What is the ETL Mark? Its Importance in the Electrical Industry

The ETL Mark: A Crucial Step for Electrical Products Entering the Market

Have you ever noticed a small black mark with the words “ETL Listed” on electrical products like lamps, appliances, or cables? That’s the ETL mark – a vital certification indicating that the product has met stringent safety and quality standards.

What is ETL?

ETL stands for Electrical Testing Laboratories, ETL is owned by Intertek. The ETL seal is issued after the product has undergone rigorous testing for factors such as:

  • Electrical Safety: Ensuring the product poses no danger to users or the environment.
  • Performance: Verifying that the product functions as the manufacturer claims.
  • Standards Compliance: Confirming that the product meets national and international safety standards.

The Process of Obtaining the ETL Mark

To obtain the ETL mark, manufacturers must go through a rigorous process:

  1. Application: The manufacturer applies for ETL certification through Intertek.
  2. Initial Factory Audit (IFA): Intertek experts visit the factory to inspect production processes, quality control, and documentation.
  3. Product Testing: Product samples are sent to ETL’s laboratory for detailed testing.
  4. Follow-Up Audits (FUA): After certification, the factory undergoes periodic audits to ensure continued quality. VIS – Intertek’s representative in Vietnam will periodically inspect factories on a quarterly basis.
