1 Scope
The purpose of this document is to provide the principles and guidance for the preparation of
extended application documents for penetration sealing systems tested in accordance with
prEN 1366-3. The field of the extended application document is additional to the direct field of
application given within prEN 1366-3 and may be applied to or based on a single test, or a number of
tests, which provide the relevant information for the formulation of an extended application.

references, only the edition cited applies. For undated references, the latest edition of the referenced

4 Extended application principles
Due to the diverse nature of materials and constructions used to seal openings in fire resistant
separating elements it has been necessary to separate the extended application principles into
generic seal types. Principles common to all generic seal types are given in Section 4.1. Principles
and guidance relating to each specific generic seal type are given in annex A to this document.
Annex B provides guidance on the application of test results on plastic pipe seals.
Variables for each seal type, which require consideration, are included in this report. These are as
follows:
⎯ Separating element.
⎯ Type of service.
⎯ Size of service
⎯ Seal size and configuration.
Each section gives the possible variation, the expected effect and a comment on that effect. The
effects are annotated as + (a positive effect expected), - (a negative effect expected) or = (no
significant effect expected). Where no annotation of effect is given the comments are considered as
guidance.
Calculations can be used to determine the heat transfer and temperature increase along metallic
pipes, providing that the heat transfer within the pipe is taken into account.
At present this document only considers the effect of one variation at a time, all other parameters
remaining unchanged.
Where more than one variation is to be incorporated the overall effect must be considered.
4.1 General
The guidance given in this section is applicable to all generic penetration seal types incorporated in
annex A, unless stated otherwise in the specific section.
Seal material (primary generic penetration seal material as per Annex A)

Change of material(s) - Not acceptable.

This section relates to the change of material only used to back a mastic/sealant, elastomer or gel
when used as part of a penetration seal
Backing material Effect Comment
Polyethylene = or + May be replaced by glass wool, stone wool or
ceramic wool
Glass wool = or + May be replaced by stone wool or ceramic

Stone wool = or + May be replaced by ceramic wool
Ceramic wool (including = May only be replaced by alternative material of

alkaline earth silicate fibres
Separating elements — Concrete or masonry
Variation Effect Comment
Decrease in thickness - Not acceptable

Separating elements – Flexible constructions
Variation Effect Comment
Decrease in thickness - Not acceptable.
Increase in thickness = or + Acceptable.
Non standard elements Constructions not defined in EN 1366-3 must
be tested.
Change of linings = Acceptable for the constructions given in EN
1366-3 if the linings have an equivalent or
greater thickness and the construction
(horizontal or vertical) has an equivalent or
greater fire resistance.
Change in aperture framing - Not acceptable.

Insulated pipes Data relating to insulated pipes cannot be
used to support assessments in respect of
uninsulated pipes and vice versa.
Change of insulation For pre-insulated pipes a change of insulation
material. material is not acceptable. For post-insulated
pipes insulation material may be changed
within the same generic type, such as rock
fibre, glass wools, PVC’s etc where the
alternative provides an equivalent or greater
reaction to fire classification.

Variation Effect Comment
Decrease in size = Acceptable subject to not exceeding the ratio
of overall CSA of cable(s) to the internal CSA

Inclusion of trunking If cable trunking has not been included in
tests, results from cable trays of same generic
material and thickness can be used. The
perimeter of the trunking shall not exceed the
maximum cable tray width and an internal
seal must be provided within the trunking
coincident with the position of external seal.
CSA of cable(s) may be up to 60% of the
internal CSA of the trunking.
Conduits – As pipes (steel or plastic as appropriate).
Busbars – No changes acceptable.
Support conditions – Distance of support from the face of the seal must not exceed that tested.
