一、概述冶金工业部颁布的YB53-64《金属维氏硬度试验方法》在国内已执行近20年。这些年中,在产品质量检验方面起了很大作用,然而在执行过程中也表现出了某些不足之处。特别是随着生产和科学技术的发展,该标准已不能满足需要。因而制定统一的国家标准是非常必要的。在制定新的国家标准时,收集了生产及科研单位对执行YB53-64的意见,并广泛征求了对制定国家标准的要求和建议。同时参
I. Overview YB53-64 “Metal Vickers Hardness Test Method” promulgated by the Ministry of Metallurgical Industry has been implemented in China for nearly 20 years. In these years, it has played a very important role in product quality inspection. However, some shortcomings were shown in the implementation process. Especially with the development of production and science and technology, the standard can no longer meet the needs. Therefore, the development of a unified national standard is very necessary. In formulating new national standards, the opinions of the production and research institutes on the implementation of YB53-64 were collected, and the requirements and suggestions for the formulation of national standards were extensively solicited.
