IEC 62812:2019规定了消除或减少不利现象影响的测量方法和相关试验条件，以提高低电阻测量的可实现精度。本文件中描述的方法适用于单个电阻器电阻的单独测量，也适用于作为试验顺序一部分的电阻测量。如果相关部件规范中有规定，或客户与制造商之间达成一致，则适用这些规范。

IEC 62812:2019 specifies methods of measurement and associated test conditions that eliminate or reduce the influence of adverse phenomena in order to improve the attainable accuracy of low-resistance measurements. The methods described in this document are applicable for the individual measurements of the resistance of individual resistors, and also for resistance measurements as part of a test sequence. They are applied if prescribed by a relevant component specification, or if agreed between a customer and a manufacturer.
