introduction
GB/T 46281, "Characteristics and Test Methods for Refrigeration Appliances for Household and Similar Purposes," aims to specify the characteristics and test methods for refrigeration appliances for household and similar purposes.
The sex and testing methods are proposed to consist of three parts.
---Part 1.General Requirements. The purpose is to define the scope, terminology and definitions, instruments, laboratories, and setup for refrigeration products.
---Part 2.Performance Requirements. This section aims to specify the general performance requirements and test methods for refrigeration appliances.
---Part 3.Energy Consumption and Volume. The purpose is to specify the measurement of energy consumption and volume.
Characteristics and test methods of household and similar refrigeration appliances
Part 2.Performance Requirements
1.Scope
This document specifies the basic requirements for household and similar refrigeration appliances that use natural or forced air convection for internal cooling.
Features describe the performance testing methods.
Although this document describes some commonalities in the settings of different tests (therefore, it may be advantageous to perform all tests on the same sample).
(These are individual tests used to evaluate the specified characteristics of the tested sample. This document does not specify the generalization of sample test results into...)
A procedure for predicting the overall characteristics of a selected sample.

4 Performance Requirements and Test Items
4.1 General Requirements
This document specifies the tests required to evaluate the performance of refrigeration appliances for household and similar purposes. While these tests are not mandatory under this document.
However, when conducting tests, they should be carried out in accordance with the provisions of this document.
4.2 Storage Temperature Test
Storage temperature testing is used to determine whether refrigeration appliances can meet the storage requirements of each compartment under the ambient temperature required for the rated climate type.
Storage temperature requirements. See Chapter 6.
4.3 Cooling Capacity Test
Cooling capacity testing measures the load on a cold storage compartment by determining the time it takes to cool a specified test load from ambient temperature to a specified temperature.
Processing capacity. See Chapter 7.
