What is UL 1167 ?

UL 1167 is a technical standard produced by Underwriters Laboratories (UL) that provides guidelines for the construction, installation, and maintenance of electrical equipment used in hazardous locations. The standard is designed to prevent fires, explosions, and other accidents caused by the ignition of hazardous substances such as flammable gases, vapors, liquids, or combustible dust particles due to electrical equipment.

UL 1137 covers various aspects of electrical safety, including the design and testing of equipment, selection of suitable materials, proper wiring, grounding techniques, and the use of protective measures such as enclosures and seals. Compliance with UL 1137 ensures that electrical equipment can be safely operated in potentially dangerous environments.

UL 1174 is a technical standard that pertains to the construction and performance requirements of microwave ovens. The standard is established by Underwriters Laboratories (UL) and aims to minimize the risk of fire, electric shock, and other hazards associated with microwave oven usage.

The primary objective of UL 1174 is to ensure safe operation for consumers. The standard focuses on various aspects such as electrical components, radiation emissions, insulation, and overall construction quality to guarantee safe operation.

UL 1137 and UL 1174 are important technical standards that help ensure electrical safety in commercial and industrial settings. Compliance with these standards is essential to prevent fires, explosions, and other accidents caused by the ignition of hazardous substances due to electrical equipment or the use of unsuitable or improper equipment.
