3.1. TEST PROCEDURE

The large-scale fire propagation properties of the system were evaluated by performing a test in the FIRELAB’s large-scale SANS 10177 – 11 roof insulation test facility. A schematic diagram of the test facility with the specimen frames is shown in Figure 3.2.1. The facility was equipped with a typical water sprinkler system to observe any obstructions during the event of testing; however, no water has been applied. The use of water during a test is dependent upon the client’s request. The ignition source for the under-roof evaluation was constructed from 60 kg dry 38 mm x 38 mm SA Pine sticks stacked in an open-crib configuration to form a 1 000 mm x 750 mm x 480 mm high crib. The pack was ignited with commercial firelighters at each corner, in order to simulate a fire with slow heat build-up. The maximum heat output of the fire source (approximately 2.5 MW based on previous research) occurred after approximately 12 minutes. The fire source was located at one end of the facility, approximately 1.5 m from the front end, 1.5 m from the side and 1.5 m from the center line of the specimen frame. The position of the crib is indicated in Figure 3.2.1. Only the first two panels were used for the test. No mass loss measurements were taken during the evaluations. This test was performed simulating an over-purlin suspended wire insulation system. This evaluation investigated the fire propagation properties of the roof insulation with the purlins positioned across the width of the test facility. A schematic side view of a typical roof test installation is shown in Figure 3.2.2. For this evaluation, the specimen frames were aligned in such a way that the roof slope was equal to 3 degrees. The distance between the top of the fire source and the roof directly above it was 2.7 meters. Note: The third 6 m by 6 m panel (end) was not used during this evaluation. 3.2. TEST EQUIPMENT

The Test Report and results only relate to the product(s) and/or sample(s) submitted for testing as identified in Section 2 and Annexures and do not apply to any similar product(s) or sample(s) that has not been tested. This Test Report is only valid for 5 years or until there is a change to the product composition, manufacturing process or previously approved supplier(s). The validity of this report may be extended by a validation certificate issued by FIRELAB upon verification of the product(s) or sample(s). 5. DISCUSSION OF RESULTS

The specimen softened, followed by the material sufficiently coagulating and draping, preventing the material from reaching its ignition temperature. Softened debris was observed during the test. No ignition was observed. Most of the debris dropping down occurred inside the Fire Source Area (0 – 4 m). For this evaluation a Fixed Water Suppression (Sprinkler) system, without water, was installed. Some of the material draped over the sprinkler pipes during the test; this may affect the operation of a sprinkler installation. Draping occurred approximately 8 minutes into the start of the test, at which time operational sprinklers might have already activated; therefore it is not clear from the test whether the draping would occur if an active sprinkler system is used. It is recommended that a second test, with an operation sprinkler system, be conducted to determine whether or not the functioning of the sprinklers will be affected.


The Test Report and results only relate to the product(s) and/or sample(s) submitted for testing as identified in Section 2 and Annexures and do not apply to any similar product(s) or sample(s) that has not been tested. This Test Report is only valid for 5 years or until there is a change to the product composition, manufacturing process or previously approved supplier(s). The validity of this report may be extended by a validation certificate issued by FIRELAB upon verification of the product(s) or sample(s). 6. CONCLUSION

The 40 mm IsoLam Ceiling Boards supplied by Isowall Southern Africa was classified in accordance with SANS 428 using the SANS 10177 –11 Horizontal test protocol. Classification in accordance with SANS 428:

SANS 10177 – 11 » B/ B1/ 2/ H (USP)*

* Although the panel preformed satisfactory without sprinklers, a test with an operational

sprinkler installation is recommended. Provision for adequate roof ventilation and/or a sprinkler protection system will need to be considered based on the size, slope and configuration of each roof. This should form part of the Fire Safety Design of the building in order to satisfy the requirements as contemplated by SANS 10400 – T. The above does not relate to Fire Resistance. Should Fire Resistance be a requirement, the system needs to be tested using the SANS 10177 – 2 test protocol.
