Title: What is UL 62368-1 2019 and UL 1699:2020? A Comprehensive Guide

The safety of electrical products is of utmost importance in today's world. With the rapid development of new technologies, traditional safety standards were no longer sufficient to ensure the safety of modern electronic products. This has led to the development of UL 62368-1:2019 and UL 1699:2020, two important safety standards from Underwriters Laboratories (UL). In this article, we will provide a comprehensive guide to UL 62368-1:2019 and UL 1699:2020, including their purpose, key requirements, and changes.

What is UL 62368-1:2019?

UL 62368-1:2019 is a safety standard specifically for audio, video, and information technology equipment. It provides guidelines and requirements for manufacturers to ensure that their products meet certain safety standards. Developed by Underwriters Laboratories (UL), an independent global safety science company, UL 62368-1:2019 aims to address the changing landscape of technology and promote safety in the design and manufacturing of electrical equipment.

The Key Requirements of UL 62368-1:2019

UL 62368-1:2019 provides key requirements for manufacturers to ensure that their products meet certain safety standards. The standard outlines several key requirements, including:

Electrical Safety: The standard provides guidelines for electrical safety, including requirements for circuit breakers, fuses, and grounding.

Electrical Conductivity: The standard specifies the minimum electrical conductivity of electrical conductors.

Electrical Overvoltage: The standard sets guidelines for electrical overvoltage, including the use of electrical fuses or circuit breakers.

Radio Frequency (RF) and Microwave: The standard provides guidelines for RF and microwave emissions, including requirements for shielding.

Durability: The standard outlines requirements for the durability of electrical equipment, including requirements for the use of non-destructive testing (NDT).

What is UL 1699:2020?

UL 1699:2020 is an important technical standard from UL that sets the requirements for arc-fault circuit interrupters (AFCIs), also known as arc fault detectors, which are devices used in electrical systems to protect against dangerous arcs and fires caused by electrical faults. The standard specifies the performance, testing, and marking requirements for AFCIs to ensure their effectiveness in preventing electrical fires.

The Purpose of UL 1699:2020

The purpose of UL 1699:2020 is to provide a technical standard for AFCIs, ensuring their performance, reliability, and safety in electrical systems. The standard aims to prevent electrical fires caused by AFCIs, which can be a serious safety hazard.

Key Changes in UL 1699:2020

UL 1699:2020 includes several key changes, including:

AFCI Performance: The standard specifies the performance requirements for AFCIs, including their ability to detect electrical faults and provide a safe electrical path to ground.

AFCI Labeling: The standard requires AFCIs to have label that provides information on their performance, including their ability to detect electrical faults and provide a safe electrical path to ground.

AFCI Testing: The standard specifies the testing requirements for AFCIs, including tests for their performance in different electrical environments.

Conclusion

UL 62368-1:2019 and UL 1699:2020 are both important safety standards that provide guidelines and requirements for manufacturers to ensure that their products meet certain safety standards. UL 62368-1:2019 provides guidelines for electrical safety, while UL 1699:2020 provides a technical standard for AFCIs. By following these.
