UL507 is the UL standard for floor fans, table fans, ceiling fans, attic fans, exhaust fans, duct fans, industrial fans, low-pressure fans, range hoods and other electric fan products.
What is UL507?
UL 507 is a North American safety standard for ventilation equipment such as electric fans. It is developed by the American Safety Laboratory (Underwriters Laboratories, referred to as UL), which aims to ensure that the safety, reliability and performance of electric fans meet relevant requirements.
UL 507 standards specify the material, manufacturing and design requirements of electric fans, as well as safety and performance test methods. For example, the standard requires electric fans to meet the requirements of electrical safety, mechanical safety and thermal safety, as well as performance indicators such as air volume, noise and vibration.
By obtaining the UL 507 certification, electric fan manufacturers can prove that their products meet the requirements of the standard, improve the market competitiveness of their products, and allow consumers to use their products with more confidence. At the same time, the certification also helps to protect the safety of consumers' lives and property and avoid potential safety hazards caused by substandard products.
UL507 Certification Test Project
the UL507 certification test program usually includes the following:
1. Electrical safety testing: including electrical insulation, grounding resistance, leakage current, arc resistance and voltage resistance tests.
2. Mechanical safety testing: including the protection of rotating parts, the mechanical strength and impact resistance of the casing.
3. Thermal safety test: including temperature rise test and overheat protection test of electric fan.
4. Performance test: including air volume, noise, vibration, power efficiency and other tests.
Specific test items may vary depending on the product, UL certification bodies will develop appropriate test plans and test standards based on the characteristics of the product.
UL507 certification process
1. Project determination: confirm the style, model number of the application;
2. Data preparation: Provide product information that needs to be applied, including product model list, product drawings, product photos, product materials, etc;
3. Sample delivery test: give the corresponding test certification scheme according to the application product information, confirm the test items, and send the samples to the Ancorset testing certification laboratory;
4. Issued report: the product test results meet the requirements of UL standard, and the test report is officially issued;
5. Factory audit: UL will conduct the first factory inspection of the production plant to ensure compliance with standard requirements;
6. Mark use: After the audit meets the requirements, the applicant is officially authorized to use the UL mark, obtain the certificate, and the project is completed.
