What is BS EN 15882-5-about?
BS EN 15882-5 is the fifth part of a multi-series that specifies the principles and guidance for the preparation of extended application documents for combined penetration seals, where the systems were tested in accordance with (EN 1366‑3 and EN 1366‑1) or (EN 1366‑3 and EN 1366‑2). This EXAP is intended to allow the penetration sealing of more than one service
(e.g., cables, pipes, conduits) and four-sided fire resisting ducts (ventilation ducts) or fire dampers in the same penetration.
The field of the EXAP document is added to the direct field of application given within EN 1366‑1, EN 1366‑2, and EN 1366‑3 and can be applied on several tests from each standard, which provide the relevant information for the formulation of an extended application.
Test results from this EXAP can only be used for combined penetration seals.
Note 1: This EXAP is not used for extended applications in accordance with EN 1366‑8, EN 1366‑10, and/or EN 1366‑12.
Note 2: Ducts tested in standard supporting construction without an additional penetration sealing system are not suitable for testing in line with this standard.
Who is BS EN 15882-5 for?
BS EN 15882-5 on the preparation of EXAP documents for penetration seals is particularly useful for:
- Users of BS EN 1366‑1, BS EN 1366‑2 and/or BS EN 1366‑3
- Manufacturers and dealers of fire-resistant seals ducts and dampers
- Entities involved with penetration sealing systems
- Civil engineers
- Contractors
Why should you use BS EN 15882-5?
A penetration seal is a passive form of fire protection system that aims to maintain the fire resistance of a building section such as wall, ceiling or floor.
Where a penetration sealing system is used to maintain the fire resistance of a separating element at the position where one or more services in accordance with BS EN 1366-3, BS EN 1366-1 and/or BS EN 1366-2 to pass through, the requirements under BS EN 15882-5 shall be used.
BS EN 15882-5 provides the required basic tests to enable the use of the EXAP test for penetration sealing of various services as well as ventilation ducts or fire dampers in the same penetration.
In any combined service penetration test in accordance with BS EN 15882-5, it is not the intention to retest the penetration sealing system but to identify if there are any interface effects between the fire resisting duct and other services that can cause the whole system to fail, such as radiating heat from the fire resisting duct or any service passing through the penetration seal.
Due to the diverse nature of materials and constructions used to seal openings in fire resistant separating elements, it is necessary to separate the extended application principles into generic seal types. Principles common to all generic penetration seal types are given in BS EN 1366-3.
By specifying the rules for field of extended application for supporting construction, fire damper dimensions and position and distances of the penetrating services, BS EN 15882-5 helps you build a precise field of application process.
Overall, being a supporting document for BS EN 13661, BS EN 13662 and BS EN 13663, BS EN 15882-5 will help you gain a holistic perspective on the delivery of safe and efficient products and services. Apart from safety and protection, you could also benefit from reduction in maintenance costs, prolonged service-life and prospects of business expansion
