IEC 61003-2:20 16为具有双位置或多位置输出的电气和气动仪器的检查和常规测试提供了指南，例如用于验收测试或维修后。它适用于电气和气动工业过程仪表，使用连续信号的测量值。设定点值可以是机械(位置、力等)或标准信号。这些仪器可以用作控制器或开关，用于警报和其他类似目的。第二版取消并取代了2009年出版的第一版。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: -使用术语“双位置或多位置输出”而不是“双位置输出”或多国文书”（见范围）； -使用术语“差动间隙”而不是“开关差动”(参见表1第2号)； -使用术语“介电强度”而不是“隔离测试”（参见表1第5号）。 本出版物应与IEC 61003-1:20 16、IEC 61298-2:20 08和IEC 61298-3:20 08一并阅读

IEC 61003-2:2016 gives guidelines for inspection and routine testing of electrical and pneumatic instruments with two- or multi-position output, for instance, for acceptance tests or after repair. It is applicable to electrical and pneumatic industrial-process instruments, using measured values that are continuous signals. The set point value may be either a mechanical (position, force, etc.) or a standard signal. These instruments may be used as controllers or as switches for alarms and other similar purposes. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- use of the term "two- or multi-position output" instead of "two- or multi-state instrument" (see Scope);
- use of the term "differential gap" instead of "switching differential" (see Table 1 No 2);
- use of the term "dielectric strength" instead of "isolation test" (see Table 1 No 5).

This publication is to be read in conjunction with IEC 61003-1:2016, IEC 61298-2:2008 and IEC 61298-3:2008
