7、nd ii ISO 2008 All rights reserved ISO 14116:2008(E) ISO 2008 All rights reserved iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out th
8、rough ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collab
9、orates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Stan
10、dards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of

ISO 14116 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 162, Protective clothing including hand and arm protection and li
12、fejackets, in collaboration with Technical Committee ISO/TC 94, Personal safety Protective clothing and equipment, Subcommittee SC 13, Protective clothing, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). ISO 14116 supersedes EN 533:1997, which has be
13、en technically revised to include: a) the testing of clothing for limited contact with flames specified; b) the requirements for the design of clothing specified; c) the requirements for mechanical performance of clothing specified; d) the ageing due to washing specified (maximum number of cleaning
14、procedures as indicated by the manufacturer); e) the marking requirements modified; f) the information to be supplied by the manufacturer modified. -,-,- -,-,- INTERNATIONAL STANDARD ISO 14116:2008(E) ISO 2008 All rights reserved 1 Protective clothing Protection against heat and flame Limited flame
15、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 itsel
16、f 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
17、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
18、 which are tested according to ISO 15025:2000, Procedure A. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (i
