Building products ignitability Apparatus

Description

This apparatus is manufactured to conform to ISO 5657.The Apparatus has been designed,principally for testing building materials and composites, but it is capable of testing any sample of size 165mm × 165mm and up to a maximum of 70mm thick. The Apparatus measures

the ignition characteristics of exposed surfaces of essentially flat materials and specimens.
