Other critical factors are the diameter of the collar, the type of intumescent and the ratio of the intumescent material to the enclosed area of the collar. The use of the same collar and the same pipe material eliminates most of the performance effecting variations and therefore only the pipe diameter and wall thickness need to be considered. The table above lists the penetration systems tested along with the additional systems requiring assessment. Addressing the performance requirements of the system it is considered that if the same collar is used to protect penetrations incorporating plastic pipes of the same material of maximum dimensions and minimum dimensions and both achieve the same fire-resistance levels then the same fire-resistance levels can be assigned to plastic pipes of the same material whose dimension fall between those of the tested systems. Additionally the consistency of performance can be taken into account in that if the protection achieves the same result over a relatively extensive rang of pipes of the same material then interpolation between the tests may be possible. These criteria are satisfied by all of the proposed systems listed above.

11 Page 11 of 13 pages Additionally, as part of the test programme, you installed five wall and five floor penetrations incorporating variously sized PVC pipes protected by your CP 648 Firestop wraps. The testing was conducted using your CP 648-E system in which a continuous wrap is wound spirally around the pipe to provide the specified number of layers. An alternative is to use a series of single discrete strips cut to length equivalent to the diameter of the pipe or the previous wrap layer. This system is designated CP 648-S Firestop wraps and would provide equivalent or marginally more intumescent material and therefore would not detrimentally affect the established fire performance if the CP 648-E was replaced with the CP 648-S system. CONCLUSION Based on the test information and the performance factors detailed above it is the opinion of the Division that the penetration systems listed below would be capable of achieving the stated fire-resistance levels if tested in accordance with AS and AS when installed into concrete, blockwork, masonry or Hebel wall systems of nominated minimum thickness provided that the pipe is not of sandwich construction and is manufactured in accordance with the standards listed above or equivalent.
