The C1670 - 14 Standard Specification for Adhered Manufactured Stone Masonry Veneer Units has been revised. According to the abstract:

This specification establishes the minimum product requirements for adhered manufactured stone masonry veneer (AMSMV) units which are manufactured from cementitious materials, aggregates, air-entraining admixtures, concrete admixtures, coloring pigments, reinforcement fibers, and other components which are wet-cast into shapes simulating the appearance of stone, rocks found in nature, and other textures. It also addresses sampling, physical properties and testing, finish and appearance, product identification and packaging, and reporting.

The updated standard is available for purchase from ASTM in either a hard copy or PDF format. Read More
