Australian Standards for Tapware: AS/NZS 3718 Explained

Tapware might seem simple, but in Australia, it must meet stringent technical requirements. The primary standard governing TAPWARE is AS/NZS 3718:2005, titled "Water supply - Tap ware" . This comprehensive standard specifies requirements for a wide range of products including metallic taps, plastic taps, mixing taps, sensor taps, lever taps, and tap sets in nominal sizes from DN6 to DN50 . These products are generally designed for continuous operating temperatures not exceeding 80°C, though products for other temperature ranges are included when tested appropriately . The standard ensures that tapware performs reliably, resists corrosion, and maintains water quality. Importantly, AS/NZS 3718 works in conjunction with the Watermark scheme—tapware must comply with this standard to achieve Watermark certification . Additionally, water-efficient tapware carries WELS ratings, helping consumers identify products that save water without sacrificing performance . When selecting tapware for your Australian home, always verify compliance with AS/NZS 3718 through Watermark certification, ensuring your fixtures meet the highest standards of safety, durability, and performance.
