What is UL 696?

UL 696 is a technical standard set by Underwriters Laboratories, a global safety consulting and certification company. This standard specifically focuses on the requirements for industrial control panels and electrical control equipment used in hazardous locations. In this article, we will explore the various aspects of UL 696 and its significance.

Scope and Purpose

The scope of UL 696 covers the design, construction, testing, and certification of industrial control panels and associated electrical control equipment intended for use in potentially explosive atmospheres. This standard ensures that these products meet the necessary safety requirements and prevent any potential risks of fire or explosions in hazardous environments.

Key Requirements

UL 696 outlines several key requirements that manufacturers need to meet in order to obtain certification for their industrial control panels. These include:

Proper enclosure and wiring methods to minimize the risk of igniting flammable gases, vapors, or dust

Appropriate labeling for identification of hazardous locations

Effective grounding and bonding techniques to prevent buildup of static charges

Protection against excess temperature rise, overcurrent, and short circuits

Compatibility with other electrical devices and components

Benefits of UL 696 Certification

UL 696 certification offers several benefits to both manufacturers and end-users. Firstly, it demonstrates compliance with industry safety standards, providing assurance to buyers that the product has undergone rigorous testing and evaluation. This enhances the credibility and marketability of the manufacturer's products.

Additionally, UL 696 certification helps manufacturers expand their market reach since many industries (such as oil and gas, chemical, and pharmaceutical) require equipment that meets this standard. By obtaining this certification, manufacturers can enter new markets and increase their customer base.

For end-users, UL 696 certification ensures the safe operation of industrial control panels and electrical control equipment in hazardous locations. It mitigates the risk of accidents, injuries, and property damage due to electrical malfunctions or failures.

In conclusion, UL 696 plays a vital role in ensuring the safety and reliability of industrial control panels and electrical control equipment used in hazardous locations. By complying with this standard, manufacturers can provide high-quality products that meet the industry's safety requirements, while end-users can have peace of mind knowing that these products are tested and certified for use in potentially explosive atmospheres.
