Standard Specification for Steel Springs, Helical, Heat-Treated 热处理螺旋形钢弹簧的标准规范
发布日期: 2024-10-15
1.1 本规范涵盖由热锻圆钢棒制成的带锥形、封闭、方形和接地端的热卷、热处理螺旋压缩弹簧 3 / 8 在。(9.5毫米)和更大的直径。 1.2 本规范还用于告知用户适用于中所述弹簧类型的实际制造限制、机械试验和检验要求 1.1 . 1.3 提供了可选性质的补充要求S1至S8。它们仅在买方指定时适用。这些补充要求的细节应由制造商和买方商定。 1.4 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换,仅供参考,不被视为标准。1.5 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》中确立的国际公认的标准化原则制定的。
1.1 This specification covers hot-coiled, heat-treated helical compression springs with tapered, closed, squared and ground ends made of hot-wrought round steel bars 3 / 8 in. (9.5 mm) and larger in diameter. 1.2 This specification also serves to inform the user of practical manufacturing limits, mechanical tests, and inspection requirements applicable to the type of spring described in 1.1 . 1.3 Supplementary Requirements S1 to S8 inclusive of an optional nature are provided. They shall apply only when specified by the purchaser. Details of these supplementary requirements shall be agreed upon by the manufacturer and purchaser. 1.4 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. 1.5 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.
