What is the GB 4706 Testing Report for Household Appliances?

In daily life, household appliances are closely connected to our routines. But are you aware that behind these commonly used appliances, there is a strict set of safety standards safeguarding our well-being? Today, let's take a closer look at the GB 4706 standard.

What is the GB 4706 Standard?

GB 4706 is a national standard in China for the safety requirements of household and similar electrical appliances. It applies to various types of household appliances and exists to ensure the safety of consumers' personal and property protection while using these appliances.

Process for Obtaining the GB 4706 Testing Report:

1. Business Consultation: The applicant must provide product information, images, and testing requirements.

2. Engineering Quotation: Engineers provide a verbal quotation based on the information provided by the applicant.

3. Provide Information: After accepting the verbal quotation, the applicant must submit test samples to the designated agency.

4. Payment: After receiving the samples, the agency issues a written quotation, and the applicant arranges payment accordingly.

5. Sample Testing: Products are tested according to applicable standards.

6. Issuance of Report: Once testing is complete, the laboratory issues a third-party CNAS/CMA testing report, and the process is concluded.

Testing Items for the GB 4706 Household Appliance Report:

1. Labels and Instructions; Protection against access to live parts.

2. Starting of electric appliances; Input power and current.

3. Heating; Leakage current and electric strength under operating temperature.

4. Moisture resistance; Leakage current and electric strength.

5. Overload protection for transformers and related circuits; Abnormal operation.

6. Mechanical strength; Structure; Internal wiring; Power connections and external flexible cables.

7. Terminals for external conductors; Grounding measures; Screws and connections.

8. Electrical clearance, creepage distances, and solid insulation; Heat resistance and flammability; Corrosion resistance.

Documents Required for the GB 4706 Testing Report:

1. Circuit schematic diagram.

2. Printed circuit board layout and component placement diagram.

3. English manual (must include manufacturer name or trademark, model, parameters, installation instructions, and necessary safety warnings).

4. Model variation description (for multiple models in the same series, differences and similarities should be clearly listed and stamped).

5. Labels/Nameplates.

6. Product installation structure diagram/Exploded view (indicating component numbers and names).

7. List of key components (must be stamped).

8. Copy of certificates for safety-related key components (based on the "key component list," to verify whether the number, parameters, and actual sample match).

The Significance of the GB 4706 Standard:

The implementation of the GB 4706 standard is crucial for ensuring the safety of household appliances and similar electrical products. It provides manufacturers with a unified standard and guidelines to ensure that products meet safety requirements during design, manufacturing, and use, thus preventing accidents and damages. Furthermore, the GB 4706 standard also serves as a basis for regulatory authorities to assess and supervise the safety of household appliances and similar electrical appliances sold in the market, providing critical protection for consumer safety.
