UL508 Industrial Control Equipment Standard

UL508 is the detection of industrial control products testing standards (such as: relays, contactors, control switches, reactors, aluminum case resistors, industrial switching power supply, pressure switches, etc.), which is exported to North America to obtain UL certification testing basis.

Resistor UL508 certification requires information

1. BOM;

2. Plastic material yellow card;

3. Electrical parameters;

4. Contact material dimension drawing;

5. Circuit diagram;

6. Product identification.

Resistor UL508 certification testing items

1. Temperature rise test;

2. Overload test;

3. Life test;

4. Molding test;

5. Steel ball impact test;

6. Withstand voltage test.

Resistor UL508 certification cycle:

2-3 months.

Resistor UL508 certification process:

1, project determination: confirm the test based on UL standards, certification costs and time, sample quantity, etc.;

2, data preparation: according to UL's requirements, enterprises ready for certification of the information or documents;

3, sample testing: enterprises will send samples to Ancojet testing and certification laboratory for product testing;

4, the issuance of the report: product test results in line with UL standard requirements, the official issuance of the test report;

5, factory audit: UL will be the production plant for the first factory inspection to ensure compliance with the standard requirements;

6, logo use: audit meets the requirements, the applicant formally authorized to use the UL mark.
