Scope
This standard specifies the energy efficiency level, limited energy efficiency values, energy-saving evaluation values, and test methods of double ended fluorescent lamps (hereinafter referred to as double ended fluorescent lamps) for general lighting. This standard applies to the following two types of lamps: preheating cathode lamps that work on AC power supply circuits with starters and can work on high-frequency circuits, and preheating cathode lamps that work on high-frequency circuits The following documents are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document GB/T10682 Performance Requirements for Double ended Fluorescent Lamps
GB 18774 Safety Requirements for Double ended Fluorescent Lamps
Terms and Definitions
The following terms and definitions defined in GB/T 10682 apply to this document
Initial luminous efficiency for double capped fluorescent lamps
The ratio of the measured initial luminous flux to power of a double capped fluorescent lamp under standard test conditions, in lumens per watt (1lm/W).
Minimum allowable values of energy efficiency for double capped fluorescent lampsFunction of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problemsBaijian and testing process:
1. Telephone communication and confirmation of requirements
2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:
