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).
