Title: What is UL 479 and How Does it Safeguard Your Electrical Equipment?

When it comes to the safety and reliability of electrical and electronic equipment, compliance with UL 479 is essential. This technical standard, also known as "Standard for Safety of Household and Commercial Electric Appliances," is developed and maintained by Underwriters Laboratories (UL), a globally recognized independent safety science company. UL 479 primarily focuses on the safe operation and performance of electrical appliances in both residential and commercial settings. In this article, we will explore the purpose of UL 479, its key requirements, and how it helps safeguard your electrical equipment.

What is UL 479?

UL 479 is a technical standard that relates to electrical and electronic equipment. It sets out the requirements for safety, performance, and reliability of these types of equipment. The standard covers various aspects such as construction, temperature ratings, current-carrying capacities, and durability. The main purpose of UL 479 is to ensure that electrical and electronic equipment meet specific safety requirements, which helps prevent hazards like electric shock, fire, or other potential risks associated with faulty equipment.

Key Requirements of UL 479

Compliance with UL 479 is essential for ensuring the safety and reliability of electrical and electronic equipment. Key requirements of UL 479 include:

Safety: The equipment must meet essential safety requirements, which are outlined in UL 474, or "Standard for Safety of Household and Commercial Electric Appliances."

Performance: The equipment must perform as intended, with minimal deviations from the specified requirements.

Reliability: The equipment must remain reliable and in good working order, with minimal maintenance required.

UL 474: Understanding the Basics

UL 474, also known as "Standard for Safety of Household and Commercial Electric Appliances," is a set of guidelines developed and maintained by Underwriters Laboratories (UL). The standard primarily focuses on the safe operation and performance of electrical appliances in both residential and commercial settings. It establishes specific requirements for design, construction, testing, and certification of these appliances to ensure they meet strict safety standards.

Key Features of UL 474

UL 474 covers a wide range of products, including but not limited to kitchen appliances, cleaning equipment, heating and cooling devices, and consumer electronics. It establishes requirements for the design, construction, testing, and certification of these appliances to ensure they meet strict safety standards.

Conclusion

UL 479 and UL 474 are both important technical standards that help ensure the safety and reliability of electrical and electronic equipment. Compliance with these standards is essential for protecting consumers from potential hazards associated with faulty equipment. By understanding the requirements outlined in UL 479 and UL 474, manufacturers can design and produce products that are safe, efficient, and reliable.
