The applicability to deaired brick of the durability gradings in the current American Society for Testing Materials Specifications C 62 and C 216 was questioned because of the lack of data on the properties and weathering resistance of de‐aired brick. The production of 14 plants producing deaired brick was accordingly sampled, and determinations were made on representative subsamples of such properties as transverse and compressive strength, water absorptions by 24‐hr, cold immersion and by 5‐hr, boiling, and the derived saturation coefficients. Representative subsamples were also subjected to the action of weather in the exposure test plot maintained at the National Bureau of Standards and relations between measured properties and the effect of weathering for five years were considered. The effect of lamination and other types of nonhomo‐geneity on weathering was also noted. It was concluded that the current specifications apply to both deaired and nondeaired brick.
