标准范围

取消并替换第一版（1988年）。规定了在+10°C至+35°C的环境温度范围内进行试验时，具有规定验证载荷值的螺母的机械性能。适用于标称螺纹直径为8 mm至39 mm的三角形ISO螺纹螺母，直径/节距组合符合ISO 261，螺纹公差为6H符合ISO 965-1和965-2，有特定机械要求，扁钢宽度符合ISO 272规定，标称高度大于或等于0.5d，由碳钢或合金钢制成。不适用于要求特殊性能的螺母，如焊接性、主要扭矩性能、耐腐蚀性、承受+300°C或以下温度的能力-50摄氏度。

Cancels and replaces the first edition (1988). Specifies the mechanical properties of nuts with specified proof load values when tested at an ambient temperature range of +10 °C to +35 °C. Applies to nuts with nominal thread diameters from 8 mm up to and including 39 mm, of triangular ISO thread, with diameter/pitch combinations in accordance with ISO 261, with thread tolerances 6H in accordance with ISO 965-1 and 965-2, with specific mechanical requirements, with widths across flats as specified in ISO 272, with nominal heights greater than or equal to 0,5d, made of carbon steel or alloy steel. Does not apply to nuts requiring special properties as weldability, prevailing torque performance, corrosion resistance, ability to withstand temperatures above +300 °C or below -50 °C.
