NBR has Passed the NSF/WARS Certification Testing
NBR (Nitrile Rubber) certified to NSF/ANSI 61 and WRAS (BS 6920) for drinking water safety, essential for water-contact seals and components. NSF/ANSI 61, the North American standard, limits heavy metals, organic contaminants, and odor release from NBR, mandatory for US and Canadian market access. WRAS, based on UK BS 6920, serves the UK, EU, and Commonwealth, focusing on long-term water stability, microbial safety and taste control with formula disclosure and annual factory audits. Both certifications verify NBR’s non-toxicity, hygiene, and stability, ensuring compliance with global drinking water regulations and enhancing competitiveness and trust worldwide.
