EN ISO 14116

Protective clothing - Protection against flame - Limited flame spread materials, material assemblies and clothing

EN ISO 14116 specifies the performance requirements for the limited flame spread properties of all materials, all material assemblies, and protective clothing in order to reduce the possibility of the clothing burning when in occasional and brief contact with small flames and thereby constituting a hazard. Additional requirements for EN ISO 14116 clothing are also specified, including design requirements, mechanical requirements, marking, and information supplied by the manufacturer.

When protection against heat hazards is necessary, in addition to protection against flame, this International Standard is not appropriate. International Standards such as EN ISO 11612 are to be used instead.
