紧固件.扭矩/夹持力试验 ISO 16047-2005

[中文适用范围]： 本标准规定了对螺纹紧固件及相关零件进行扭矩/夹紧力试验的条件。 它基本上适用于由碳钢和合金钢制成的螺栓、螺钉、螺柱和螺母，其机械性能在ISO中规定。 898-1 ISO 898-2 具有螺纹尺寸 M3 至 M39 的 ISO 公制螺纹。 它也适用于根据 ISO 68-1 具有三角形 ISO 螺纹的其他外螺纹和内螺纹紧固件的组合。 它不适用于不受拉应力的紧定螺钉和类似螺纹紧固件，也不适用于形成其自身形状的螺钉。 自己的配合线程。 除非其他 [外文原描述]： ISO 16047:2005 specifies the conditions for carrying out torque/clamp force tests on threaded fasteners and related parts. It is applicable, basically, to bolts, screws, studs and nuts made of carbon steel and alloy steel, whose mechanical properties are specified in ISO 898-1, ISO 898-2 or ISO 898-6, having ISO metric threads with thread sizes M3 to M39. It is also applicable to the combination of other externally and internally threaded fasteners with a triangular ISO thread according to ISO 68. It is not applicable to set screws and similar threaded fasteners that are not under tensile stresses, nor to screws which form their own mating thread or threaded fasteners having additional self-locking features.
