Title: Unveiling the Safety Benefits of UL 87 and UL 85: A Comprehensive Guide

Electrical safety is a critical aspect of modern-day living. The use of electrical equipment and appliances is increasingly widespread, making it essential to ensure their safety. two important standards that help achieve this are UL 87 and UL 8In this article, we will discuss the purpose of these standards, their components, and the benefits they provide for the safety of electrical appliances.

What is UL 87?

UL 87, Underwriters Laboratories 87, is a widely recognized standard for insulated wires and cables. It sets guidelines for various characteristics such as insulation thickness, voltage rating, temperature rating, and conductor size. The objective of UL 87 is to ensure the safety and reliability of insulated wires and cables used in electrical systems. By adhering to the standards outlined in UL 87, manufacturers can provide products that meet the minimum safety requirements necessary for their intended applications.

What is UL 85?

UL 85, Underwriters Laboratories 85, is a professional technical standard that pertains to electrical appliances and their safety. It focuses on the testing and certification of electric heating appliances, such as heaters, furnaces, and water heaters, ensuring they meet specific safety requirements. The purpose of UL 85 is to establish safety standards for electric heating appliances, preventing accidents, injuries, and property damage caused by faulty or unsafe appliances.

Key Requirements of UL 85

UL 85, like UL 87, outlines several key requirements that manufacturers must follow to ensure the safety of their products. These requirements include:

Electrical Safety: Appliance should have a low voltage rating and meet the requirements of NEC (National Electrical Code).

Fire Resistance: Appliance should be fire-resistant or have fire-retardant materials.

Electrical Integrity: Appliance should have an enclosure to protect the internal components from electrical hazards.

Electrical Overvoltage: Appliance should have a maximum voltage rating.

Electrical Faults: Appliance should have a circuit breaker or fuse to prevent overcurrent.

Electrical Current: Appliance should have a current rating that is appropriate for the intended use.

Electrical Heat: Appliance should have a thermal management system to prevent overheating.

Electrical Discharge: Appliance should have a discharge path to prevent electrical hazards.

Conclusion

UL 87 and UL 85 are two important standards that ensure the safety of electrical appliances. By adhering to these standards, manufacturers can provide products that meet the minimum safety requirements necessary for their intended applications. By following UL 85 and UL 87, manufacturers can provide consumers with confidence that their products are safe and reliable.
