电工产品的质量主要包括外观、性能和可靠性三个方面。可靠性也是一种性能,由于我们的电工产品,除个别外,还都没有这方面的要求,并且可靠性又是一个新概念,所以,把它同其他一些我们熟悉的性能,例如使用性能、运行性能、环境适应性能、安全性能等分别开来。当然,产品在技术上的统一程度如何,零部件的通用程度如何,产品的互换性如何等,在一定意义上来说,也是产品的质量;很难想象,基本参数、型式尺寸不符合标准的产品,胡乱标注符号、标记的产品,能说是好产品
The quality of electrical products mainly includes three aspects: appearance, performance and reliability. Reliability is also a performance, because our electrical products, in addition to individual, there are no requirements in this regard, and reliability is a new concept, so it is with other properties that we are familiar with, such as performance, Operational performance, environmental adaptation performance, and safety performance are separately provided. Of course, the degree of product’s technical harmonization, the general degree of parts and components, and the interchangeability of products are, in a certain sense, also the quality of the product; it is difficult to imagine that the basic parameters and type sizes do not meet the standards. Products, products that are marked with symbols, marked, can be said to be good products
