On December 29, 2022, the Standardization Administration of China (SAC) released a batch of mandatory national standards on energy efficiency. This article summarizes the changes in the two newly-revised mandatory standards for lamps and ballasts.
GB 17896-2022 Minimum allowable values of energy efficiency and energy efficiency grades of ballasts for gas discharge lamps for general lighting
The standard stipulates the energy efficiency grade, minimum allowable values of energy efficiency and testing methods for ballast that are used on certain types of tubular fluorescent lamps, single-capped electrodeless fluorescent lamps, metal halide lamps and high-pressure sodium vapour lamps (further product scope are specified in the standard with technical parameters).
The main modification of the standard include:
· Deleted the energy-saving assessment value for ballasts, together with the ballast efficiency factor (BEF), energy-saving assessment value and minimum allowable target value for ballasts on high-pressure sodium vapour lamps.
· Changed the definition of standby power.
· Deleted general requirements.
· Deleted the requirements on system input power for the ballast of tubular fluorescent lamps when it’s at 25% light output.
· Deleted the technical requirements for energy-saving assessment.
· Deleted the required efficiency value for ballast of high-pressure sodium vapour lamps.
· Deleted the classification requirements for standby power of ballast used on single-capped electrodeless fluorescent lamps.
· Following contents are deleted:
- Efficiency examination method in the manufacturing process of ballasts used for tubular fluorescent lamp.
- Sampling inspection method for energy efficiency of AC supplied electronic ballasts used for single-capped electrodeless fluorescent lamps.
- Examination rules of ballast used for metal halide lamps and high-pressure sodium vapour lamps.
· Changed the testing methods.
This standard is China national specific standard without any connection of IEC standard.
GB 19044-2022 Minimum allowable values of energy efficiency and energy efficiency grades of fluorescent lamps for general lighting
The revised standard stipulates the energy efficiency grade, minimum allowable values of energy efficiency and testing methods for following types of florescent lamps that :
· Rated voltage 220V, frequency 50Hz with AC power supply, screw caps or bayonet caps, and integrate components for starting controlgear and igniting point stabilization, self-ballasted fluorescent lamps with rated power at 3W~60W and self-ballasted electrodeless fluorescent lamps with rated power at 10W~60W.
· work on the AC power frequency with starter, and can work on the high frequency line; along with preheating cathode lamps that works on high frequency line (hereinafter referred to as “double-capped fluorescent lamp”).
· Single-capped fluorescent lamps with preheating cathode.
· Single-capped electrodeless fluorescent lamps with rated power 30W~400W
The standard does not apply for self-ballasted fluorescent lamp with hood.
The main technical modification of the 2022 version include:
· Added the terms and definition of luminous efficacy and the minimum allowable values of energy efficiency for fluorescent lamps.
· Deleted a serial of terms and definitions for the initial luminous efficacy, minimum allowable value of energy efficiency, and energy saving assessment value for five types of products (self-ballasted fluorescent lamps, double-capped fluorescent lamp, single-capped fluorescent lamp, self-ballasted electrodeless fluorescent lamps and single-capped electrodeless fluorescent lamps)
· Deleted general requirements.
· Deleted calculation of luminous efficacy for self-ballasted fluorescent lamps.
· Deleted the stipulation on determining the luminous efficacy of unlisted rated power for self-ballasted electrodeless fluorescent lamp products through linear interpolation.
· Deleted the technical requirements for energy-saving assessment of self-ballasted fluorescent lamps, double-capped fluorescent lamp, single-capped fluorescent lamp, self-ballasted electrodeless fluorescent lamps and single-capped electrodeless fluorescent lamps.
· Added technical requirements of color render index for fluorescent lamps that use tri-phosphor fluorescent powder.
This standard is China national specific standard without any connection of IEC standard.
Foreign manufacturers are advised to verify whether the applying scope change would affect current products, as well as if any possible impacts would be caused by the revised requirements.
As these 2 standards are different from IEC standards, the overseas manufacturers should read these standards carefully to check if your products comply with them.
