工业发展到大生产和分工阶段,标准化是这一阶段的必然结果。标准化工作从互换性开始,逐步形成了产品标准、检验方法标准、质量标准、工艺标准、操作标准、直到产生许可证制度,最终目的就是要在生产上推行全面质量控制。当前世界先进工业国家的标准化工作发展得很迅速,这些工作对专业化生产和产品在市场的竞争,起到了极大的促进作用。热处理是机械制造工艺中的重要组成部分,也是保证产品质量的一个重要环节,但是,热处理专业标准化还是一项比较新的工作,世界先进工业国家虽然在50年代开始,
Industrial development to the stage of large-scale production and division of labor, standardization is the inevitable result of this stage. Standardization starts with interchangeability, gradually forming product standards, inspection method standards, quality standards, process standards, operating standards, until the creation of a licensing system, the ultimate goal is to implement a comprehensive quality control in production. The standardization work in the world’s advanced industrial countries has developed rapidly. These efforts have played a significant role in promoting professional production and product competition in the market. Heat treatment is an important part of the mechanical manufacturing process and an important part of ensuring product quality. However, the standardization of heat treatment is still a relatively new job. Although the world’s advanced industrial countries began in the 1950s,
