UL 60335-2-40 is the Future of HVACR Electrical Safety Compliance. Intertek can guide you through everything you need to know

What is UL 60335-2-40?

UL 60335-2-40 is a safety standard for household and similar electrical appliances. UL 60335-2-40 outlines various safety requirements, including protections against electric shock, fire hazards, and mechanical hazards. It also covers requirements for marking and instructions for use, and testing procedures to ensure compliance with the safety requirements.

UL 60335-2-40 is one of several safety standards that manufacturers of electrical appliances must comply with in order to ensure the safety of their products for consumers. Compliance with these standards is typically indicated by a certification mark on the product, such as the ETL mark.

Benefits of UL 60335-2-40 Testing

The benefits of UL 60335-2-40 testing are numerous and include the following:

  1. The primary benefit of UL 60335-2-40 testing is to ensure that HVACR equipment meet minimum safety standards. This helps prevent potential hazards such as electric shock, fire, and mechanical injuries to users and anyone in the vicinity of the appliance.
  2. Testing your products to UL 60335-2-40 standards ensures compliance with safety regulations and standards. This helps to avoid legal problems and penalties, and helps protect your brand's reputation.
  3. UL 60335-2-40 testing is also an effective way to ensure that your products meet quality standards. Meeting these standards can help improve your product's reliability, reduce returns, and improve customer satisfaction.
  4. UL 60335-2-40 testing can help you gain access to international markets. Many countries require that products meet recognized standards before they can be sold in their markets.
  5. Meeting UL 60335-2-40 standards can also give you a competitive advantage. Consumers are increasingly concerned about the safety of the products they use, and having a safety mark on your products can help build trust and confidence in your brand.
