1.1 本指南提供了制定ASTM砌块规范的一般指南，该规范适用于使用当前ASTM标准中未包含的组成材料、制造方法及其组合制造的砌块。本指南不得解释为允许使用与适用建筑规范要求相冲突的产品。 1.2 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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。 1.3 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本指南旨在为制定非传统砌块的ASTM单元规范提供指导。鼓励本指南的用户查看 ASTM标准的形式和样式 以及参考装置规范和测试方法。请注意，并非本指南中的所有项目都必须适用于所有情况。 5.2 ASTM规范并非针对专利产品，而是针对多个制造商可以生产的一类产品，旨在确保使用这些组成材料或工艺的性能。因此，应避免仅与特定品牌相关的特定属性。 5.3 本指南未确定使用非传统材料制造的砌块可能需要考虑的全部因素。 传统砌块具有通常与砌体相关的固有特性，包括但不限于强度、耐火性、耐久性、热特性和声学特性。 5.4 当使用ASTM标准测试方法进行测试时，非传统砌块产品可能满足现有ASTM标准砌块规范的所有物理性能要求。然而，非传统砌块的性能无法得到保证，因为与传统砌块和组件相关的固有特性可能无法通过规范合规性测试进行具体评估。此外，符合现有装置规范中的物理特性并不意味着非传统装置符合这些规范，因为传统装置标准仅适用于使用该规范中定义的材料和工艺生产的装置（参见 附录X1 ).

1.1 This guide provides general guidance for developing ASTM unit specification for masonry units manufactured with constituent materials, manufacturing methods, and combinations thereof, that are not included in a current ASTM standard. This guide shall not be construed as permitting the use of a product conflicting with requirements of the governing building code. 1.2 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. 1.3 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. ====== Significance And Use ====== 5.1 This guide is intended to provide guidance for developing ASTM unit specifications for nontraditional masonry units. The user of this guide is encouraged to review the Form and Style for ASTM Standards as well as the referenced unit specifications and test methods. Note that not all items presented in this guide are necessarily applicable or appropriate in all cases. 5.2 ASTM specifications are not intended for proprietary products, but rather for a class of products that multiple manufacturers can produce, and are intended to ensure performance using those constituent materials or processes. Therefore, specific attributes that only relate to a specific brand should be avoided. 5.3 This guide does not identify the complete range of considerations that may be required for a masonry unit manufactured using a non-traditional material. Traditional masonry units possess intrinsic properties that are commonly associated with masonry including but not limited to strength, fire resistance, durability, thermal and acoustical attributes. 5.4 Non-traditional masonry unit products may meet all the physical property requirements of an existing ASTM standard unit specification, when tested using ASTM standard test methods. Nevertheless, performance of non-traditional masonry units is not assured since the intrinsic properties that are associated with traditional masonry units and assemblies may not be specifically evaluated through testing for specification compliance. Additionally, compliance with the physical properties in existing unit specifications does not mean that non-traditional units are in compliance with those specifications as traditional unit standards are only applicable to units produced with those materials and processes defined within that specification (refer to Appendix X1 ).
