Ensuring that your water treatment products meet relevant standards helps end-users be confident of a cleaner, safer water supply. Regional requirements vary, but here is a summary of some of the most important standards and guidance that may apply.
While there are many regulations for drinking water, in this article we’ll highlight two key standards that are used to monitor the safety/purity of drinking water treatment chemicals. These are NSF/ANSI/CAN 60 and ABNT NBR 15784:
The Model Aquatic Health Code (MAHC) is a voluntary model pool code created and maintained by the Centers for Disease Control and Prevention (CDC) in the U.S. It is designed to help local, state and regional authorities and the aquatics industry sector reduce the risk of outbreaks, drowning and pool-related injuries.
The MAHC guidelines address every aspect of public pools, from design and construction to maintenance and management of recreational water facilities. The MAHC also includes requirements for pool water treatment chemicals. In summary, these requirements specify that treatment chemicals need to be certified to either NSF/ANSI/CAN 50 or NSF/ANSI/CAN 60:
The U.S. FDA’s Code of Federal Regulations (21 CFR) contains sections that pertain to water treatment products used in food handling and food processing facilities, such as for cooling and retort water. NSF’s nonfood compounds (NFC) registration program, based on 21 CFR, registers water treatment products in the publicly listed White Book™. The registration requirements encompass formulation reviews, testing and evaluation against global food safety program guidelines, which helps ensure that registered products, when used properly, are not posing public health risks.
An important regulation for boiler water treatment chemical manufacturers is the Chemical Inhibitor Approval Scheme (CIAS) in the UK. It is often used as a benchmark by manufacturers and third-party certifiers worldwide.
Chemical inhibitors must meet performance requirements developed by manufacturers, test laboratories and NSF (formerly known as BuildCert). Chemical inhibitors that meet this standard are tested to show that they both restrict the formation of calcium-based scale and reduce metallic corrosion. In addition, testing verifies that the inhibitor is compatible with the non-metallic components typically found in a modern central heating system.
Additionally, NFC category code G6 outlines requirements for treating boiler and steam lines where steam may contact edible food. Not based on efficacy, the registration strictly evaluates that the chemical is safer to use around food.
No matter the end-use application you pursue, you can gain greater product acceptance through NSF certification and/or registration. Our programs address key regional and global requirements for water treatment chemicals, helping to ensure product compliance.
Every day, all over the world, the water treatment industry and regulators use our online listings to find NSF-certified and/or registered products. The NSF mark will show that your water treatment chemicals have been evaluated by an independent third party.
