What is UL 924Ed10?

UL 924Ed10 is a technical standard published by Underwriters Laboratories (UL) that outlines the requirements for safety in the design and manufacturing of industrial equipment, including but not limited to, transformers, switchboards, and power control equipment. The standard, which is also known as the Standard for Household Electric Coffee Makers, is designed to ensure the safety and functionality of these popular household appliances.

The primary purpose of UL 924Ed10 is to establish safety requirements and test procedures for electrical equipment. It covers various aspects of equipment design, including electrical components, heating elements, automatic shut-off features, and other functional aspects. By complying with UL 924Ed10, manufacturers can ensure that their equipment is safe to use and meets the necessary quality standards.

Key Requirements of UL 924Ed10

UL 924Ed10 has several key requirements that manufacturers must comply with in order to achieve certification. These requirements include:

Electrical Safety: The standard must ensure that the equipment is free from electrical hazards, such as electrocution, overheating, and electrical fires.

Fire Resistance: The equipment must be able to withstand a fire for a specified period of time, as determined by the standard's testing procedures.

Electrical Conductivity: The equipment's electrical conductivity must be within specified limits, which are based on the equipment's intended use and the materials used in its construction.

Enclosure: The equipment's enclosure must be designed to prevent electrical hazards and protect the equipment from environmental factors such as moisture, dust, and extreme temperatures.

Maintenance and Repairs: The manufacturer must ensure that the equipment is properly maintained and repaired, and that any necessary repairs are performed by qualified technicians.

UL 924Ed10 and UL 942

UL 924Ed10 and UL 942 are both standards published by UL that are essential for ensuring the safety and functionality of electrical equipment. UL 924Ed10 is focused on the safety of industrial equipment, while UL 942 is focused on the fire safety of electrical equipment.

UL 924Ed10 is used to assess the safety of electrical equipment, including transformers, switchboards, and power control equipment. It sets out specific criteria for determining the ratings of these materials based on their resistance to ignition, flame spread, and self-extinguishing properties.

UL 942 is used to ensure that electrical equipment is fire-resistant. It provides guidelines and certifications for flammability ratings of materials used in electrical enclosures, such as cabinets and control panels. The standard sets out specific criteria for determining the ratings of these materials based on their resistance to ignition, flame spread, and self-extinguishing properties.

By obtaining UL 924Ed10 or UL 942 certification, manufacturers can demonstrate their commitment to producing high-quality, fire-resistant electrical equipment that meets the necessary safety and quality standards.
