The work of preparing International Standards is normally carried out through IsO non-governmental,inliaisonwithIsO,also take part inthe work.Iso collaborates closely withthe International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2 adopted by the technical committees are circulated to the member bodies for voting.

When standards are established or existing specifications are revised on the basis of these guidelines, the values) in the International Standard for a product or application, together with appropriate test methods, requirements in service. This relationship between specified values for the product and the service performance characteristic of the product in use can be different for different insulating products, depending on the characteristic of the material (e.g. ageing or time-dependent behaviour). This International Standard applies only to prefabricated thermal-insulation prod
