JIS A 1481:2008 建材製品中のアスベストの測定規格と仕様

範囲: This Japanese Industrial Standard specifies the determination method of asbestos in building material products by dispersion staining phase-contrast micros- copy and X-ray diffractometry. This standard consists of the preparation of primary analytical sample, the qualitative analytical method for primary analytical sample, the judgment of presence of asbestos, the preparation of secondary and tertiary samples for quantitative determination by X-ray diffraction method employing substrate standard mass absorption correction method. The building material products to be measured with this method are: fire proofing spraying material and the like, spraying material made of vermiculite, interior finish- ing material (moulded board), floor tile, exterior material (moulded board, mortar), roofing material, chimney material, heat insulating material, textile goods (cloth), sealing compound and expansion joint. However, this Standard shall not be applied to natural minerals which can contain asbestos or any products that are made of such natural mineral (excluding spraying material made of vermiculite).
