2.3 See Annex 1 for an example of the label style, which can be found on the "China Energy Efficiency Labeling Network"
3 Energy efficiency testing
3.1 The detection of energy efficiency performance related parameters such as no-load loss and load loss should be based on
-3-
The currently valid version of GB.20052.
3.2 The format of the "Power Transformer Energy Efficiency Test Report" (hereinafter referred to as the test report)
Load.
3.3 Producers or importers can use their own testing laboratories, or entrust them to obtain
Qualified third-party inspection and testing institutions conduct product inspections, and based on energy efficiency
Rate compulsory national standards and determine product energy efficiency ratings.
Producers or importers who use their own testing laboratories to determine energy efficiency levels shall ensure that
Certify that its testing laboratory is capable of testing in accordance with mandatory national standards for energy efficiency
And encourage them to obtain accreditation from national accreditation bodies.
3.4 If you use your own testing laboratory for testing, you should provide a laboratory testing ability certificate
Clear materials (including laboratory personnel capabilities, equipment capabilities and testing management practices), have been
If it has been approved by a national accreditation body, a copy of the corresponding accreditation certificate shall also be provided;
If a third-party inspection and testing agency conducts testing, it shall provide the qualification certification of the inspection and testing agency.
A copy of the certificate.
Authorized agencies should review the energy efficiency labels and product energy efficiency used by producers and importers.
The test report is verified.
4 Determination of identification information
4.1 The producer refers to the owner or user of the product brand who is legally responsible for the quality of the product
