NSF Launches NSF P535 for Drinking Water Treatment Units in China

Shanghai, China – NSF, the leading testing and certification organization in the water industry, announced today the launch of a new protocol in China, NSF P535: Drinking Water Treatment Units – Filtration. The protocol establishes minimum requirements for material safety and performance of point-of-use (POU) water filters. Certification to NSF P535 means that a third party has evaluated the product and meets the strict requirements of the protocol.

NSF developed NSF P535 to fill the local market demand for protocol requirements for drinking water treatment systems and components in China. The new protocol covers the basic requirements for material safety and performance of domestic point-of-use (POU) drinking water systems in China, including health-related reductions for specific contaminants such as lead, mercury, hexavalent chromium, perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), bisphenol A (BPA) and more. The products covered by the protocol include purified water filters (reverse osmosis and nanofiltration), general water filters (ultrafiltration, activated carbon filtration, ceramic filtration, etc.) and other equipment (pre-filters and water softeners).

The NSF P535 test method is based on relevant Chinese regulations and NSF standards for drinking water treatment. Certification to this new protocol will help manufacturers prove their products' quality and performance, differentiating them in the competitive water filter market.

"We are excited to launch NSF P535, as certification will help verify that drinking water treatment products meet the performance and safety requirements outlined in domestic drinking water standards,” said Shan Yulong, Managing Director of China, NSF. “Products that earn certification will be listed on NSF’s official website and able to use the unique Chinese certification mark. We look forward to working with local manufacturers to certify their products and help provide consumer confidence throughout China’s drinking water treatment units industry."

NSF P535 testing and certification is conducted in NSF's local partner laboratories in China, saving clients transportation time and costs. In addition, this localized approach offers manufacturers a one-stop certification process that covers material and performance testing, certification and auditing. This makes certification more efficient and cost-effective, which can help manufacturers seeking certification better control their new product development cycle and enhance product quality.

"Since entering the Chinese market in 2005, NSF has been dedicated to providing our clients with customized and responsive services to our clients. By passing NSF’s testing and certification, clients can prove to their consumers that their products are credible, and their claims verified," said Dave Purkiss, Vice President of Water, NSF. “We look forward to continuing our work in China, collaborating with relevant industry associations, working with manufacturers to verify their product claims, and fulfilling our mission of improving human and planet health."

NSF's water services in China include certification services for drinking water treatment, plastic pipes, municipal water supply, product testing, and customized testing.

About NSF

NSF is an independent, global services organization dedicated to improving human and planet health for more than 80 years by facilitating standards development and providing world-class testing, inspection, certification, advisory services, and digital solutions to the food, water, health sciences, and consumer goods industries. NSF operates in 180 countries and is a World Health Organization (WHO) Collaborating Center on Food Safety, Water Quality and Medical Device Safety.

NSF’s Water Division provides risk assessments, testing, inspection, and certification services for the water industry from source to tap. NSF facilitated the development of the American National Standards for all materials and products that treat or come in contact with drinking water to help protect public health and the environment and minimize adverse health effects. In 1990, the U.S. EPA replaced its own drinking water product advisory program with these NSF standards.
