The so-called heater refers to the equipment used for heating. At present, the most common heater in the market is the electric heater, which is a heating device that uses electricity as energy to heat and heat, and is widely used in various civil/public buildings such as houses, offices, hotels, shopping malls, hospitals, schools, train carriages and so on. However, in general, if such products want to be exported to the United States, they need to apply for UL certification.

The necessity of handling UL certification

1. The entire American market attaches great importance to product safety; Consumers and buyers will choose products with UL certification mark when purchasing products;

2. UL has a history of more than 100 years, and the image of safety is deeply rooted in consumers and the government. If you don't sell products directly to consumers, middlemen will also require products to have UL certification marks to make products sell well;

3. American consumers and buyers have more confidence in the products of enterprises;

4. There are more than 40,000 administrative regions in the United States, including the federal, state, county and municipal governments, all of which recognize the UL certification mark.

UL certification process of heater

1. Project determination: confirm the UL standard, certification cost and time, sample number, etc. on which the test is based;

2. Preparation of materials: According to the requirements of UL, the enterprise prepares various materials or documents required for certification;

3. Sample sending test: the enterprise sends the samples to the designated laboratory for product testing;

4. Issue report: The product test results meet the requirements of UL standard, and the test report is formally issued;

5. Factory audit: UL will conduct the first factory inspection of the production factory to ensure that it meets the standard requirements;

6. Logo use: After the examination meets the requirements, the applicant is officially authorized to use the UL logo.
