What is UL 658?

UL 658, also known as the Standard for Safety of Industrial Control Equipment, is a widely accepted standard in the industry that sets guidelines and requirements for the design and manufacturing of industrial control equipment. This standard is developed and published by Underwriters Laboratories (UL), an independent global safety science company.

The Purpose of UL 658

The main purpose of UL 658 is to ensure the safety and reliability of industrial control equipment used in various industries such as manufacturing, automation, and process control. It provides manufacturers with guidelines on how to design and construct their equipment to meet specific safety requirements, including electrical, mechanical, and fire safety standards.

The Requirements of UL 658

UL 658 outlines several key requirements that industrial control equipment must meet. These requirements cover a wide range of criteria, including electrical insulation, temperature ratings, protection against fire and electric shock hazards, and mechanical resistance. The standard also includes requirements for marking and product documentation, to help users and authorities identify compliant products.

The Benefits of Complying with UL 658

Complying with UL 658 brings several benefits for manufacturers and end-users alike. First and foremost, it ensures the safety of the equipment, reducing the risk of accidents or malfunctions that could lead to injuries or property damage. Compliance with UL 658 can also enhance the reputation and credibility of manufacturers, as it demonstrates their commitment to meeting high safety standards. Additionally, using UL 658-compliant equipment can simplify regulatory compliance efforts for end-users, who can be confident in the reliability and safety of the products they purchase.
