3 Terms and Definitions

The terms and definitions which are established in GB/T 21001.1-2007 and

GB/T 21001.2-2007 AND listed below apply to this Part.

3.1

Energy consumption coefficient of remote refrigerated display cabinets

GB/T 26920.1-2011 unit of kilo-watthour per 24 hour square meter [kWh/(24h·m

)].

When the measured energy consumption coefficient value is less than or equal to the evaluating value of energy conservation ECC evaluating value of energy conservation , it is judged that the energy consumption of this batch of products complies with the technical requirements of energy conservative product certification.

6 Test method and report format

It shall conduct test in accordance with GB/T 21001.1-2007, GB/T 21001.2-

2007 and relevant requirements of Chapter 4. The ECC test report format is shown in Appendix B. The test for each equipment shall be with independent test report.

7 Inspection rules

TAKE one sample from a batch of products to test its energy consumption coefficient; if it fails to meet the specified requirements, TAKE two samples again AND the measured values shall meet the requirements, otherwise this batch of products is judged as unqualified.

For a single product, TEST its energy consumption coefficient; if it fails to meet the requirements, it is judged as unqualified.

8 Energy efficiency grade mark

8.1 The manufacturer shall, in accordance with the requirements of this Part,

TEST the energy consumption coefficient of its products.

8.2 The manufacturer shall, in accordance with the test results, determine the product's rated energy efficiency grade.
