Formerly under the jurisdiction of Committee C03 on Chemical-Resistant Nonmetallic Materials, this practice was withdrawn in January 2021 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

This practice covers detailed information on the handling, installation, and proper use of chemical-resistant sulfur mortar. The sulfur mortar shall be stored in unopened containers and in a clean, dry place to prevent contamination of the product. Sulfur mortar must be heated and molten in order to be used. Adequate ventilation should be provided whether sulfur mortars are used. All surfaces which molten sulfur mortar will contact must be dry to prevent splattering. Horizontal joints may be formed by resting each brick or tile on three spacers which are placed in a triangular pattern. The floor shall be given a skim coat of sulfur mortar prior to installing brick or tile. The chemical resistance of sulfur mortars shall be determined.

1.1 This practice provides detailed information on the handling, installation, and proper use of chemical-resistant sulfur mortar such as those covered in Specification C287.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 safety precautions, see Section 5.
