1.1 本指南旨在评估和描述商业应用中使用的石灰窑粉尘和硅酸盐水泥窑粉尘。本指南不适用于石灰或硅酸盐水泥。 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。 1.3 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。 ====意义和用途====== 4.1 本指南提供了石灰窑粉尘和硅酸盐水泥窑粉尘的应用和适当的测试程序列表，以确定其选定用途。 4.2 本指南涵盖的石灰窑粉尘和硅酸盐水泥窑粉尘的成分可能因来源而异。因此，建议只有在对此类产品的具体成分、物理性能、性能特征和预期变化进行了评估后，才能使用此类产品。在确定一个或多个尘源的可变性之前，建议经常进行性能测试。 4.3 应编制规范，以便于负责人的使用、环境保护和工程设计。

1.1 This guide is intended to evaluate and describe lime kiln dusts and portland cement kiln dusts for use in commercial applications. This guide is not intended to cover uses for lime or portland cement. 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 ====== 4.1 This guide provides a list of applications and appropriate test procedures to establish selected uses for the lime kiln dusts and portland cement kiln dusts. 4.2 The lime kiln dusts and portland cement kiln dusts covered by this guide may vary in composition from one source to another. It is therefore advised that the use of such products be undertaken only after their specific compositions, physical properties, performance characteristics, and the anticipated variabilities have been evaluated for the service intended. Until the degree of variability in the dust source or sources has been established, frequent performance testing is recommended. 4.3 Specifications should be prepared to facilitate uses, environmental protection, and engineering designs by the responsible persons.
