BS ISO 20310:2018 pdf download.Thermal insulation for building equipment and industrial installations – Aluminosilicate wool products – Specification
1 Scope
This document specifies the classification, requirements and test methods for factory-made aluminosilicate wool products which are used for thermal insulation of industrial installations and building equipment, for non-refractory applications. The products are delivered as blanket, module, felt,board, paper, textile and other forms.
This document describes product characteristics and testing methods, marking and labelling.
This document does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application.

3.1 aluminosilicate wool
ASW
amorphous High Temperature Insulating Wool (HTIW) manufactured predominantly from molten raw minerals
Note 1 to entry: The main ingredients are Al 2 O 3 and SiO 2 , and may contain ZrO 2 and Cr 2 O 3 .
3.2 aluminosilicate module
aluminosilicate wool (3.1) blanket formed into thick sections by needling, stacking or folding sheets,compressed to a higher density and typically supplied with integral anchoring systems
3.3 aluminosilicate paper
thin and flexible insulating material formed on a paper-making machine
5.3 Permanent linear change
Permanent linear change upon heating shall not be greater than 4,0 %. The test temperature shall be at the classification temperature as per Table 1.
5.4 Thermal conductivity
The manufacturer shall make declaration for the thermal conductivity λ D . The table or curve of conductivity versus temperature (from 200 °C up to 1 100 °C, where applicable) shall be given according to ISO 13787. Thermal conductivity shall be based upon measurements carried out in accordance with ISO 8302 up to 800°C and shall be in accordance with ISO 8894-1 or ISO 10635 for temperatures above 800 °C.
