Guidelines for the verification of equipment for electromagnetic compatibility testing

1 Scope

GB/Z 41634-2022 is the Chinese national standard on guidance for intermediate checks of electromagnetic compatibility testing equipment, in the field of telecommunications and audio-video engineering. The /Z suffix marks it as a guiding technical document: it does not prescribe requirements that can be certified against, but sets out the technique, the method or the state of the art that the standards bodies recommend following. It was issued on 11 July 2022 by the State Administration for Market Regulation; Standardization Administration of China. As a guiding technical document it carries no separate date of entry into force: it applies from publication. Classification: ICS 33.100, CCS L06. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document gives the verification and confirmation of the main metrological characteristics or functions of the testing equipment, facilities and systems during the adoption of electromagnetic compatibility testing laboratories. guide. This document applies to the period carried out by the electromagnetic compatibility testing laboratory to maintain the credibility of the calibration status of testing equipment, facilities and systems check.

3 Terms and Definitions

The terms and definitions defined in GB/T 4365-2003 and the following apply to this document.

3.1 calibration A set of operations under specified conditions, the first step of which is to determine the relationship between the magnitude provided by the measuring standard and the corresponding indication, the second step It is to use this information to determine the relationship between the measurement results obtained from the indication value, where both the quantity provided by the measurement standard and the corresponding indication value have measurement uncertainty. fixed. [Source: JJF1001-2011, 4.10]

3.2 verification checks To verify whether the main metrological characteristics or functions of testing equipment, facilities and systems can meet the method requirements or specified requirements in accordance with the specified procedures operation.

Note 1."Method requirements" refers to the requirements for equipment (function or metrological characteristics) for the method of an electromagnetic compatibility testing laboratory to carry out a testing item. Note

2.The "specified requirements" are determined by the electromagnetic compatibility testing laboratory according to the use requirements and risks, and are usually stricter than the "method requirements".

3.3 check device Devices, equipment or samples used to routinely verify the performance of testing equipment, facilities, and systems. [Source: JJF1001-2011, 8.10, with modifications]

3.4 intermediatechecks Testing equipment, facilities, and systems between adjacent calibrations or during use, verify their main metrological characteristics or The operation performed by whether the function can continue to meet the requirements of the method or the requirements of the regulations.
