ISO 16047 specifies the conditions for carrying out torque/clamp force tests on threadedfasteners and related parts
本国际标准详细地阐述了实施螺纹紧固件和相关零件的紧固扭矩一轴向预紧力试验的条件。
lt is applicable，basically，to bolts，screws，studs and nuts made of carbon steel and alloy steel，whosemechanical properties are specified in ISO 898-1，ISO 898-2 or ISO 898-6，having IS0 metric threads withthread sizes M3 to M39.It is also applicable to the combination of other externally and internally threadedfasteners with a triangular ISO thread according to ISO 68-1.
本标准主要适用于机械性能符合ISO 898-1、ISO 898-2或ISO 898-6，螺纹符合ISO米制螺纹，螺纹规格为M3到M39的碳钢及合金钢制造的螺栓、螺钉、螺柱和螺母。本标准也适用于具有符合ISO68-1的米制三角形螺纹的其他外螺纹和内螺纹的紧固件。
lt is not applicable to set screws and similar threaded fasteners that are not under tensile stresses，nor to screwswhich form their own mating thread or threaded fasteners having additional self-locking features
本标准不适用于不承受拉力载荷的紧定螺钉及类似的螺纹紧固件，也不适合自攻螺钉和有自锁功能特性的螺纹紧固件。
Unless otherwise agreed，the tests are carried out at room temperature. However，tests carried out understandard conditions are made at a temperature of 10℃ to 35℃
若无其他特殊的协议规定，试验应在10℃到35℃的室温下进行。
This method allows determination of the tightening characteristics of threaded fasteners and related parts本标准规定的试验方法可以测定紧固件和相关零件的紧固特性。
