1.1 本规范涵盖离心式和轴流式风机和鼓风机，其气流部件由耐腐蚀的纤维增强热固性塑料（FRP）制成。内部结构可以包括封装的金属紧固装置、轮毂和轴。 1.2 如果生产的风机和鼓风机符合本规范的所有要求，则可在制造过程中使用纤维玻璃以外的增强材料。 1.3 本规范中使用的术语“风机”包括离心式和轴向式风机和鼓风机。 1.4 本规范旨在为FRP风机的购买者、系统设计师、规范制定者和供应商提供风机施工的最低标准以及确定安全运行速度的通用依据。 1.5 以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 注1: 没有已知的ISO等效于本标准。 注2: 附录X2 包含风扇系统设计师可能感兴趣的文档列表。 1.6 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。 1.7 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。

1.1 This specification covers centrifugal and axial fans and blowers with airstream components fabricated of fiber-reinforced thermoset plastics (FRP) for corrosion resistance. It is acceptable for internal structures to include encapsulated metal fastening devices, hubs, and shafts. 1.2 Reinforcing materials other than fibrous glass are acceptable for use in the fabrication, provided the fans and blowers produced meet all the requirements of this specification. 1.3 The term “fans” as used in this specification includes fans and blowers, both centrifugal and axial. 1.4 The purpose of this specification is to provide purchasers, system designers, specifiers, and suppliers of FRP fans with minimum standards for fan construction and a common basis for determining safe operating speeds. 1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only. Note 1: There is no known ISO equivalent to this standard. Note 2: Appendix X2 contains a list of documents potentially of interest to designers of fan systems. 1.6 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. 1.7 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.
