ASTM D1712-09

Plastic compositions containing salts of lead, cadmium, copper, antimony, and certain other metals (as stabilizers, pigments, driers, or fillers) may stain due to the formation of a metallic sulfide when in contact with external materials that contain sulfide. The external sulfide source may be liquid, solid, or gas. Examples of materials that may cause sulfide stains are rubber, industrial fumes, foods, kraft paper, etc. This practice provides a means of estimating the relative susceptibility of plastic composition to sulfide staining.

1.1 This practice covers the determination of the resistance of plastics to staining in the presence of sulfides.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precaution statements, see Section 6.

Note 1—There is no known ISO equivalent to this standard.
