标准摘要
[中文适用范围]: 本文件规定了非合金钢或合金钢制成的螺母在10℃至35℃环境温度范围内测试时的机械和物理性能。 本文件适用于螺母: ——带 ISO 公制螺纹(参见 ISO 68-1), — 带符合 ISO 261 和 ISO 262 的直径/螺距组合, — 带粗牙螺纹 M5 至 M39,以及细牙螺纹 M8×1 至M39×3, — 螺纹公差符合 ISO 965-1、ISO 965-2 或 ISO 965-5, — 指定性能等级 04、05、5、6、8、10 和 12,包括验证载荷, — 三个不同的螺母样式(见 5.1):普通螺母(样式 1)、高螺母(样式 2)和薄螺母(样式 0), — 最小外径或对边宽度 s ≥ 1.45D, — 能够与螺栓配合,螺钉和螺柱的性能等级符合 ISO 898-1(见附录 B),并且 — 预期用于 –50 °C 至 +150 °C 或高达 +300 °C 的应用。 警告 — 符合本文件要求的螺母在 10 °C 至 35 °C 的环境温度范围内进行测试,并用于 –50 °C 至 +150 °C 的应用;然而,对于特定应用,这些螺母也可以在此范围之外使用,最高可达 +300 °C。 它们可能在较低和/或升高的温度下不保留指定的机械和物理性能。 因此,用户有责任根据组件的使用环境条件确定适当的选择(另见7.1)。 有关适用于热浸镀锌螺母的其他规范,请参阅 ISO 10684。 对于为特定应用而设计的螺母,请参阅 ISO/TR 16224。 本文件未规定功能特性的要求,例如: ——现行扭矩特性(参见 ISO 2320), —扭矩/夹紧力性能(测试方法参见 ISO 16047), — 可焊性,或 — 耐腐蚀性。 1 [外文原描述]: This document specifies the mechanical and physical properties of nuts made of non-alloy steel or alloy steel, when tested at the ambient temperature range of 10 °C to 35 °C. This document applies to nuts: — with ISO metric thread (see ISO 68-1), — with diameter/pitch combinations according to ISO 261 and ISO 262, — with coarse pitch thread M5 to M39, and fine pitch thread M8×1 to M39×3, — with thread tolerances according to ISO 965-1, ISO 965-2 or ISO 965-5, — with specified property classes 04, 05, 5, 6, 8, 10 and 12 including proof load, — of three different nut styles (see 5.1): regular nuts (style 1), high nuts (style 2) and thin nuts (style 0), — with a minimum outside diameter or width across flats s ≥ 1,45 D , — able to mate with bolts, screws and studs with property classes in accordance with ISO 898-1 (see Annex B), and — intended to be used in applications ranging from –50 °C to +150 °C, or up to +300 °C. WARNING — Nuts conforming to the requirements of this document are tested at the ambient temperature range of 10 °C to 35 °C and are used in applications ranging from –50 °C to +150 °C; however, these nuts are also used outside this range and up to +300 °C for specific applications. It is possible that they do not retain the specified mechanical and physical properties at lower and/or elevated temperatures. Therefore, it is the responsibility of the user to determine the appropriate choices based on the service environment conditions of the assembly (see also 7.1). For additional specifications applicable to hot dip galvanized nuts, see ISO 10684. For nuts designed for particular applications, see ISO/TR 16224. This document does not specify requirements for functional properties such as: — prevailing torque properties (see ISO 2320), — torque/clamp force properties (see ISO 16047 for test method), — weldability, or — corrosion resistance.
