34、 bodies). The work of preparing International Standards is normally carried out through 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
35、 and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates 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 Directiv
36、es, Part 2. The main task of technical committees is to prepare International Standards. 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

It has been prepared in order to: a) introduce the principle of three performance levels for heat transmission performance properties, with the exception of a

47、and flame, which could be worn for a wide range of end uses. All the other standards listed in the Foreword deal also with clothing to protect against heat and fire, but rather for quite specific products or end uses. Within many of the hazards listed in this International Standard there are three p
48、erformance levels: Level 1 to indicate exposure to perceived low risk; Level 2 to indicate exposure to perceived medium risk; Level 3 to indicate exposure to perceived high risk. For protection against extreme exposures to radiant heat, there is a fourth performance level to take into account high p
49、erformance materials such as aluminized and similar materials. The level of personal protection to be provided is based on the outcome of the risk assessment and some comments on risk assessment are given in Annex E. In this International Standard, an informative annex on ergonomic features (Annex D) is included in the form of guidelines. Suitable tests for these requirements have not yet been validated internationally. For complete protection against exposure to heat and/or flame, it is probable that i
