(5)pipes, trunking and conduits of reaction to fire class A1 or A2 according to EN 13501-1 with a melting or decomposition point equal to or less than 1000°C (e.g. lead, aluminium and aluminium alloys) and/or the risk of fracture (glass, fibre cement), either insulated or non-insulated.
(6)pipes not classified to A1 or A2 according to EN 13501-1 (e.g. made from thermoplastic or thermosetting material) including non-homogeneous materials (e.g. glass fibre reinforced plastic pipes or layered pipes), either insulated or non-insulated, hereafter referred to as "plastic pipes".
(7)trunking and conduits not classified to A1 or A2 according to EN 13501-1 (e.g. made from thermoplastic material or thermosetting material) including non-homogeneous materials, either insulated or non-insulated, hereafter referred to as "plastic trunkings” and “plastic conduits”.
A penetration seal may contain either a single type of the services described above, or various types (mixed penetrations). The number of services may vary (including blank penetration seals where no services are included). The services may or may not include service support constructions (e.g. cable trays).
Penetration seals may be used in various environmental conditions, described by the following use categories, related to the type of environmental conditions. These are based on the general principles specified in Part 1 – "General". The use categories are:
Type X: Products for penetration seals intended for use at conditions exposed to weathering.
Type Y1: Products for penetration seals intended for use at temperatures below 0°C with exposure to UV but no exposure to rain
Type Y2: Products for penetration seals intended for use at temperatures below 0°C, but with no exposure to rain nor UV.
Type Z1: Products for penetration seals intended for use at internal conditions with high humidity, excluding temperatures below 0°C.2
Type Z2: Products for penetration seals intended for use at internal conditions with humidity classes other than Z1 excluding temperatures below 0°C.
Requirements relevant for the establishment of the use categories are presented in 2.4.12.
NOTE: Products that meet requirements for type X, meet the requirements for all other types. Products that meet requirements for type Y1 also meet the requirements for type Y2, Z1 and Z2. Products that meet the requirements for type Y2 also meet the requirements for type Z1 and Z2. Products that meet the requirements for type Z1, also meet the requirements for type Z2.
Note, however, that although it is acceptable for a penetration seal to be intended for indoor applications only, the construction process may result in it being subjected to more exposed conditions for a period before the building envelope is closed. In this case there are two possibilities:
Special provisions are made to temporarily protect the exposed penetration seals according to the instructions of the manufacturer which are referenced in the ETA.
The penetration seal should be evaluated as if it were to be used for exposed applications (type X).
The product’s resistance to environmental conditions other than those listed above is not covered in this part of the ETAG (see 188.8.131.52.1) and may be assessed on a case by case basis as necessary. The approval body shall obtain suitable evidence for the assessment and present details in the ETA.
1.3 Assumed working life of the construction product
The provisions and the verification and assessment methods included or referred to in this ETAG have been written based upon the assumed working life of the Fire Stopping and/or Fire Sealing Product for the intended use of 25 years when installed in the works, provided that the Fire Stopping and/or Fire Sealing Product is subject to appropriate use and maintenance (see 4.4). However, if the product is a reactive material or includes a reactive material, the working life is assumed to be 10 or 25 years depending on available evidence. These provisions are based upon the current state of the art and the available knowledge and experience.
Additional assumptions made are given in Part 1 – "General".
