Standards & Compliance

The testing was conducted in accordance with GB4706.1-2005: “Safety of Household and Similar Electrical Appliances – Part 1: General Requirements”.

This is the foundational Chinese national safety standard for household electrical appliances, harmonized with the international IEC 60335 series. The standard covers essential safety aspects including:

Clause 7: Marking and instructions – verification of proper labeling, rating plates, and user instructions
Clause 10: Input power and current – measurement of actual power consumption versus rated values
Clause 13: Leakage current and electric strength at operating temperature – safety under normal use conditions
Clause 16: Leakage current and electric strength – dielectric withstand and insulation resistance testing
Clause 20: Stability and mechanical hazards – tip-over and physical safety tests
Clause 21: Mechanical strength – impact resistance and durability assessment
Clause 22: Construction – verification of safe design, spacing, materials, and assembly

The S3 tire inflator successfully passed all seven test categories specified in the commissioned testing scope.

Frequently Asked Questions

What does GB4706.1-2005 compliance mean for the ETENWOLF S3?

GB4706.1-2005 is China’s mandatory national safety standard for household electrical appliances. Compliance means the S3 inflator has been tested and verified to meet essential safety requirements including proper electrical insulation, protection against electric shock, mechanical safety, thermal safety, and correct product marking. This certification is required for legal sale in the Chinese market.

Why is the S3 classified as a Class III appliance?

Class III appliances operate at safety extra-low voltage (SELV), typically below 50V AC or 120V DC. The S3 operates at 5V DC via USB Type-C, making it inherently safer than mains-voltage products. Class III devices rely on their low voltage as the primary protection against electric shock, rather than insulation or grounding systems required by Class I or II appliances.

What testing scope was covered in this report?

This report covers seven specific test categories from GB4706.1-2005: marking and instructions, input power and current measurement, leakage current and dielectric strength (both at operating temperature and standard conditions), stability and mechanical hazards, mechanical strength, and construction requirements. These represent core safety aspects but may not constitute a complete certification test report which could include additional clauses.

Can this report be used for export or international markets?

This GB4706.1-2005 report is primarily recognized for the Chinese domestic market. For international markets, separate certifications may be required such as CE marking for Europe, FCC for the United States, or other region-specific safety certifications. However, since GB4706 is harmonized with IEC 60335, this test data may support applications for other certifications.
