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 of household and similar refrigeration appliances and Test Methodology Part 3: Power Consumption and Volume

1 Scope

This document specifies the basic requirements for household and similar refrigeration appliances that use natural or forced air convection for internal cooling.

The characteristics are described, along with the testing methods for checking these characteristics.

This document specifies methods for determining power consumption characteristics and describes how to combine these methods to evaluate different usage and climatic conditions.

The document also describes the power consumption. The determination of the volume is also described.
