For any product that comes into contact with drinking water-such as 5 in 1 taps, water filters, and under-sink drinking systems-certification is essential. It is not only about legal compliance in different countries but also about building trust with consumers by proving safety, durability, and quality. Certifications test products against strict hygiene, mechanical, and material standards, ensuring that water remains pure, safe, and free from harmful substances.
The WRAS (Water Regulations Approval Scheme) certification is widely recognized in the UK. While not legally mandatory, it has become the de facto requirement for entry into the British market.
- Hygiene Testing (BS 6920): Ensures that no harmful substances such as heavy metals (lead, cadmium) or organic compounds (plasticizers) migrate into drinking water, and that taste, odor, or color are not affected.
- Mechanical Testing: Covers durability against aging, water hammer, and stretching. Products are tested at different temperatures (23°C, 60°C, 85°C) and pressures (5 bar, 10 bar).
- Non-Metal Materials: Must be opaque when exposed to sunlight to prevent microbial growth.
- Validity: Certification is valid for 5 years.
Germany is known for its highly structured certification system:
KTW-BWGL (Hygiene Standard): Mandatory for all non-metal components in contact with drinking water.
UBA Guidelines (Metal Materials): Sets strict limits on the use of metals in water-contact materials.
EN 16421 (Microbiological Testing): Replaced W270 for microbial resistance testing.
DVGW (Mechanical Testing): Products must pass performance tests such as EN 13618 or W543 for pipes and hoses.
Validity: Both certifications last 5 years.
This combination ensures both material safety and mechanical durability.
France enforces ACS certification, mandatory for all drinking water products:
- Non-Metal Components: Must comply with ACS hygiene standards.
- Metal Components: Must meet 4MS requirements (European criteria for safe metallic materials).
- Mechanical Standards: Differ by product type:
Inlet pipes: EN 13618
Pull-out hoses: EN 16146
Shower hoses: EN 1113
- QB Certification: A complementary certification for inlet pipes, requiring ACS + 4MS + EN 13618.
- Validity: 5 years.
The original EU Directive 98/83/EC led to fragmented national certifications. This created complexity for manufacturers entering multiple EU markets.
Since January 2021, the new EU Directive (2020/2184) unified certification requirements, ensuring that once certified, a product can be sold across all EU member states without additional national testing.
From 2033, the EU Drinking Water Directive (DWD), supported by Minimum Hygiene Requirements (MHR), will apply across all EU Member States.
Existing national schemes (such as KTW in Germany or ACS in France) are being harmonised under this framework.
As the UK is no longer part of the EU, national requirements, such as WRAS approval, remain applicable to products entering the UK market.
This change greatly benefits international buyers of ODM 5 in 1 taps and drinking water systems, simplifying compliance.
North American certification is built around lead control and safety:
- NSF/ANSI 61 (Hygiene): Ensures no harmful substances leach into water.
- NSF/ANSI 372 (Lead-Free): Requires weighted average lead content ≤ 0.25%.
- Q Value (Lead Extraction): Must remain under 0.5 μg/L.
- Mechanical Standards: ASME A112.18.6 / CSA B125.6 applied in the US and Canada.
- UPC vs. cUPC: UPC is for the US, while cUPC covers both US and Canada.
- Validity: 5 years.
For premium kitchen taps and under-sink systems, UPC/cUPC is critical for entering the North American market.
Australia enforces the WaterMark (WMK) certification, which is:
- Hygiene Standard: AS 4020
- Lead-Free Compliance: Weighted average ≤ 0.25%
- Dezincification Resistance: Metals must meet AS 2345 standards.
- Mechanical Testing: AS 3499, though not always mandatory.
- Temperature Classification: Products under 70°C must be labeled "L," while those up to 90°C require "H."
- Validity: 5 years.
This local certification ensures that imported 5 in 1 taps are safe, durable, and compliant with Australian drinking water safety laws.
Modern 5 in 1 boiling, chilled, and sparkling water taps combine multiple functions in one product, making certification even more important.
- Consumer Trust: Certifications prove water quality and product safety.
- Market Access: Without certification, entry into key regions is impossible.
- Brand Reputation: ODM buyers and distributors rely on certified products to build long-term consumer confidence.
- ODM Partnerships: Brands working with certified manufacturers like Smart Water Tech save time and reduce risk when entering regulated markets.
