product certification shall be conducted by a certification body accredited by the Joint
Accreditation System for Australia and New Zealand (JAS-ANZ) or by another certification
body that is acceptable to JAS-ANZ.
The frequency of the sampling and testing plan, as detailed in Paragraph A5, shall be used
by the certifying body for product compliance auditing. However, where the manufacturer
can demonstrate adequate process control to the certifying body, the frequency of sampling
and testing nominated in the manufacturer’s quality and/or documented procedures shall
take precedence for the purpose of product certification.
A5 MINIMUM SAMPLING AND TESTING FREQUENCY PLAN
A5.1 General
Table A1 sets out the minimum sampling and testing frequency plan for a manufacturer to
demonstrate compliance of product(s) to this Standard.

A5.2 Retesting
In the event of a test failure, the products manufactured since the previous test(s)
conforming to the requirements outlined in Table A1 shall be quarantined as a batch. A
further set of samples shall be selected randomly from the quarantined batch using a
sampling plan to AS 1199.1 for an acceptable quality level (AQL) of 2.5 and an inspection
level of S3, unless otherwise specified. If the retest requirements are met, the batch may be
released and compliance with this Standard for the quarantined batch may be claimed.
Should a failure occur on retesting, then the quarantined batch shall be rejected and claims
and/or marking indicating compliance to this Standard shall be suspended until the cause of
the failure has been identified and corrected.
A5.3 Rejection after test
In the event of a quarantined batch being rejected after retesting in accordance with the
procedures set out in Paragraph A5.2, it may be subjected to 100% testing for the failed
requirement(s), and only those items found to comply may be claimed and/or marked as
complying with this Standard.

APPENDIX B
OPERATING CONDITIONS FOR PE-X 80 PIPES USED FOR CONVEYANCE OF
HOT AND COLD WATER WITHIN BUILDINGS
(Informative)
This Appendix provides data derived from ISO 15875 in order to facilitate selection of
appropriate pipe for the application.
For continuous service temperature of 20°C, design stress is 7.6 Mpa; for 60°C, design
stress is 4.75 Mpa; and for 70°C, design stress is 4.26 MPa.
For continuous service temperatures in excess of 70°C, life beyond 50 years should not be
assumed; however, brief excursions to temperatures up to 100°C may be permissible.
For example, ISO 15875-1 provides for 49 years at 70°C, plus one year at 80°C, plus 100 h
at 95°C.
For particular circumstances, reference should be made to the manufacturer.
A design based on the maximum operating temperature is regarded as conservative and an
advantage may be gained from an analysis that incorporates Miner’s Rule (ISO 13760).

Standards Australia
Standards Australia is an independent company, limited by guarantee, which prepares and publishes
most of the voluntary technical and commercial standards used in Australia. These standards are
developed through an open process of consultation and consensus, in which all interested parties are
invited to participate. Through a Memorandum of Understanding with the Commonwealth
government, Standards Australia is recognized as Australia’s peak national standards body.
Standards New Zealand
The first national Standards organization was created in New Zealand in 1932. The Standards
Council of New Zealand is the national authority responsible for the production of Standards.
Standards New Zealand is the trading arm of the Standards Council established under the Standards
Act 1988.
Australian/New Zealand Standards
Under a Memorandum of Understanding between Standards Australia and Standards New Zealand,
Australian/New Zealand Standards are prepared by committees of experts from industry,
governments, consumers and other sectors. The requirements or recommendations contained
in published Standards are a consensus of the views of representative interests and also take
account of comments received from other sources. They reflect the latest scientific and industry
experience. Australian/New Zealand Standards are kept under continuous review after publication
and are updated regularly to take account of changing technology.
International Involvement
Standards Australia and Standards New Zealand are responsible for ensuring that the Australian
and New Zealand viewpoints are considered in the formulation of international Standards and that
the latest international experience is incorporated in national and Joint Standards. This role is vital
in assisting local industry to compete in international markets. Both organizations are the national
members of ISO (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission).
