GB/T 17743-2017 standard updates

2.1, GBT17743-2017 updates and differences between the old and new versions

2.1.1 Expanded coverage not covered by the standard.

Appliances explicitly specified within other CISPR standards are out of scope, even if they have a built-in lighting function.

Examples of what GB17743-2017 does not cover are:

  • -Built-in illuminator for display backlighting and signaling
  • -Hood, refrigerator, freezer;
  • -Copiers, slide projectors;
  • -Lighting equipment for road motor vehicles.

Examples of what GB17743-2007 does not cover are.

2.1.2, GBT17743-2017 section 4.4.2 increased the 3m test distance limit, continue to retain the CDN alternative test method

GBT17743-2017 Section 4.4.2 adds a 3m test distance limit

GBT17743-2017 Section 4.4.2 adds a 3m test distance limit

2.1.3, GBT17743-2017 added "support plate for light rope";

We offer support flat products for light ropes in accordance with GBT17743-2017, if you need, please click to contact us for quotation information.

Lamp cords were the control pull cords for early light switches, and nowadays pull cord switches have almost always been replaced by modern switches

2.1.4, GBT17743-2017 added Appendix D gives the applicable test methods and limit values for different types of lamps.

  • GBT17743-2017 added Appendix D-Test methods and limits for self-ballasted lamps and ELV lamps
  • GBT17743-2017 added Appendix D-Test methods and limits for LED light sources, incandescent lamps and all other types of lamps
  • GBT17743-2017 added Appendix D-Test Methods and Limits for Incandescent Lamps and Fluorescent Lamps of Starter-Switched Operating Type
  • GBT17743-2017 added Appendix D-Self-Capacitating Emergency Illuminators and LED Light Sources, Test Methods and Limits for Transportation Lighting
  • GBT17743-2017 adds test methods and limits for light cords and all other types of lamps and lanterns
  • GBT17743-2017 added Appendix D-Dimming devices, transformers, converters, test methods and limits for semi-luminaires
  • GBT17743-2017 added Appendix D - Test methods and limits for double-ended lamp adapters and semi-luminaires with separate starters and triggers

Updates to the CISPR15-2018 standard

3.1, Name:

3.1.1, CISPR15-2018-ED9.0 Limits and methods of measurement of radio disturbance characteristics of electrical lighting and similar equipment

Posted on May 15, 2018

3.2, CISPR15-2018 update

CISPR 15:2018 Application to emissions (radiated and conducted) of radiofrequency interference: lighting equipment (3.3.16).

  • -Lighting part of multifunctional equipment, where the lighting part is the main function.
  • UV and infrared radiation equipment for residential and non-industrial applications.
  • -Advertising signboards.
  • -Decorative lighting.
  • -Emergency.
  • Excluded from the scope of this document:- Components or modules used in lighting fixtures that are not replaceable.
    • -Lighting equipment operating in the ISM band (according to the provisions of ITU Radio Regulation 63 (1979)).
    • -Lighting equipment for aircraft and airport facilities (runways, services, platforms).
    • -video signals.
    • mounting
    • -Electromagnetic compatibility requirements in the radio frequency range are specified in other CISPR standards for devices, even if they contain built-in lighting functions.
    • The frequency range covered is 9 kHz to 400 GHz. there is no need to perform measurements at any of the restricted frequencies specified in this document.
    • Multi-functional devices that are also applicable to different clauses and/or other standards of this document need to comply with the provisions of the respective clauses/standards and have the relevant functions.
    • For equipment outside the scope of this document, which includes lighting as an auxiliary function, there is no need to evaluate the lighting function of this document separately, provided that the lighting function is performed during the evaluation. Compliance with applicable standards. The radiated emission requirements in this document shall not apply to intentional transmissions from radio transmitters as defined by the ITU, nor to any spurious emissions associated with such intentional transmissions.

For the remainder of this document, electronic lighting and similar equipment as defined herein falls within the scope of this document, regardless of whether the term "lighting equipment" or "EUT" is used. This Ninth Edition cancels and replaces the Eighth Edition published in 2013 and its Amendment 1:2015.This edition constitutes a technical revision.
