This standard BS EN 15659:2019 Secure storage units. Classification and methods of test for resistance to fire. Light fire storage units is classified in these ICS categories:
13.310 Protection against crime
13.220.40 Ignitability and burning behaviour of materials and products
This document specifies requirements for light fire storage units providing protection against fire. The method of test is specified to determine the ability of light fire storage units to protect paper media from the effects of fire. Two levels of fire exposure periods (LFS 30 and LFS 60) are specified using the maximum temperature increase permitted within the storage space of the light fire storage unit. Protection after the fire exposure of 30 min (LFS 30) or 60 min (LFS 60) is not ensured by this document, but by European Standard EN 1047-1. Requirements are also specified for the test specimen, the technical documentation for the test specimen, correlation of the test specimen with the technical documentation, preparation for type testing and test procedures. A scheme to classify the light fire storage units from the test results is also given (see Table 1).
