Polyurethane and Fire: Fire Performance Testing Under Real Conditions



Polyurethane and Fire: Fire Performance Testing Under Real Conditions

F. H. Prager, Helmut Rosteck

ISBN: 978-3-527-60771-6 August 2006 517 Pages


A survey of all facets of the fire performance examination and evaluation of flexible and rigid polyurethane foams in the various fields of building construction, furniture and furnishings, transportation and electric appliances. The basic information concerning the relevance of the different test procedures allows realistic requirements to be set, guaranteeing more safety in the case of fire. The legal requirements are based on laboratory test methods and the book describes their relevance in relation to real fire scenarios.
A must-have reference for producers, suppliers and manufacturers of polyurethanes.
