WRAS Certificate

WRAS (Water Regulations Advisory Scheme) is the authoritative safety certification for drinking water contact products and materials in the UK. It serves as a compliance certificate for water utilities entering the UK and the Commonwealth markets.
I. Core Positioning
• Full Name: Water Regulations Advisory Scheme (Water Regulations Consultation Program)
• Authority: WRAS Ltd. of the United Kingdom (Managed by WRc-nsf, the UK Water Research Institute)
• Legal basis: "Water Supply (Water Fittings) Regulations 1999" and other British water supply regulations
• Main objective: To prevent water pollution, backflow, waste, and ensure the safety of public drinking water.
• Applicable regions: United Kingdom (England, Wales, Scotland, Northern Ireland), and widely adopted and referenced by multiple countries
II. Two Types of Certifications (Key)
1. Materials Approval
• Object: All non-metallic materials that come into contact with drinking water (such as silicone, rubber, plastic, coatings, lubricants, etc.)
• Test standard: BS 6920 (Core)
• Test Content:
◦ Do not release toxic substances (such as heavy metals and organic compounds)
◦ Does not affect the color, odor or taste of the water
◦ Does not breed microorganisms
Resistant to water aging and without causing degradation or pollution.
• The silicone you are concerned about: It must first pass the material certification process before it can be used in water-related products such as faucets, valves, and baby nipples.
2. Product Approval
• Object: Complete finished products (toilets, valves, pipes, water meters, water heaters, bathrooms, etc.)
• Test Content:
Material Safety (including material certification)
◦ Mechanical properties (pressure resistance, leak prevention, lifespan)
◦ Prevent backflow (prevent sewage from flowing back into the main water channel)
Water conservation and prevention of misuse
III. Key Points of the Certificate
• Validity period: 5 years. Renewal and re-certification are required upon expiration.
• Official Directory: Approved products are included in the "Water Fittings and Materials Directory" (updated annually in April or October)
• Unique Number: Each certification has an independent number, and its authenticity can be verified on the official website.
• Usage Mark: After approval, the label "WRAS Approved" can be printed.
IV. Why It Matters (For Silicone/Water-Resistant Products)
1. UK Regulation: Without WRAS certification, it cannot be used in the UK public water supply system.
2. Global recognition: Widely accepted by the European Union, the Middle East, Australia, Singapore, etc.
3. High-end market threshold: Quality endorsement for food, medical, and water treatment products
V. Comparison with Common Certifications (Summary Table)
• WRAS: British Water, BS 6920, focusing on drinking water safety
• FDA: US Food Contact, focusing on indirect food contact
• KFWS: German Water Supply, focusing on water safety for metals/plastics exposure
• ACS: French Water, French Market Access
