Introduction

At present, my country's household cooking appliances industry is developing rapidly, and the technical level of the industry is constantly improving. With the improvement of our people’s living standards, And consumers' pursuit of high-quality life, also put forward higher requirements for product performance. However, at present, my country has not targeted such products. Products, systematically formulate relevant performance test methods and standards, and there is no uniform performance test method in the industry, resulting in uneven product quality Uneven, vicious competition in the market. In order to guide the sustainable and healthy development of the industry, improve the performance level of products and meet the needs of consumers, GB/T 38051 was formulated "Household Cooking Appliances" standard. On the road to industry and product standardization, this standard has played a fundamental role. In order to ensure compliance with international standards In keeping with synchronization, this standard is formulated in a form equivalent to adopting the latest international version of the IEC standard. This standard covers the main home appliances in the cooking appliance industry, namely electric stoves, ovens, steamers, grills and stoves, including consumers The main performance characteristics of interest and the interests of consumers are specified and the measurement methods for these characteristics are specified. Due to the length of the document and the product There are technical differences between GB/T 38051 "Household Cooking Appliances" to be composed of two parts. ---Part 1.Test methods for the performance of electric stoves, ovens, steamers and grills. Its purpose is to have similar structure and use Determination of performance test methods for four types of products such as electric stove, oven, steamer and grill. ---Part 2.The performance test method of the stove. Its purpose is to determine the performance test for cooktop products with unique cooking characteristics. Try the method. Household cooking appliances part 1.electric stove, Oven, steamer and grill performance test method

1 Scope

This document specifies the performance test methods for household electric stoves, ovens, steamers and grills. The oven referred to in this document may or may not have a microwave function. The manufacturer should specify the main cooking function of the appliance-microwave function or heating. The main cooking functions should be carried out according to the existing methods. Energy consumption measurement. If the main cooking function is declared as the microwave function in the instructions for use, IEC 60705 is used for energy consumption measurement. If sound If the main cooking function is heating, this document is used for energy consumption measurement. If the manufacturer does not declare the main function, the microwave function and heating performance should be measured as much as possible. Note 1.For load heating energy consumption and time measurement (see 7.4), it does not apply to. ---Microwave combination function; ---Oven with reciprocating tray or turntable; ---Small cavity oven; ---Oven without adjustable temperature control; --- Heating functions other than those defined in 3.12~3.14; ---Apparatus with a single steam function (3.15). Note 2.This document does not apply to. ---Microwave oven (IEC 60705); ---Portable appliances for cooking, roasting, steaming and similar purposes (IEC 61817). This document specifies the main performance characteristics of interest to users of these appliances, and specifies the measurement methods for these characteristics. This document does not specify the classification or ranking of performance. Note 3.Some of the tests specified in this document are not considered to be repeatable, because the results obtained by different laboratories may be different. Therefore, these trials The test is only used as a comparative test. Note 4.This document does not involve safety requirements (IEC 60335-2-6 and IEC 60335-2-9). Note 5.The appliances described in this document can be embedded or placed on a work surface or on the ground. Note 6.Regarding the grill and steam functions, there is no energy consumption measurement method available.
