Determination of asbestos in building material products - Part 3: Quantitative analysis of containing asbestos by X-ray diffraction method
|Publication Date:||28 March 2014|
|ICS Code (Ambient atmospheres):||13.040.20|
This Standard specifies the method of determining asbestos content (mass fraction) (hereafter referred to as "asbestos content") in building material products by the X-ray diffraction analysis method. It consists of procedures for preparation of secondary and tertiary analytical samples for quantitative determination, and the X-ray diffraction method employing the absorption correction by basal standard method.
It is not applicable to natural minerals which can contain asbestos as impurities or any products that are made of such natural minerals.
For criteria to be applied for the analysis, those stipulated by the following domestic laws and regulations shall prevail over those specified in this Standard.
Industrial Safety and Health Act
Waste Management and Public Cleansing Act
NOTE 1 JIS A 1481-1 is applicable to asbestos analysis for both building material products and natural minerals. JIS A 1481-2 and JIS A 1481-3, on the other hand, are only applicable to asbestos analysis for building material products and not applicable to analysis for natural minerals which can contain asbestos or any products that are made of such natural minerals.
NOTE 2 Figure 1 shows the flow chart for judgement of asbestos content of 0.1 %.
