1.1 本规范涵盖了适用于一般工程应用的标称直径M01至M36的碳钢和合金钢公制铆钉的九个性能等级的化学和机械要求。 1.2 本规范不包括任何性能等级铆钉的尺寸要求。出于采购目的参考本规范时，必须额外指定产品的尺寸、类型、样式和任何特殊尺寸。 1.2.1 如果要求有任何冲突，则单个产品规范的要求应优先于本通用规范的要求。 1.2.2 买方可规定附加要求，但不得否定本通用规范或单个产品规范的任何规定。此类附加要求必须包含在订单信息中（见第节 3. ). 1.3 经买方同意，当订购4.6或4.8级时，可以提供5.8级紧固件；订购4.6级时，可提供4.8级； 1.4 每个属性类别适用的产品尺寸范围见 表1 化学成分要求和机械要求表（见 表2 ). 1.5 附录X1 解释了属性类指定数字的意义。 1.6 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 chemical and mechanical requirements for nine property classes of carbon and alloy steel metric rivets in nominal diameters M01 through M36 suited for use in general engineering applications. 1.2 This specification does not cover dimensional requirements for rivets of any property class. When referencing this specification for procurement purposes, it is mandatory that size, type, style, and any special dimensions of the product be additionally specified. 1.2.1 In case of any conflict in requirements, the requirements of the individual product specification shall take precedence over those of this general specification. 1.2.2 The purchaser may specify additional requirements which do not negate any of the provisions of this general specification or of the individual product specification. Such additional requirements, the acceptance of which are subject to negotiation with the supplier, must be included in the order information (see Section 3 ). 1.3 When agreed on by the purchaser, Class 5.8 fasteners may be supplied when either Classes 4.6 or 4.8 are ordered; Class 4.8 may be supplied when Class 4.6 is ordered; 1.4 The product size range for which each property class is applicable is given in Table 1 on chemical composition requirements, and the mechanical requirements table (see Table 2 ). 1.5 Appendix X1 explains the significance of the property class designation numerals. 1.6 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.
