foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"
drafted.
This document replaces GB/T 17743-2017 "Limits and Measurement Methods for Radio Disturbance Characteristics of Electric Lighting and Similar Equipment".
Compared with GB/T 17743-2017, in addition to structural adjustment and editorial changes, the main technical changes are as follows.
--- The scope chapter deletes the restrictions on the use of power supply and battery operation for appliances (see Chapter 1, Chapter 1 of the.2017 edition);
--- Introduce three basic ports. shell port, local wired port and wired network port (see 3.4.6, 3.4.10, 3.4.14, Chapter 4,
Chapter 5, Appendix D);
--- In the frequency range of 300MHz~1GHz, introduce radiation disturbance limits (see Chapter 4, 4.4.2 of the.2017 edition);
--- Modified the expression of load terminal limit and CDNE (Alternative Method of Radiated Emission) limit (see Chapter 4, 4.3.2 of the.2017 edition);
--- Increase current probe measurement methods and limits for various ports (except for voltage limits and measurement methods) (see Chapter 4);
---For large EUT ( >1.6m), the magnetic field measurement method of 60cm loop antenna with a distance of 3m is added (CISPR14-1
method), as an alternative to 3m and 4m loop antenna systems (LLAS) (see 4.5.2);
--- Delete the insertion loss requirements and their related content in Appendix A (see 4.2, Chapter 5, Chapter 7,
Appendix A);
--- Introduce the term "module" (replacement of independent accessories) and the measurement requirements using the host (reference) system module (see 6.4);
--- Modified the specification of EUT stabilization time (see 7.8, 6.5.3 of the.2017 edition);
--- With appropriate reference to the CISPR16 series of standards, replace the appendix B (CDNE) with the CISPR16 series of related test methods.
Test methods (see 9.3.4.4, Appendix B of the.2017 edition);
--- Added a new method for measuring conducted disturbance of GU10 self-ballasted lamps (see A.1);
--- Modified the requirements for the metal hole of the tapered shell (see Figure A.2, Figure 7 of the.2017 edition).
This document is equivalent to CISPR15.2018 "Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment".
The following editorial changes have been made to this document.
--- Adjusted the list of normative reference documents according to the standard citations in the text.
