In this Water Vlog, Vincent Boks, Managing Director EMEA Water Division, NSF, discusses the recently introduced NSF P524 Water Quality Testing Devices for Drinking Water protocol and the NSF Guideline 533 – Ingredients Used in Drinking Water Products.
He also explains the crucial work that the organisation carries out in terms of testing and approval of materials, systems and chemicals for water treatment solutions, with greywater recycling technology an increasingly important focus.
P524 is the first-ever protocol that provides a standard third-party validation of the performance of water quality testing devices (WQTD) used in drinking water, ensuring public health protection by providing assurance that these crucial devices perform according to the manufacturer’s claims.
The new protocol has been developed through collaboration between NSF’s leading experts and industry experts including manufacturers and public health officials. Until now, manufacturers of potable water WQTDs could only advertise performance claims based on their own validation testing.
NSF P524 covers any device, sensor, or test kit used to measure water quality parameters in drinking water where the operation of the kit does not require access to lab facilities or equipment and provides results in real-time or after a short wait period. The protocol verifies the manufacturer’s claimed accuracy and precision for the device across its claimed operating range. Certification testing verifies the claims by comparing measurements taken with the device to established laboratory reference methods.
