MEETING THE DTS PROVISIONS OF THE BCAUSING TESTED SYSTEMS

Trevor KempsterNational Sales ManagerTBA Firefly


MEETING DTS COMPLIANCE WITH THE BCA (NCC) ISN’T A DIFFICULT CONCEPT/TASK ONCE YOU TAKE AWAY THE SMOKE AND MIRRORS

penetrating various wall substrates.


EVIDENCE OF SUITABILITY REQUIRED FOR PASSIVE FIRE PROTECTION COMPLIANCE

Non-compliance is costing millions of dollars in rectification works throughout AustraliaUntil recently industry has been happy to accept and sign off on the following:

• Test Certificates• Manufacturers Technical Installation Manuals• Glossy Data Sheets• EJ’s• Letters from Manufacturers• Letters from Suppliers• A Letter from your MumNone of which are a route to compliance under the BCA (NCC) where an FRL is required


COMPLIANCE IN ACCORDANCE WITH A2.2 EVIDENCE OF SUITABILITY FOR TESTED PASSIVE FIRE PROTECTION SYSTEMS

To satisfy A2.2 it states that clause A2.3 must be met and that Specification A2.3 applies to FRL’s without exception.Which is a report from a Registered Test Authority, there are no other options.


1. Regulatory Information Report or Assessment Report from a Registered Testing Authority which clearly lists:

• Which fire rated substrates the seals may be attached to• Maximum size of aperture seal• Orientation floor or wall (or ceiling)• Which services may pass through the seal if any


ON-SITE CONSTRUCTION VS RIR

For instance if it only addresses the fire stopping seals on a masonry wall substrate, it cannot be used on a FR Plasterboard wall substrate or if it only addresses a floor penetration it cannot be used for walls etc.• The on-site application does not vary in any way, from the

construction details contained in the RIR or Assessment Report. COMPLIANT. In accordance with Specification A2.3 PART 2 (c)

• If the on-site application varies, from the construction details contained in the RIR or Assessment Report. NON-COMPLIANT.


2. A single Test Report or multiple Test Reports from a Registered Testing Authority where the prototype is identical to the on-site application and does not vary in any way.Definition of Identical: similar in every detail, exactly alike.


COMPLIANT. In accordance with Specification A2.3 PART 2 (b)• A single Test Report or multiple Test Reports from a Registered

Testing Authority plus a Manufacturers Technical Installation Manual which shows variations to the Tested Prototypes. NON-COMPLIANT.

• A single Test Report or multiple Test Reports from a Registered Testing Authority plus a Manufacturers glossy data sheet which show variations to the Tested Prototypes. NON-COMPLIANT.


• A single Test Report or multiple Test Reports from a Registered Testing Authority plus a Manufacturers Internal Engineer, commonly known as an EJ (Engineered Judgment) which shows variations to the Tested Prototypes. NON-COMPLIANT.

• A single Test Report or multiple Test Reports from a Registered Testing Authority plus a letter from a Manufacturer which justifies or certifies variations of the Tested Prototypes. NON-COMPLIANT.


3. A Test Certificate from a Registered Testing Authority is for marketing purposes only and is not to be used for Regulatory Compliance and therefore. NON-COMPLIANT. In accordance with AS1530.4-2005 Section A2.15.4

THE INSULATION PART OF AN FRL MAY BE WAIVED ON ALL METAL PIPES (NOT QUITE THAT SIMPLE)

1. In accordance with C3.15 (a) Tested Systems (ii): The Insulation may be waived on pipes made entirely of metal which pass through a fire wall/floor if they have been Tested in accordance with AS1530.4 and AS4072.1 and achieved the required Integrity part of the FRL and:

• Any combustible building element is not able to be located within 100mm of the service for a distance of 2m from the penetration; and

• Combustible material is not able to be located within 100mm of the service for a distance of 2m from the penetration; and

• It is not located within a required exit.


• Requirements to meet this clause:A report from a Registered Test Authority which covers the following information:

a. The metal pipe has been tested in accordance with AS1530.4 and AS4072.1b. The fire stopping products usedc. The FRL achieved (Integrity)

d. Min-Max Pipe sizese. The specific substrate may pass through• There are various options to ensure that nothing combustible may be located within the 100mm exclusion

zone for a distance of 2m either side of the penetration:

a. Box-out from either side of the penetration for a distance of 2m from either side of the penetration.b. Create a metal cage around the metal pipe for a distance of 2m from either side of the penetration.c. Wrap out 2m using 100mm thick flexible non-combustible material Tested to AS1530.1

• It is not always possible to wrap out 2m to either side of the penetration due to space issues.


2. In accordance with C3.15 (c) Compliance with Specification C3.15To enable the insulation to be waived on metal pipes that are not normally filled with liquid the application must meet ALL of the following criteria:• The pipe must be made entirely of metal• The metal pipe must be in a single core hole that does not contain any other

services and the core hole must be a minimum of 200mm from any other service penetration

• The metal pipe cannot pass through more than 2 fire compartments• The pipe must have an exclusion zone of 100mm around its perimeter for a

distance of 2m either side of the fire wall/floor so that nothing combustible can come into contact with it


• The pipe does not contain flammable or combustible liquid or gas• In addition all of the requirements of Specification C3.15 PART 3 and

CLAUSE 7 must be met.• The gap between the metal pipe and wall/floor or ceiling must be

fire stopped using a fire stopping product which meets CLAUSE 7 of Specification C3.15

• Detailed in a report from a Registered Testing Authority that the fire stopping material has been tested to AS1530.4 and met the required FRL when tested using the Test Criteria contained within CLAUSE 7 (e) Test.


It’s quite a complicated and potentially expensive task to meet either of the 2 options when attempting to waive the Insulation criteria of a metal pipe due to the vast amount of restrictions which both solutions entail.


The easiest and most cost effective way to meet compliance is to simply specify a fire stopping product which meets C3.15 (a) Tested Systems (i) in full: Whereby the metal pipe and fire stopping system has been proven by test to meet the full Integrity and Insulation of the wall, floor or Ceiling of which it is passing through. Which is clearly detailed in a Regulatory Information Report or Assessment Report from a Registered Testing Authority.

FIRE PERFORMANCE OF EXTERNAL WALLS AND CLADDING

The ABCB released an advisory note in August 2016. The document explains which elements are considered to be part of an external wall.

• External cladding including masonry, concrete panels, composite panels and sheet materials

• Framing• Spandrels• Insulation• Internal Lining (e.g. plasterboard) of an external wallAll of which are required to be non-combustible, this includes the Sarking.


NON-COMBUSTIBILITY TEST

• AS1530.2 is a test where the Flammability Index of a product is determined. It is not a Non-Combustibility Test (far from it).

• AS1530.1 is the Non-Combustibility test. As far as I am aware, there is currently only one Manufacturer of Non-Combustible Sarking in Australia.
