用于螺纹紧固件的旋转工具 脉冲式和脉冲式工具 性能测试方法

[中文适用范围]： 本文件规定了在实验室环境中用于安装螺纹紧固件的液压脉冲工具和电动脉冲工具以及动力装配工具（本文中统称为“工具”）的实验室性能测试方法。它提供了测试程序、待测性能参数以及如何评估和呈现测试数据的说明。 它还提供了一种测量扭矩重复性（离散度）的方法： — 在本文件规定的扭矩率范围内； — 在制造商定义的扭矩调节范围内。 它提供了设备参数、测试内容以及如何评估和呈现测试数据的说明。 它适用于： — 任何动力源的工具，例如气动或电动（包括电池供电）； — 以不连续增量施加扭矩的工具； — 扭矩范围在0.5 N·m至800 N·m内的工具。超出此范围，可修改测试方法，但修改需记录在测试报告中。 它不适用于： — 冲击扳手； — 棘轮扳手或带有棘轮离合器的扳手。 附录A评述了扭矩测量与基于夹紧力测试之间的关系。 附录B讨论了使用电机不连续操作来提供扭矩脉冲的工具。 它要求制造商在其定义的工具扭矩范围内进行测试；但是，它允许用户进行单点测试，以最大程度减少在广泛测试扭矩水平下所需的测试接头数量。附录C提供了推荐的测试扭矩水平列表。 [外文原描述]： This document specifies a laboratory performance test method for hydraulic impulse and electric impulsing tools for installing threaded fasteners in a laboratory environment, and for power assembly tools (referred throughout the document as “tools”) for installing threaded fasteners. It gives instructions on the procedure, performance parameters to test and how to evaluate and present the test data. It also provides a method for the measurement of torque repeatability (scatter) over a range of torque rates as specified in this document, and over a range of torque adjustment as defined by the manufacturer. It gives instructions on equipment parameters, what to test for and how to evaluate and present the test data. It is applicable to tools of any power source, such as pneumatic or electric, including battery-powered, which apply torque in discontinuous increments, and within the torque range 0,5 N·m to 800 N·m. Outside this range, it is acceptable to modify the test method providing that the modification is documented in the test report. It is not applicable to impact wrenches, and ratchet wrenches or wrenches with ratcheting clutches. The relationship between torque measurements and clamp force-based tests is commented on in Annex A . The use of tools using discontinuous operation of the motor to provide torque impulses is discussed in Annex B . It requires manufacturers to perform tests over their defined torque range of the tool; however, it allows users to perform single point tests in order to minimize the number of test joints necessary for a wide range of test torque levels. A list of preferred test torque levels is provided in Annex C .
