ISO 22482-2021 pdf free download – Thermal insulation products — Aerogel blanket for buildings — Specification.
This document specifies the requirements for factory-made aerogel blankets,which are used for thethermal insulation of building applications. This document specifies insulation that exhibits thermalinsulating performance through high porosity and nano-sized pores by compounding aerogel with net-like fibrous material, e.g.polyester, glass fibre, ceramic fibre.The products are delivered as a blankettype.
This document describes product characteristics and includes procedures for testing, evaluation ofconformity and marking and labelling.
This document does not specify the required level of a given property to be achieved by a product todemonstrate fitness for purpose in a particular application.

4 Requirements
4.1 General
Product properties shall be assessed in accordance with Clause 5. To be in conformance with thisdocument, products shall meet the requirements of 4.2 and 4.3, as appropriate.
The test methods for determination of each property are given in Table 5,which also showsthe requiredtest specimen dimensions and the minimum number of test specimens required to give one test result.One test result for a product property is the average of the measured values on the number of testspecimens given in Table 5.
4.2 For all applications4.2.1 Linear dimensions
Length and width shall be measured in accordance with IlSO 29465 for each of the four specimens.A minimum of four measurements shall be made for each dimension. Each value shall be within thetolerances specified in Table 1.
The thickness of aerogel insulation shall be measured in accordance with ISO 29466 by using a squareplate under pressure of not less than 250 Pa and shall be subject to the tolerances detailed in Table 1.The pressure employed during measurement shall be disclosed.
Tighter tolerances can be necessary for certain applications; this shall be agreed to by the supplier andpurchaser.
4.2.2 Density
Density shall be determined in accordance with ISO 29470 in each of the four specimens and reported as the average of the four specimens.ISO 22482 pdf download.
