What is UL 628?

UL 628, also known as the Standard for Safety for Water Conditioning Equipment, is a technical standard established by Underwriters Laboratories (UL), a global safety certification company. This standard specifically applies to water conditioning equipment such as water softeners, deionizers, and reverse osmosis systems.

The Purpose of UL 628

The main purpose of UL 628 is to ensure the safety and performance of water conditioning equipment in order to protect consumers and property. This standard sets forth specific requirements that manufacturers must meet during the design, construction, and testing of their products. Compliance with UL 628 is often a prerequisite for the sale and distribution of water conditioning equipment in many markets.

Key Requirements of UL 628

UL 628 covers a wide range of criteria that water conditioning equipment must meet. First and foremost, it requires compliance with electrical safety standards to prevent hazards such as electric shock or fire. This includes testing for insulation resistance, grounding, and protection against electrical leakage.

Additionally, UL 628 sets requirements for the mechanical integrity of water conditioning equipment. This includes materials used, structural strength, and resistance to pressure and temperature. Manufacturers are also required to provide clear instructions and warning labels to ensure proper installation, operation, and maintenance of the equipment.

The Benefits of UL 628 Compliance

Compliance with UL 628 not only ensures safety but also provides several benefits for manufacturers and consumers alike. For manufacturers, compliance with this standard can enhance their reputation and credibility in the market, as it demonstrates their commitment to product safety and quality. It may also simplify the certification and approval process, allowing for easier access to global markets.

For consumers, the presence of the UL 628 certification mark on a water conditioning equipment indicates that the product has undergone rigorous testing and meets recognized safety standards. This provides peace of mind and assurance that the equipment is reliable and safe to use.
