This International Standard 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 itself constituting a hazard. Additional
requirements for 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 standard is not
appropriate. Standards such as ISO 11612, should be used.
A classification system is given for materials, material assemblies and garments which are tested according to
ISO 15025, Procedure A.
