IEC 60247:2004 PDF

Scope: In this article, we have reviewed the temperature, the liquid-free material, the degradation factor, the relative power capacity, and the direct current power measurement method. This article mainly refers to liquids that have not yet been used for reference purposes, but may also be used for changing devices, electronics, and other electronic devices. However, this article is only suitable for use in South-eastern liquids, and the method described in this article is easy to use. The non-resilient compound is a complete liquid, and other cleaning methods are required.
