The 4MS initiative, created by four EU member states: France, Germany, the Netherlands and the UK, was created in response to the need to harmonize standards for materials used in contact with drinking water. In response to the European Commission's withdrawal of support for the European Acceptance Scheme (EAS), these countries decided on their own to work on common hygienic assessment standards that would support the safety of drinking water from source to tap.

why brass?
Brass, traditionally used in water systems for its antimicrobial properties and durability, is one of the main materials being reevaluated under the 4MS initiative. The changes are motivated by the need to comply with new European Union regulations aimed at increasing the hygienic performance of materials in contact with drinking water, as well as to remove trade barriers resulting from differences in national certification systems(European Drinking Water).
What does the 4MS common departure mean?
Under the "Common Approach," the four member states have committed to harmonizing testing methods and requirements for products in contact with drinking water. All materials, such as brass, are subject to rigorous testing to make sure they are safe for the health of users. The exact guidelines for these tests are being developed jointly, with the goal of a uniform level of protection for drinking water quality in these countries.

positive list - a new standard for brass
One of the most important elements of the joint approach is the introduction of the so-called "positive list," which includes ingredients and materials approved for contact with drinking water. Brass, as one of the key materials, will also undergo this evaluation. The list is regularly updated and published, allowing manufacturers to comply with the latest requirements.
benefits for consumers and manufacturers
For consumers, the introduction of uniform standards means greater safety and peace of mind, knowing that the products used comply with the highest hygiene standards. For manufacturers, it's an opportunity to bring products up to international standards, which can help make them more competitive in the European market.
summary
Changing the materials used, such as brass, in products in contact with drinking water is a necessity driven by the desire to ensure the highest quality and safety. The 4MS initiative, through cooperation and harmonization of tests and requirements, makes it possible to achieve these goals while protecting public health and fostering innovation in the water supply sector.
