ASTM C67-2016 砖和粘土空心砖取样及测试方法 Standard Test Methods for Sampling and Testing Brick and Structural Clay Tile

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 These test methods include the following sections: Section Heading Section Scope 1 Referenced Documents 2 Terminology 3 Sampling 4 Specimen Preparation 5 Modulus of Rupture (Flexure Test) 6 Compressive Strength 7 Absorption 8 Freezing and Thawing 9 Initial Rate of Absorption (Suction) (Laboratory Test) 10 Efflorescence 11 Weight Per Unit Area 12 Measurement of Size 13 Measurement of Warpage 14 Measurement of Length Change 15 Initial Rate of Absorption (Suction) (Field Test) 16 Measurement of Void Area in Cored Units 17 Measurement of Void Area in Deep Frogged Units 18 Measurement of Out of Square 19 Measurement of Shell and Web Thickness 20 Breaking Load 21 Precision and Bias 22 Keywords 23 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.
