Standards Development

Scope

This document specifies requirements for factory-made expanded perlite products, which are used for building and industrial installations, with an operating temperature range of approximately 0 °C to +1100 °C.

This document covers product characteristics including procedures for testing, evaluation of conformity, marking, labeling and packaging

Purpose

Expanded perlite thermal insulation products are made of expanded perlite and binders in factory. Expanded perlite thermal insulation products are not only low density, have good thermal insulation properties, good fire-proof, mildew-proof, and have water-proof performance, but also much better strength performance than the normal fiber insulation products. Expanded perlite products have been used widely in building envelope, industrial pipe systems,ovens and furnaces etc for a long history.

There are many national standards of Expanded perlite thermal insulation products in the world ,such as ASTM C610-17 “Standard Specification for Molder Expanded Perlite Block and Pipe Thermal Insulation” in US , JIS A 9501:2016 “Inorganic Cellular thermal insulation ” in Japan and GB/T 10303- 2015”Expanded perlite thermal insulation ” in China . Also there is EN 15501:2015 “Thermal insulation products for building equipment and industrial installations----Factory made expanded perlite (EP) and exfoliated vermiculite (EV) products----Specification ” in Europe.

In the above standards some of them are complicated and some of them are simple. They are different methods of specifying Expanded perlite thermal insulation products properties.

So one ISO standard of Expanded perlite thermal insulation products is valuable to harmonize the different formulation methods and have more countries to adopt the potential ISO standard in future.

This ISO document will harmonize the technical difference between countries and promote international trade.
