Description

This document specifies the test and performance requirements for sandwich panels and built-up systems used internally in buildings, for compliance with the LPC Design Guide for the Fire Protection of Buildings. It is appropriate for sandwich panels used internally in food factory clean rooms, cold stores, and refrigerated spaces and for self-supporting builtup systems for use as room separation within a building. For wall and ceiling lining systems used for the external envelope of all types of industrial buildings refer to LPS 1181: Part 1.

The LPS1181 test series are used to determine the fire growth performance of the cladding products used in different applications. The performance determined relates only to the combination tested, i.e. the wall and roof panels, including the composition of the panels, the joint details and the detailing at eaves, corners etc. 

If a test is required to determine the performance of only a wall panel or a roof panel, the panel not being assessed shall be an LPCB approved product of similar insulation level (i.e. similar U-values) and shall have the same generic type of core material. Alternatively, another arrangement for the non-test panels may be agreed by LPCB. Limiting conditions applicable to the listing of the panel being tested may be set because of the combination being tested. The test arrangement and any limiting conditions shall be agreed in writing by LPCB and the panel manufacturer before testing commences. Details of test arrangements must be provided and approved by LPCB prior to the provision of the LPCB quotation for product approval. 

Note:- This document does not address quality of installation of these products within buildings. Quality of Installation requirements will be addressed in a separate standard.
