标准摘要
[中文适用范围]： IEC 61298-2:2026 RLV 版本同时包含国际电工委员会（IEC）国际标准正式文本及其修订对照版本。修订对照版仅提供英文版，便于用户快速、便捷地比对正式标准与其上一版本之间的全部变更内容。 IEC 61298-2:2026 标准规定了过程仪表（过程测量变送器（PMT）除外，其由 IEC 62828 系列标准规范）的功能特性和性能特性的测试方法及报告要求。该标准适用于各类具有特定输入与输出变量、以及输入输出之间特定关系（即传递函数）的此类设备，涵盖模拟和数字型设备。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联合使用。 本文件所规定的测试均在参考条件下进行。本第三版取代并废止了 2008 年发布的第二版，属于技术性修订。相较于上一版本，本次修订包含以下重大技术变更：a) 已将过程测量变送器（PMT）从本标准适用范围中移除。 [外文原描述]： IEC 61298-2:2026 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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
