These test methods cover procedures for the sampling and testing of brick and structural clay tile. The tests include modulus of rupture, compressive strength, absorption, saturation coefficient, effect of freezing and thawing, efflorescence, initial rate or absorption, and determination of weight, size, warpage, length chanange, and void areas. For purposes of these tests, full-size bricks, tiles, or solid masonry units shall be used as test specimens. They shall be representative of the lot of units from which they are to be selected in respect of the range of colors, textures, and sizes and shall be free of or brushed to remove dirt, mud, mortar, or other foreign materials unassociated with the manufacturing process.
