Quality Safety of Household Electrical Appliances –
Guidelines for Monitoring and Evaluation in the
Manufacturing Process
1 Scope
This Document provides guidance and suggestions for monitoring and evaluating the design,
raw materials and components, production, environmental facilities, personnel, etc. related to
product quality safety in the manufacturing process of household appliances. It proposes the
factors that need to be considered for the quality safety of the manufacturing process and the
factors, methods and processes of quality safety evaluation. At the same time, it provides
guidance and suggestions for the monitoring and evaluation of quality safety status in the
manufacturing process of food-contact household electrical appliances and customized
household electrical appliances.
This Document is applicable to the monitoring and evaluation of the quality safety status of the
manufacturing process by manufacturers of household appliances (including but not limited to
food-contact household electrical appliances and customized household electrical appliances),
and other similar enterprises may refer to this Document for implementation.

The provisions in following documents become the essential provisions of this Document
through reference in this Document. For the dated documents, only the versions with the dates
indicated are applicable to this Document; for the undated documents, only the latest version
(including all the amendments) is applicable to this Document.
GB 4706 (all parts) Safety of Household and Similar Electrical Appliance
GB 4806 (all parts) National Food Safety Standard
GB 4806.1-2016 National Food Safety Standard - General Safety Requirements on Food
Contact Materials and Articles
GB/T 14536 (all parts) Automatic Electrical Controls for Household and Similar Use
GB/T 26572 Requirements of Concentration Limits for Certain Restricted Substances in
Electrical and Electronic Products
GB/T 30976.1 Industrial Control System Security - Part 1: Assessment Specification
3.8 Traceability
The ability to understand the raw materials used in the product, the source of parts and
components, and the production status (including but not limited to processing, assembly, and
testing), etc. according to the marking, inspection and testing, and other information data of the
household appliances during the manufacturing process.
4 Guiding Principles
4.1 Design
In order to ensure the quality safety during the manufacturing process of household appliances,
the following principles should be followed in the design:
a) The design of household appliances shall fully consider the potential failure modes in the
manufacturing process in terms of mechanical danger, mechanical injury, stability,
durability, electric shock protection, electromagnetic compatibility, etc. Do well in
design prevention, ensuring the use safety of the household appliances, so that avoid the
hidden dangers of quality safety arising from the unscientific and unreasonable design of
the whole machine and parts.
b) In the links of material selection and process design, the adaptability in the manufacturing
process should be considered to avoid possible process defects and hidden dangers of
quality safety;
c) Design and plan the manufacturing process of household appliances; determine the
critical control points and operation and inspection instructions during the manufacturing
process, so that effectively control the quality safety risks of household appliances;
d) For the design-related technical information files (for example, manufacturing procedures,
design drawings, design input, design output, etc.) involved in the manufacturing process,
a process record file with traceability shall be formed.
4.2 Raw Materials and Components
In order to ensure the quality safety of household appliances during the manufacturing process,
the following principles should be followed in terms of raw materials and components:
a) It is crucial to evaluate the pre-tested raw materials and components in the
manufacturing process to confirm compliance with the durability requirements in GB/T
14536 (all parts) and GB 4706 (all parts). For components that are not tested individually,
and do not confirm whether complying with GB/T 14536 (all parts) and GB 4706 (all
parts), as well as that do not have markings, or do not use according to the marking, the
quality control should be carried out as the critical control points during the
manufacturing process.
b) For the raw materials and components that are used in the manufacturing process of
household appliances, confirm that they meet the requirements for the restricted use of
toxic and hazardous substances in GB/T 26572;
c) For the raw materials, components and parts that are used in household appliances and
affect the quality safety, traceability from procurement, processing, assembly to finished
product is required.
4.3 Manufacturing
In order to ensure the quality safety of household appliances during the production process, the
following principles should be followed in manufacturing:
a) In order to ensure that the quality safety status of household appliances in the
manufacturing process meets the requirements, it is very important to formulate the
procedural requirements, process specifications, operating procedures, process
requirements, control methods, etc. corresponding to the complete product
manufacturing process according to the corresponding standards and technical
agreements;
b) Identify and evaluate factors that may affect the quality safety of household appliances in
the manufacturing process; formulate control methods for the factors; eliminate and
reduce product quality safety risks caused by various factors; and carry out verification
that complies with provisions at critical control points that affect the quality safety of
household appliances;
c) Evaluate the personnel who directly affect the quality safety of household appliances in
the manufacturing process, including but not limited to production personnel; and
eliminate or reduce the quality safety risks caused by personnel factors, such a...
