4 Executive summary This report provides the assessment of this Division on the likely fire performance of the pipe penetration system. You propose to determine the likely fire resistance levels (FRL) of the pipe penetration systems tested in accordance with draft Standard pren :1996 and reported in TE from the Loss Prevention Council Laboratories, UK. It is the opinion of this Division that the nine penetration systems report in TE would be capable of achieving the following fire resistance levels (FRL) if tested in accordance with AS System FRL 1 /60/60 2 /240/90 3 /240/90 4 /240/60 5 /180/60 6 /240/90 7 /240/60 8 /120/60 9 /90/60 This assessment applies to the following products, protecting a 80 mm diameter steel pipe penetrating a 150 mm thick AAC block wall, installed as detailed in Loss Prevention Council, UK, report numbered TE 91647, dated 22 February FR Canister Foam (5034 )..

5 Likely performance of metal pipe penetration systems 1 Introduction This report provides the assessment of this Division on the likely fire performance of various metal pipe penetration systems tested in accordance with pren : Supporting Data A full scale ad hoc test on pipe penetrations was conducted on 5 October 1998 by the Loss Prevention Council Laboratories, UK. This test report is described in Appendix A. 3 Proposal You propose to determine the likely fire resistance levels (FRL) of the pipe penetration systems tested in accordance with draft Standard pren :1996 and reported in TE from the Loss Prevention Council Laboratories, UK, in terms of the performance requirements of AS Analysis The draft Standard pren :1996 is very similar to AS with the main differences being the control of the furnace using plate thermometers and the number of specimen thermocouples. The plate thermometer and the MIMS thermocouple utilised in the Australian Standard have been evaluated in the Division s furnaces and little difference in the furnace conditions has been noted. The use of a single specimen thermocouple at each location other than the two specified by AS could potentially miss earlier failures but in this test the specimen thermocouples were installed above the penetration and this is usually the most onerous location for vertical specimens penetrated by services.

7 Appendix A Supporting data A.1 Loss Prevention Council Laboratories, UK report numbered TE On 5 October 1998 nine pipe penetration sealing systems each fitted to a 34 mm diameter steel pipe passing through separate apertures in a 150 mm thick aerated concrete blockwork wall were submitted to an ad hoc fire resistance test in accordance with the procedures and criteria of draft Standard pren :1996. System 1 comprised an 80 mm diameter aperture sealed with polyurethane canister foam ref The system failed insulation at 60 minutes and integrity at 84 minutes due to ignition of the cotton pad. System 2 comprised an 80 mm diameter aperture sealed with polyurethane canister foam, ref. 5034, capped on each face with 10 mm thick intumescent acrylic sealant, ref The system failed insulation at 114 minutes but did not fail integrity for the full 240 minute duration of the test. System 3 comprised an 80 mm diameter aperture sealed with polyurethane canister foam, ref. 5034, capped on each face with 10 mm thick low modulus neutral cure silicone, ref The system failed insulation at 102 minutes but did not fail integrity for the full 240 minute duration of the test. System 4 comprised an 80 mm diameter aperture sealed with polyurethane canister foam, ref. 5034, capped on each face with 10 mm thick intumescent putty, ref The system failed insulation at 82 minutes but did not fail integrity for the full 240 minute duration of the test. System 5 comprised an 80 mm diameter aperture sealed with polyurethane canister foam, ref. 5034, capped on each face with 1.5 mm thick intumescent paint, ref The system failed insulation at 65 minutes and failed integrity at 187 minutes because of sustained flaming. System 6 comprised an 85 mm aperture sealed with intumescent rubber, ref. 8152, wrapped around the pipe to a thickness of 4 mm and the void filled with polyurethane canister foam, ref The system failed insulation at 109 minutes but did not fail integrity for the full 240 minute duration of the test. System 7 comprised an 85 mm aperture sealed with 4 mm thick intumescent fibre, ref. 8253, wrapped around the pipe and the void filled with polyurethane canister foam, ref The system failed insulation at 75 minutes but did not fail integrity for the full 240 minute duration of the test. System 8 comprised a 105 mm aperture sealed with 14 mm thick intumescent rubber and foam composite, ref. 8354, wrapped around the pipe and the void filled with polyurethane canister foam, ref The system failed insulation at 75 minutes and failed integrity at 146 minute due to ignition of the cotton pad. System 9 comprised an 85 mm aperture sealed with ceramic tape, ref. 8556, wrapped around the pipe to a thickness of 4 mm and the void filled with polyurethane canister foam, ref The system failed insulation at 60 minutes and failed integrity at 110 minute due to ignition of the cotton pad.
