Resumen

ϲʿ 22262-2:2014 specifies procedures for quantification of asbestos mass fractions below approximately 5 %, and quantitative determination of asbestos in vermiculite, other industrial minerals and commercial products that incorporate these minerals.

ϲʿ 22262-2:2014 is applicable to the quantitative analysis of:

a) any material for which the estimate of asbestos mass fraction obtained using ϲʿ 22262-1 is deemed to be of insufficient precision to reliably classify the regulatory status of the material, or for which it is considered necessary to obtain further evidence to demonstrate the absence of asbestos;

b) resilient floor tiles, asphaltic materials, roofing felts and any other materials in which asbestos is embedded in an organic matrix;

c) wall and ceiling plasters, with or without aggregate;

d) mineral products such as wollastonite, dolomite, calcite, talc or vermiculite, and commercial products containing these minerals.

It is not the intent of ϲʿ 22262 to provide instruction in the fundamental microscopical and analytical techniques.
