标准摘要
[中文适用范围]： IEC 61298-2:2026规定了过程测量仪表（除由IEC 62828系列标准规范的流程测量变送器，PMT）功能与性能特性的测试方法及程序，包括测试报告的编写要求。该标准适用于具有特定输入与输出变量，以及输入与输出之间特定关系（传递函数）的上述各类设备，涵盖模拟与数字设备。对于需要特殊测试的设备，本标准可与规定特殊测试的产品专用标准配合使用。本文件涵盖在参考条件下进行的测试。第三版取代并废止了2008年发布的第二版，属于技术修订版。相较于上一版，本次修订包含以下重大技术变更：a) 流程测量变送器（PMT）已从本标准适用范围中移除。 [外文原描述]： IEC 61298-2:2026 specifies general methods and procedures for conducting tests and reporting on the functional and performance characteristics of process instrumentation except process measurement transmitters (PMT) which are standardized by IEC 62828 series. The tests are applicable to any such devices characterized by their own specific input and output variables, and by the specific relationship (transfer function) between the inputs and outputs and include analogue and digital devices. For devices that require special tests, this standard can be used, together with any product specific standard specifying special tests. This document covers tests made under reference conditions. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Process measurement transmitters (PMT) have been removed from the scope of this standard
