为使各有关计量部门、生产厂的检定人员正确理解和准确执行《橡胶、塑料拉力试验机》检定规程(JJG588—89),有必要将规程内容加以说明,供有关人员参考。规程首先在引言中对受检的橡胶、塑料拉力试验机(以下简称拉力机)的测量上限作了不大于100kN的定量规定。因此对规格大于100kN的同类拉力机可参照本规程进行检定。另外,规程概述中提示了拉力机可借助各种夹具,供橡胶、塑料试样进行压缩,抗弯及其它项目的试验。需要注意的是进行附加试验所用的夹具应符合有关试验方法的规定,试验负荷必须在拉力机的测量范围内才有效。如果试验
In order to correctly understand and accurately carry out the test procedures of Rubber and Plastic Tensile Testing Machine (JJG588-89) by all relevant departments of measurement and verification of production plants, it is necessary to explain the contents of the procedures for the reference of relevant personnel. Procedures First of all in the introduction of the rubber, plastic tensile testing machine (hereinafter referred to as Rally) made the upper limit of not more than 100kN quantitative requirements. Therefore, specifications of more than 100kN similar Rally machine can be tested in accordance with this regulation. In addition, the procedure outlined in the instructions Rally machine with a variety of fixtures for rubber, plastic samples for compression, bending and other projects of the test. It should be noted that the fixture used for the additional test should comply with the relevant test methods, the test load must be effective within the measuring range of the tensile testing machine. If test
