Common ground between Legislation

• European manufacturers are required to provide certified products to

comply with EN12101-3: Smoke and heat control systems.

Specification for powered smoke and heat exhaust ventilators.

• International Manufacturers are required to provide compliant

products to ISO 21927-3: Smoke and heat control systems - Part

3: Specification for powered smoke and heat exhaust

ventilators.

• Israel Manufacturers will be required to provide compliant products to

SI 1001 Part 7: Fire Safety in Buildings: Smoke and control

systems – Powered smoke and heat exhaust ventilators.EN12101-3, ISO 21927-3 and SI 1001 Pt7 are essentially based upon similar legislation requirements .

Background to the Legislation

• The Kings Cross fire (1987), and the resulting regulatory changes

within the UK gave the subject of smoke control and emergency

tunnel ventilation visibility, and directly drove industrial fan

manufacturers product development.

• Further disasters in Europe, including but not limited to Mont Blanc

and Tauern, have raised the profile of smoke control and emergency

tunnel ventilation in Europe.

• European Union member states have taken action, Council Directive

89/106/EEC and Harmonised Product Standards are superseding

national regulations relating to emergency smoke ventilation.

• In 1992 the European Single Market was created. The objective

was to remove barriers to trade through the European Economic

Area.

• New Approach Directives are intended to place control on product

design, with the principle objective being to provide a “level playing

field” for product safety requirements across the European

Community.

• The primary function of New Approach Directives is to ensure

that products are sufficiently well designed and built, and that

they are fit for the purpose which they are sold.

The European Single Market & Directives

The same principle applies to the Israel Market – the implementing of

SI 1001 Part 7 will ensure all manufacturers (local or not) will

operate on a level playing field.

• In compliance with EN12101-3 the visible manifestation of

compliance with the construction product directive is the appearance

of the CE logo on the product which contains:

0123

Any Co Limited, P.O. Box21, B-1050 00

0123 - CPD - 001 EN 12101-3 Powered smoke and heat exhaust ventilators for use in Construction Works Response delay 30 s at SL 125 Resistance to Fire class F200 Motor rating Class B/Class F

— identification number of the notified body— the name or identifying mark of the producer/supplier, and— the last two digits of the year in which the marking was affixed, and— the appropriate number of the EC-certificate of conformity, and— the number of this standard (EN 12101-3), and— type of product (powered ventilator), and— response delay (s), and— fire resistance class— Motor rating

Identification & Labelling: The CE Mark

It should be noted, although EN12101-3 is the basis for ISO 21927-3

standard (and therefore SI 1001-Pt7), there is no requirement in ISO

or SI for CE Marking or display compliancy labels on products*.

*Although existing Israel marking “Tav Teken” labeling will likely remain, its not required by the standard

• The Construction Product Directive (CPD) is Council Directive

89/106/EEC of 21st December 1988 relating to construction products.

• The directive lays down essential performance criteria under six

general headings, including safety in case of fire.

• Performance requirements apply to the products as a whole, not

simply to each individual components (very important for HT fans)

1.Blades / Impellers

2.Motor

3.Casing

The Construction Products Directive

• Smoke control products are identified as having a critical role to

play in the event of a fire related emergency.

• EN12101-3: Smoke control fans are subject to approval based on

independent assessment of their performance and the on-going

control of their manufacture.

• EN12101-3: Test houses able to perform the independent

assessment are “notified” to the European Commission and all

governments within the EU are bound to accept their test results.

Conformity With the C P D

There is no third party testing requirement in ISO

21927-3 standard (and therefore SI 1001-Pt7).

Non-EU Manufacturers can self certify compliance to

the ISO & SI standards – EU Manufactures must

obtain EN12101-3 to comply.

The Harmonised Standard EN13501-4

• The standard EN 13501-4 ‘Fire classification of construction products

and building elements – Part 4: classification using data from fire

resistance tests on components of smoke control systems” supports

essential requirements of the construction product directive.

• EN 13501-4 supports the construction product directive by defining a

harmonised procedure for the classification for resistance of fire of

construction products.

• It interprets the functional requirements for the different groups of

building products and explains the method for deriving their

classification on the basis of test results for individual products.


The classifications derived for powered smoke and heat exhaust ventilators

within EN 13501-4 are:

• F200 A constant temperature of 200C for 120 minutes.

A constant temperature of 250C for 120 minutes


• F400 A constant temperature of 400C for 90 or 120 minutes.

• F600 A constant temperature of 600C for 60 minutes


Original Israel requirements of 250C for 2 hours*, although not an

official temperature classification class, would have been

considered as F300 or 300C for 2 hours.*Not operating under temperature rated airflow conditions.

SI 1001 – Part 7

ISO 21927-3


EN 12101-3

Testing, Approving & Certifying a Range

• The standard provides a procedure for approving a range of fans.

• Rules allow the approved range to include scaled diameters from

0.63 to 1.26 of those tested.

EN 12101-3, ISO 29127-3 & SI 1001-Part 7 Product Approval

EN 12101-3 Product Range Testing Requirements

Tested Fans to cover full Product Range TestApproved Sizes covered by tested fans

Clauses & additional requirements needed to certify the range.


EN 12101-3, ISO 29127-3 & SI 1001-Part 7 - Annex A States:

• At least two fans must be tested at their highest rotational speed.

• The fan with the most highly stressed impeller must be tested.

• Fans powered by motors with the smallest and largest frame sizes at

their highest output must be tested.

• The fan must be set up for test in a way that represents the

conditions to which it is exposed in service. (Horizontal, Vertical,

F200, F300, F400, insulated, non-insulated etc.)



• Range certification may be obtained by defining a product range, and

then conducting a series of type-tests that comply with the

requirements for range certification.

• A draw back of range certification is the difficulty associated with

modification of the design to accommodate a client request, or

improve the product. As such range certification might be a block to

product development.

• Single product certification may only be obtained, by manufacturing

and testing an additional fan to that being sold.


• Testing large tunnel fans requires a notified test house that can carry

out the test.

• At the time of writing, only a minority of test house are able to test

fans over 1.6 meters in diameter

• At the time of writing we believe that no notified test house is able to

test the largest 4.0 meter diameter non-series produced central

tunnel fans.

EN 12101-3 Compliance (and subsequent ISO 21927-3 and SI 1001-Part 7 Compliance)

Six different and independent factors that must be adequately taken

into account during a high temperature test are identified:

• Horizontally mounted vs. vertically mounted.

• Internal hot gas only vs. surrounded by hot gas.

• Insulated vs. non-insulated.

• Uni-directional vs. reversible.

• Auxiliary systems, direct on-line or inverter driven during fire.

• Form A vs. form B running.

EN, ISO & SI Compliance Testing

• Only notified bodies can perform EN12101-3 testing in order to certify fan

manufacturers high temperature fans. Currently any fan manufacture can

state compliance to ISO 21927-3 if they can test the product.

• It is possible, (although expensive) to certify large fans and or custom

designed fans. e.g. Fläkt Woods has successfully EN12101-3 certified a

2.65 meter diameter fan with a 900kw motor.

• Fan manufacturers outside the EU who are required to comply with ISO

29127-3 and SI 1001-Part 7 will be able to self certify their product.

Manufacturers inside the EU will be required to obtain 3rd party

independent certification.

ISO 21927-3

• The standard ISO 21927-3 does not contain the requirement for CE marking in accordance with the Construction Products Directive.

• The requirements of ISO 21927-3 are presented in:

Sheard, A.G. & Jones, N.M. (2008), ‘Approval of High-Temperature Emergency Tunnel-Ventilation Fans: The Impact of ISO 21927-3’. Proceedings of the ITA–AITES World Tunnel Congress and 34th General Assembly. Agra, India, 19–25 September, pp 1817–26.

• In practice ISO 21927-3 is the international version of EN 12101-3 for application outside EU member states.

• The standard SI 1001 Part 7 is ISO 21927-3, with the introduction and some key elements translated into Hebrew.

• The majority of SI 1001 Part 7 is the text from ISO 21927-3, to the extent that the ISO 21927-3 reference remains at the top of each page.

• Any product that compiles with the requirements of ISO 21927-3 also complies with the requirements of SI 1001 Part 7.

SI 1001 Part 7

• Currently there are no standards to certify HT Products for the Israel market. The existing requirement for 250/2 does not account for the fan running under load test.

• All European manufacturers who are EN12101-3 certified will qualify for compliance to SI 1001 Part 7 as a matter of course.

• All manufacturers who do not have existing EN or ISO compliance will need to either invest in their own temperature test rig or pay an existing test house to carry out the test.

• A reasonable timescale should be considered to allow the transition into a working standard.

SI 1001 Part 7 – Implementing the Standard

Fläkt Woods

• Fläkt Woods policy is to supply fans for emergency application that comply with the requirements of EN 12101-3.

• Fläkt Woods have EN 12101-3 certified products certified at 200C for 2 hours, 300C for 2 hours and 400C for 2 hours.

• Fläkt Woods have tested the highest power fan in accordance with the requirement of EN 12101-3 – a 1000 kW fan (at 400C for 2 hours), and the largest diameter fan – a 2.8 meter fan (at 300C for 2 hours).

• Fläkt Woods has spent ten years and in excess of £1,000,000 undertaking certification in accordance with the requirements of EN 12101-3.

• All Fläkt Woods products certified in accordance with the requirements of EN 12101-3 are also compliant with the requirements of ISO 21927-3 and SI 1001 Part 7.
