Updates to two automotive lighting GB standards13. June 2019
Recently, two GB standards regarding automotive lighting systems have been updated. The old standard GB 5920-2008 will be replaced by GB 5920-2019 (“Photometric characteristics of front and rear position lamps, end-outline marker lamps and stop lamps for motor vehicles and their trailers”) and GB 23255-2009 will be superseded by GB 23255-2019 (“Photometric characteristics of daytime running lamps for power driven vehicles”).
Significant changes in GB 5920-2019 to the previous standard include a modified definition for “single lamp”, the introduction of the concept of “interdependent lamp” and LED as a light source. Additionally, the testing requirements for the emitted color of the light have been modified, as well as the technical requirements for the variable intensity control of the rear position lamps, the end-outline marker lamps and the stop lamps. Generally, this standard has been modified in relation to ECE R7 Rev. 6.
Additions to GB 23255-2019 include new requirements for interdependent lamps and the light distribution angle range. Modifications have been made to the requirements for maximum luminous intensity and the area of the apparent surface. Furthermore, the photometric requirements below the H-H-line have been changed. Revisions to this standard have been made with reference to ECE R87 Rev 3.
Both standards will be implemented by January 1st, 2020, by which date the relevant certification bodies and test laboratories will be in compliance and will have implemented them accordingly.
Products that were certified according to the old versions need to be updated. This can be done by submitting a change application. If the product, in the meantime, has to undergo tests it will be updated automatically. If you are unsure, please contact us.
