标准范围

IEC 60051-2:20 18适用于具有模拟显示器的直接作用指示电流表和电压表。它还适用于:？刻度标记不直接对应于其电输入量的直接作用指示电流表和电压表，前提是它们之间的关系是已知的；？直接作用指示电流表和电压表以及在其测量和/或辅助电路中具有电子设备的附件。本文件不适用于:？其自身IEC标准涵盖的特殊用途仪器；？用作附件时受其自身IEC标准保护的特殊用途设备。IEC 60051-2:20 18取消并取代了1984年发布的第四版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:A）？根据新版IEC 60051-1和IEC 60051-9更新内容；b）？增加附录A，规定供试品的不合格分类。本国际标准将与IEC一起使用？60051-1:2016.

IEC 60051-2:2018 applies to direct acting indicating ammeters and voltmeters having an analogue display.
It also applies to:
？direct acting indicating ammeters and voltmeters whose scale marks do not correspond directly to their electrical input quantity, provided that the relationship between them is known;
？direct acting indicating ammeters and voltmeters and accessories having electronic devices in their measuring and/or auxiliary circuits.
This document does not apply to:
？special purpose instruments which are covered by their own IEC standards;
？special purpose devices which are covered by their own IEC standards when they are used as accessories.
IEC 60051-2:2018 cancels and replaces the fourth edition published in 1984. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a)？updating of content in line with new editions of IEC 60051-1 and IEC 60051-9;
b)？addition of Annex A to specify the nonconformity classification of test item.
This International Standard is to be used in conjunction with IEC？60051-1:2016.
