1 Scope

This part of GB/T (Z) 6113 is intended to provide information to the developers and revisioners of the CISPR Electromagnetic Compatibility (EMC) standards.

A guide to the uncertainty. In addition, useful background information is provided for those who actually apply the uncertainty content in this section.

This section is limited to all uncertainties associated with compliance testing of EMC standards.

The purpose of this section.

a) Identify the impact uncertainty associated with the statement that "a given product meets the requirements of the CISPR standard" (standard compliance does not

The parameter or source of the degree of certainty (abbreviated SCU, see 3.1.16);

b) give an assessment guide on the magnitude of the uncertainty of the criteria compliance;

c) Give guidance on applying the criteria compliance uncertainty to the CISPR standardized conformance test.

Therefore, this section can be used as a manual to help standard writers consider how to deal with current or future uncertainties.

The "CISPR Standards" developed are supplemented, quoted or coordinated as necessary. This section also judges regulatory agencies, accreditation bodies and test engineers.

Provide guidance on the quality of work performed by EMC testing laboratories that are CISPR standardized compliance tests. When using different replacement test parties

The uncertainty given in this section can also be used as a guide when comparing the test results obtained by the method (and its uncertainty).

The uncertainty of the compliance test is also related to the probability of electromagnetic interference (EMI) problems occurring in practice. This section recognizes this view

And gave a brief introduction. However, this section is not considered.
