硬度,作为材料机械特性的代用特性,现正被广泛地使用着。为此,作为质量管理用,在一部分领域里,与通常测定条件不同的测定方法也就实行起来了。但是,象那样应用的试验或硬度计,还必须掌握他的基础事项,即以 JIS 标准等为依据的试验和其测定值的关联性。现把与硬度有关的15种 JIS 标准用表1表示,当前对 JIS 标准的重新评定工作,正在积极地进行着。另外,ISO 标准也从以前的材料领域类别 TC Hardness, which is now widely used as a substitute for the mechanical properties of materials. For this reason, the measurement methods different from the usual measurement conditions are practiced in some areas for quality control. However, a test or a durometer to be applied as such must also grasp his basic items, that is, the correlation between the test based on the JIS standard and the like and the measured value thereof. Now, 15 types of JIS standards related to hardness are shown in Table 1, and the current re-evaluation of the JIS standards is being actively carried out. In addition, the ISO standard is also from the previous material field category TC
