1.1 这些试验方法包括砖和结构粘土砖的取样和试验程序。虽然不一定适用于所有类型的单元，但测试包括断裂模量、抗压强度、吸收、饱和系数、冻融效应、风化、初始吸收率以及重量、尺寸、翘曲、长度变化和空隙面积的测定。（与陶瓷釉相关的其他测试方法包括不渗透性、耐化学性、不透明度和耐龟裂性。 1.2 本标准的文本引用了提供解释材料的注释和脚注。这些注释和脚注（不包括表和图中的注释和脚注）不应被视为本标准的要求。 注1: 执行该测试方法的测试实验室应根据实践进行评估 1093年 。 1.3 以国际单位制或英寸表示的数值- 磅单位应单独视为标准。每个系统中规定的值不一定是完全相等的；因此，为了确保符合标准，每个系统应独立使用，并且两个系统的值不得合并。 1.4 这些测试方法包括以下部分: 章节标题 部分 范围 1. 参考文件 2. 术语 3. 取样 4. 试样制备 5. 断裂模量（弯曲试验） 6. 抗压强度 7. 吸收 8. 冷冻和解冻 9 初始吸收率（吸入）（实验室试验） 10 渗出 11 单位面积重量 12 尺寸的测量 13 翘曲的测量 14 长度变化的测量 15 初始吸收率（吸入）（现场试验） 16 取芯单元空隙面积的测量 17 深蛙式单元空隙面积的测量 18 误差的测量 19 壳体和腹板厚度的测量 20 断裂载荷 21 （Ceramin釉）不透水性试验 22 耐化学性试验（陶瓷釉） 23 （陶瓷釉的）蒸压Crazing试验 24 （陶瓷釉）不透明度试验 25 精度和偏差 26 关键词 27 高压釜设备和操作的安全注意事项 附录X1 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

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 glazes include imperviousness, chemical resistance, opacity, and resistance to crazing. 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 either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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 Imperviousness Test (of Ceramin Glazes) 22 Chemical Resistance Test (of Ceramic Glazes) 23 Autoclaved Crazing Test (of Ceramic Glazes) 24 Opacity Test (of Ceramic Glazes) 25 Precision and Bias 26 Keywords 27 Safety Precautions for Autoclave Equipment and Operation Appendix X1 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
