1 Introduction

A series of fire resistance tests in accordance with EN 1366-3:2009 have been carried out on Suresnap fire collars fitted around plastic pipes penetrating concrete floors. This extended application report considers the fire performance of the fire collars when fitted around pipes of different materials, diameters and wall thicknesses.

2 Scope

This extended application report considers the fire performance of Suresnap fire collars, when fitted around plastic pipes passing through concrete floors, against the integrity and insulation criteria of EN 1366-3:2009, for fire exposures of up to 240 minutes from the underside. The extended application has been carried out in accordance with EN 15882-3:2009.

3 Supporting data

Details of the supporting data used in the preparation of this extended application are given in appendix A.

4 Description of the proposed fire collars

4.1 Suresnap cast-in H65S collar The Suresnap cast-in H65S collar, details of which are shown in figure 1, comprises a 1.6mm-thick polypropylene casing with an 84mm inner diameter and a 168mm-diameter base flange. The 250mm-high collar casing, which is cut down in length to match the floor thickness, incorporates a 280mm x 65mm x 5mm-thick intumescent sheet and a rubber ring seal. The closing mechanism comprises three 3.15mm-diameter galvanised steel springs bound with nylon fuse links and a 322mm x 63mm x 0.25mm-thick stainless steel mesh.

4.2 Suresnap cast-in H100S collar The Suresnap cast-in H100S collar, details of which are shown in figure 2, comprises a 1.6mm-thick polypropylene casing with a 126.5mm inner diameter and a 213mm-diameter base flange. The 250mm-high collar casing, which is cut down in length to match the floor thickness, incorporates a 412mm x 85mm x 4mm-thick intumescent sheet and a rubber ring seal. The closing mechanism comprises three 3.15mm-diameter galvanised steel springs bound with nylon fuse links and a 460mm x 83mm x 0.25mm-thick stainless steel mesh.

4.3 Suresnap cast-in H110S collar The Suresnap cast-in H110S collar, details of which are shown in figure 3, comprises a 1.9mm-thick polypropylene casing with a 138mm inner diameter and a 194mm x 184mm rectangular base flange. The 248mm-high collar casing, which is cut down in length to match the floor thickness, incorporates a 451mm x 85mm x 4mm-thick intumescent sheet and a rubber ring seal. The closing mechanism comprises four 3.15mm-diameter galvanised steel springs bound with nylon fuse links and a 503mm x 83mm x 0.25mm-thick stainless steel mesh.

4.4 Suresnap cast-in H150S collar The Suresnap cast-in H150S collar, details of which are shown in figure 4, comprises a 2mm-thick polypropylene casing with a 182mm inner diameter and a 292mm-diameter base flange. The 250mm-high collar casing, which is cut down in length to match the floor thickness, incorporates a 600mm x 110mm x 6mm-thick intumescent sheet and a rubber ring seal. The closing mechanism comprises four 4mm-diameter galvanised steel springs bound with nylon fuse links and a 640mm x 109mm x 0.25mm-thick stainless steel mesh.

4.5 Sealing around pipes Where there is a gap between the aperture in the floor and the pipe circumference, this is filled using one of the following methods:

a) For gaps up to 10mm wide: No backfill, Weber Saint Gobain No-shrink General Purpose Construction Grout or Sika Everbuild Everflex LMA 200 Contractors Sealant.

b) For gaps between 10mm wide and 20mm wide: Weber Saint Gobain No-shrink General Purpose Construction Grout or Sika Everbuild Everflex LMA 200 Contractors Sealant.

c) For gaps between 20mm wide and 30mm wide: Weber Saint Gobain No-shrink General Purpose Construction Grout.

Where Weber Saint Gobain No-shrink General Purpose Construction Grout is used, a cardboard gasket is located between the pipe and the aperture in the floor and the grout applied in the gap above this. The cardboard gasket is positioned either 30mm below the upper surface of the floor or on the rubber ring of the collar if this is less than 30mm below the surface of the floor.

Where Sika Everflex LMA 200 Contractors Sealant is used, this is applied between the pipe and the aperture in the floor to a depth of 10mm.

Where the pipes are grouted in, PE foam strip, nominally 5mm thick, may be applied around the pipe, flush with the top of the floor to the full depth of the grout. This is done for acoustic purposes. The PE strip may also be used in isolation where the gap between the pipe and the aperture in the floor is small, i.e. less than 10mm.

5 Extended application

5.1 Separating elements A decrease in the thickness or density of the supporting construction is not permitted. Therefore, as the tested fire collars were tested cast into concrete floor slabs with a thickness of 150mm and an average measured density of 2240kg/m3, this is the minimum permitted specification.

An increase in thickness of the supporting construction is permitted provided that the fire collar is installed so that it is flush with the underside of the floor slab.

5.2 Pipe dimensions A change in pipe dimensions is permitted within the diameter and wall thickness range tested provided the seal thickness and depth remains the same across the pipe dimension range. In the case of pipe closure devices this refers to the thickness and length of the intumescent component. For the purposes of this extended application report the H100S and H110S data has been combined as the thickness and length of the intumescent component is the same in both collar types.

The PE100 pipes detailed within the test reports are PE-HD pipes that comply with EN 1519-1.

5.2.1 PVC pipes with no pipe coupling within fire collar Table 1 summarises the test data for PVC pipes with no pipe coupling within the fire collar.

*Note: Fire collar 2 in BRE Global report no. P112838-1002 failed prematurely when it caught fire due to the sustained flaming from an adjacent specimen. Fire collar 2 in BRE Global report no. P112838-1005 failed prematurely due to the pipe slipping out of the collar. This was due to the deformation of the pipe allowing it to slip out of the support collar. This would not happen in practice. The results of these two specimens have therefore been ignored with respect to the extended application.

6 Conclusion

Therefore it is our opinion that the Suresnap Fire Collars, as described in section 4, will provide the classifications detailed in tables 2, 4, 6, 8, 10 and 12 against EN 13501-2:2016 when installed in concrete floors with a minimum thickness of 150mm.

8 Validity of the extended application

This assessment is issued on the basis of test data and information to hand at the time of issue. If contradictory evidence becomes available to BRE Global the extended application will be unconditionally withdrawn and the applicant will be notified in writing.

Similarly the extended application is invalidated if the assessed construction is subsequently tested since actual test data is deemed to take precedence over an expressed opinion. The extended application is valid for a period of five years after which it is recommended that it be submitted to BRE Global for re-evaluation.

Next review date: 07 May 2024
