工业过程控制系统 带气动输出的阀门定位器性能评定方法

[中文适用范围]： IEC 61514:2026 RLV 版本包含正式的 IEC 国际标准及其红行修订版。红行修订版仅提供英文版本，便于用户快速、便捷地对照正式 IEC 标准与其上一版本之间的所有修订内容。 IEC 61514:2026 规定了用于评估单作用或双作用模拟式定位器静态与动态性能测试方法。该标准适用于接收标准模拟输入信号（参见 IEC 60381-1、IEC 60381-2 及 IEC 60382）并具有气动输出信号的定位器。采用脉冲信号或数字信号输入的定位器、带数字控制器的定位器以及输出为脉冲信号的定位器，均不属于本文件适用范围。 测试可在定位器单独进行（不与执行机构连接），也可将定位器与特定执行机构连接后作为一个整体进行。文中已明确说明不同情况所需的测试方式。 本文件所述评估方法旨在供制造商用于评定其产品性能，同时供用户或独立检测机构用于验证制造商所声明的性能指标。在测试过程中，评估机构与制造商之间保持密切沟通至关重要；制造商有权根据其仪器规格对测试方案提出意见，并对测试方案及结果进行评论。 本文件旨在提供定位器元件、作用方式及特性定义，规定统一方法以测量性能误差及影响因素对特性产生的影响，并描述如何报告及评估所获取的测量数据结果。 文中所述的试验条件（例如环境温度范围、供电电源等）均基于实际使用中的常见工况。因此，在制造商或用户未另行指定数值时，应采用本文件规定的数值；若采用其他数值，应在报告中明确说明。 应当明确，制造商所规定的产品规格及安装、操作说明在整个测试过程中均适用。本文件所规定的测试项目未必适用于专为极端恶劣环境设计的仪器；反之，对于仅需在较有限工况下运行的仪器，可酌情减少测试项目，仍可满足评估要求。 当无需或无法按本文件进行全面评估时，仅需执行相关测试项目，并依据本文件相应部分报告测试结果。在此类情况下，测试报告中应明确说明该报告未涵盖本文件规定的全部测试项目。 本第二版于 2026 年发布，取代 2000 年发布的首版，属于技术修订版。 相对于上一版，本版包含以下主要技术变更： a) 在第 6.6.8 条及表 5 中，磁场强度要求由 100 A/m 调整为均方根值 30 A/m； b) 第 6.10.4 条及图 9 已修改，以提升表述的清晰性与可读性； c) 第 7.4 条中删除了对 IEC 61187 的引用，并新增表 4，标题为“文件信息”。 [外文原描述]： IEC 61514:2026 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 61514:2026 specifies tests designed to determine the static and dynamic performance of single-acting or double-acting analogue positioners. The tests apply to positioners which receive standard analogue input signals (as specified in IEC 60381-1, IEC 60381-2 and IEC 60382) and have a pneumatic output. Positioners with pulsed or digital input signals, positioners with digital controllers and positioners with pulsed outputs are outside the scope of this document. Testing is conducted either on a positioner alone, independently of an actuator, or on a positioner mounted and connected to a specific actuator, as a combined unit. The text makes clear where different approaches are required. The methods of evaluation given in this document are intended for use by manufacturers to determine the performance of their products, and by users, or independent testing establishments, to verify manufacturers' performance specifications. The closest liaison between the evaluating body and the manufacturer is indispensable during the tests, including the possibility for the manufacturer to influence the test programme based on the manufacturer's specifications for the instrument and comment on both the test programme and the results. This document is intended to provide definitions of positioner elements, actions, and characteristics, to specify uniform methods of measuring performance errors and effects of influence quantities on those characteristics, and to describe methods of reporting and evaluating the results of the measurement data obtained. The test conditions described in this publication (for example range of ambient temperatures and power supply) relate to conditions which commonly arise in use. Consequently, the values specified are used where no other values are specified by the manufacturer or user. If other values are used, they will be stated. It is recognized that the manufacturer's specifications and instructions for installation and operation apply during all steps. The tests specified in this document are not necessarily sufficient for instruments specifically designed for unusually arduous conditions. Conversely, a reduced series of tests can serve adequately for instruments designed to perform within a more limited range of conditions. When a full evaluation, in accordance with this document, is not required or possible, only the tests which are required are performed and the results reported in accordance with the relevant parts of this document. In such cases, the test report will state that it does not cover the full number of tests specified herein. This second edition cancels and replaces the first edition published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) in 6.6.8 and Table 5, the magnetic field has been changed from 100 A/m to of 30 A/m (Mean Root Square); b) 6.10.4 and Figure 9 have been modified for better understandability; c) in 7.4, the reference to IEC 61187 has been deleted and replaced with a new Table 4: Document information.
