1.1 本规范涵盖了由粘土、页岩或其混合物制成的实心窑烧砖，适用于与工业烟囱中烟气中存在的化学物质接触的砌体结构。 1.2 本文所涵盖的砖和瓷砖旨在用于恶劣的化学环境中，在这些环境中可能需要考虑抗热震性。这些砖通常与耐化学腐蚀的砂浆一起使用。 1.3 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.4 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。 1.5 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 This specification covers solid kiln fired brick made from clay, shale, or mixtures thereof suitable for use in masonry construction in contact with the chemicals present in flue gases found in industrial chimneys. 1.2 The brick and tile covered herein are intended for use in harsh chemical environments where resistance to thermal shock may be a consideration. These brick are normally used with chemical-resistant mortars. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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.
