Title: What is UL 860 and UL 859? A Comprehensive Guide

When it comes to electrical safety, it is essential to have proper regulations and standards in place to ensure the safety of consumers. The two most important standards in this field are UL 860 and UL 859, which are widely recognized in the industry. In this article, we will delve into the details of both standards, UL 860 and UL 859, providing a thorough understanding of their importance and implications.

What is UL 860?

UL 860 is a widely recognized standard in the field of electrical safety. It specifies the requirements and tests for electrical cords, cord sets, power supply cords, and plug-connected power supplies. The purpose of UL 860 is to ensure that these products meet the necessary safety standards, including electrical fires, electrical injuries, and other electrical hazards.

Key Components of UL 860

UL 860 is divided into four categories, which cover different aspects of electrical safety. These categories include:

Electrical Safety Information: This category includes requirements for labeling, warning, and other information to help consumers understand the electrical hazards associated with the product.

Electrical Performance and Discharge Test: This category includes requirements for testing the electrical performance and endurance of the product, such as the amount of time it can withstand without a fault.

Electrical Safety Tests: This category includes requirements for testing the electrical safety of the product, such as the amount of current it can safely handle without a fault.

Electrical Safety Requirements for Controllers and Contactors: This category includes requirements for controllers and contactors, such as the use of insulated or non-insulated wiring.

UL 860 Test Requirements

To ensure that a product meets the requirements of UL 860, it must undergo various tests. These tests include:

Electrical Safety Test: This test is designed to verify that the product can withstand electrical hazards, such as electrical fires or electrical injuries.

Electrical Performance Test: This test is designed to verify that the product can perform as expected and meets the necessary electrical performance requirements.

Electrical Safety Test for Controllers and Contactors: This test is designed to verify that controllers and contactors meet the necessary safety requirements, such as the use of insulated or non-insulated wiring.

Third-Party Testing: This test is designed to verify that the product meets the requirements of other recognized standards, such as NEMA or IEC.

UL 859 and Its Importance

UL 859 is a widely known standard in the electrical industry that focuses on safety requirements for electrically heated blankets. The purpose of UL 859 is to ensure the safety of electrically heated blankets, which are available in the market.

Key Requirements of UL 859

UL 859 sets forth rigorous testing procedures and performance requirements that manufacturers must adhere to in order to obtain UL certification for their products. The following are the key requirements of UL 859:

Electrical Safety: The product must meet the requirements of NEC 5084.2, which covers electrical safety in general, including electrical fires, electrical injuries, and other electrical hazards.

Electrical Performance: The product must perform as expected and meet the necessary electrical performance requirements, such as the amount of time it can withstand without a fault.

Electrical Safety Controls: The product must include electrical safety controls, such as circuit breakers or fuses, to prevent electrical hazards.

Electrical Safety Test: The product must undergo various tests to verify that it meets the requirements of UL 859, including electrical safety tests for controllers and contactors.

Conclusion

UL 860 and UL 859 are two.
