1. Scope*
1.1 These test methods cover procedures for the sampling and testing of brick and structural clay tile.Although not necessarily
applicable to all types of units, tests include modulus of rupture, compressive strength, absorption, saturation coefficient, effect of
freezing and thawing, efflorescence, initial rate of absorption and determination of weight, size, warpage, length change, and void
area. (Additional methods of test pertinent to ceramic glazed facing tile are included in Specification C126.)
1.2 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered as requirements of the standard.
NOTE 1—The testing laboratory performing this test method should be evaluated in accordance with Practice C1093.
1.3 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.
1.4 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.

from which they are selected and shall include specimens representative of the complete range of colors, textures, and sizes.
Specimens shall be free of or brushed to remove dirt, mud, mortar, or other foreign materials unassociated with the manufacturing
process. Brushes used to remove foreign material shall have bristles of plastic (polymer) or horsehair. Wire brushes shall not be
