ISO 14116 Protective clothing – Protection against heat and flame – Limited flame spread materials, material assemblies and clothing

1 Scope

This International Standard specifies the performance requirements for the limited flame spread properties of materials, material assemblies and protective clothing in order to reduce the possibility of the clothing burning
and thereby itself constituting a hazard. Additional requirements for clothing are also specified.

Protective clothing complying with this International Standard is intended to protect workers against occasional and brief contact with small igniting flames, in circumstances where there is no significant heat
hazard and without the presence of another type of heat. When protection against heat hazards is necessary in addition to protection against limited spread flammability, then standards, such as ISO 11612, are more
appropriate.

A classification system is given for materials, material assemblies and garments which are tested according to
ISO 15025:2000, Procedure A.
