Anotace textu normy ASTM C279-23 :

This specification covers chemical-resistant masonry units, specifically, solid kiln fired bricks and tiles made from clay, shale, or mixtures thereof, suitable for indoor and outdoor use in masonry construction subjected to chemical environments. The bricks and tiles are considered to be of three types as follows: Type I, for use where low absorption and high acid resistance are not major factors; Type II, for use where lower absorption and higher acid resistance are required; and Type III, for use where minimum absorption and maximum acid resistance are required. The masonry units shall undergo tests and adhere accordingly to the following physical and chemical requirements: water absorption, warpage, surface texture, size and dimension, flexural strength, modulus of rupture, sulfuric acid solubility, and percent weight loss.
