Public health organisation NSF International has introduced NSF REG4, an independent certification programme that enables manufacturers of food equipment, plumbing products and materials to demonstrate compliance with the UK’s Water Supply (Water Fittings) Regulations of 1999 and with equivalent water regulations in Scotland and Northern Ireland.
NSF REG4 certifies mechanical products and non-metallic materials that are in contact with drinking water, including: valves, backflow prevention devices, taps, mixers, shower heads, pipes and fittings, tanks, cisterns and water meters, rubbers, coatings, cements, resins and sealants.
The certification is the new reference programme for the UK market. Just like in many other parts of the world, manufacturers must comply with country-specific regulations to sell their products. NSF feels its expertise in the water industry allowed it to work in transparency with the UK water industry, regulators and trade associations to develop the NSF REG4 certification programme, which enables a route to compliance.
The programme offers manufacturers looking to introduce or sell products in the UK an audit-based program to verify compliance and sustain quality products through better control of the supply chain. As part of the certification process, production facilities undergo annual audits to review processes and systems based on the NSF REG4 certification requirements.
NSF REG4 is also designed to enable timely access to the UK market. NSF can specify testing without waiting weeks for WRAS review. NSF’s independent certification decision immediately following product testing should allow manufacturers to see shorter timeframes for product listing and market access.
All REG4 product testing is conducted at NSF’s International ISO/IEC 17025-accredited, water laboratory in Oakdale, Wales. NSF International’s certification program in Wales is also ISO/IEC 17065 accredited by UKAS (United Kingdom Accreditation Service). This international standard contains requirements for the competence, consistent operation and impartiality of product, process and service certification bodies.
