Introduction

To standardize electromagnetic compatibility (EMC) measurements, consider measurement uncertainties, provide relevant background information, and classify EMC products... The formulation and revision of standards laid the technical foundation. GB/T (Z)6113 "Specification for Measurement Equipment and Methods for Radio Interference and Immunity" stipulates the requirements for radio interference and immunity measurement.

The model for measuring electrical disturbance and immunity, including measurement equipment, methods, technical requirements for measurement uncertainty, and calculation limits, consists of four parts, the first of which is... Part 1 is the specification for radio interference and immunity measurement equipment; Part 2 is the specification for radio interference and immunity measurement methods; Part 3 is... Technical report on radio interference and immunity measurement; Part 4 covers uncertainty, statistics, and limit modeling. Part 4 is proposed to be divided into 5 parts.

---Part 4-1.Uncertainty, Statistics, and Limit Modeling Uncertainty in standardized EMC tests. The purpose is to provide electromagnetic... The developers and revisers of compatible standards provide guidance on handling uncertainty.

---Part 4-2.Uncertainty, Statistics, and Limit Modeling. Uncertainty of measurement equipment and facilities. The purpose is to specify the basis... How is the measurement uncertainty (MIU) applied when determining compliance with CISPR disturbance limits for equipment under test? The method.

---Part 4-3.Uncertainty, Statistics, and Limit Modeling - Statistical Considerations for Determining EMC Compliance of Batch Products. Objective It describes the statistical considerations for determining the electromagnetic compatibility (EMC) compliance of batch products.

---Part 4-4.Uncertainty, Statistics and Limit Modeling. Statistics of Complaints and Limit Calculation Models for Radio Services.

The purpose is to provide suggestions on how to handle radio interference complaint statistics and to provide measurement methods for interference field strength and interference voltage at test sites. Calculation of limits for measurement.

---Parts 4-5.Uncertainty, Statistics, and Limit Modeling - Conditions for Using Replacement Experimental Methods. The aim is to provide product committees with... When using alternative test methods, it provides conversion methods between the established test method limits and the specified test method limits.

1 Scope

This document specifies the conversion method between two limits for the Product Committee, namely, the "determined limit" in the "determined test method".

Convert to "Derived Limits" in "Alternative Test Methods". This method is generally applicable to all types of disturbance measurements, but focuses more on radiated disturbances.

Disturbance measurements (i.e., field strength and total radiated power) are used because several alternative test methods for field strength measurements have been established. The Product Committee and responsible... When other organizations that set emission limits decide to use alternative test methods and corresponding limits in product standards, this method can be used to achieve the limits. The conversion.
