Combustion properties of interest in cellular plastics and elastomers include ease of ignition (ignitibility), support of combustion (oxygen index), relative extent and time of burning, surface flammability, flame read, smoke evolution properties, and rate of beat release. The following test methods are either concerned solely with cellular plastics, m are used for both cellular and solid plastics. 

In contrast to the considerable number of fire tests for plastics, there are relatively few fire tests specifically for rubbers as such. There are a number of tests for rubber products including cable insulation, hoses of various types, and cellular products. In some cases, e.g.. cellular products, the test relates to both cellular plastics and rubbers, e.g.. BS 4735 and ISO 3582. Horizontal burning characteristics when subjected to a small flame or BS 5111. Determination of smoke generation. For convenience, these have been described in the section dealing with plastics tests, Other tests for rubber products include ISO 8030 [51], Flammability of rubber hoses for underground mining, ISO 3401 [52], Conveyor belts Flame retardation specification and test method, and BS 5173, Part 103 [53], Fire rc.sistance of plastics and rubber hoses and hose assemblies, and linings of hoses, etc. 

Foamed cellular plastics provide a number of advantages, however, they can also bring two important problems as well. These are, the problems of the residual chemicals that may be left in the system and the problem of the flammability and smoke evolution on combustion . In addition, there can certainly be residues of unreacted monomer(s), blowing agent(s), polyols, catalyst(s). Are retardants left if the system is not prepared carefully, all of these can be left or trapped in the system (inside the internal cells). These...

Cellular urea-formaldehyde and phenolic resin foams have been used to some extent in interior sound-absorbing floors [101]. In general, cost, flammability, and cleaning difficulties have prevented extension into the acoustic tile market. Plastic foams are used in anechoic chambers [66]. 

Because of their superior insulating properties, foam plastics have found numerous applications in the construction and packaging industries. Along with increased use, a considerable amount of concern has been expressed in regard to the flammability of foam plastics. A detailed discussion of various tests used in the industry to determine the flammability of cellular and noncellular plastics and their limitations is included in Chapter 8. 

The flammability properties of this material (or any other material) are not intended to reflect the fire hazards presented by any resultant cellular or foamed plastic proouct...
