Nkiwa:
Kiwa is an independent international organization that offers highly qualified certifications. Kiwa supports these certification activities with inspection, inspection, examination, technological knowledge, research, training and data services. Kiwa is the market leader in the areas of (drinking) water, gas and construction, industry, company services as well as healthcare and security. The Kiwa water sign can be used by certificate owners before and on products that come into contact with drinking water and meet all the requirements of the relevant KiWa evaluation guidelines (BRLS).
BAM:
BAM is a quality sign for seals. The reactivity of a package material with oxygen at high pressure and increased temperature is evaluated. If the look, mass and autogenic lick temperature of the material do not change, it is considered aging resistant
KTW:
The KTW directive (Germany) describes test procedures and health standards for plastics that come into contact with drinking water. It reflects the current state of scientific and technical knowledge with regard to the hygiene requirements that can be met by organic materials that come into contact with water (drinking water) for human use.
FDA:
The Food and Drug Administration, FDA for short, is the authority of the Federal Government of the United States, which controls the quality of food and drugs in the broadest sense.
EN 681-1:

W534:
This is very important for manufacturers of high-quality water and heating devices, they get a good and reliable impression of the expected lifespan of the O-rings in their products. DVGW has developed an additional test W534 to predict the expected lifespan of O-rings (compression set (rubber memory) tests are carried out at real O-rings for up to 5000 hours at 110 ° C in water !!! not on test plates 24 or 70 hours at 70 ° C (Sulfer Cured EPDM) in air)
W270:
The quality sign W270 means that product components that come into contact with drinking water have been checked and approved by German laboratories (TZW and DVGW) according to the recommendations of the UBA (Federal Environmental Office).
EFSA:

With a DVGW certificate, product manufacturers, specialized companies, supply companies and experts can prove to their customers and market partners that they meet the state of the art in the field of activities.
ACS:
ACS certification (DESTESTITION de conformite Sanitaire) The approval for material security for products and components that come into contact with drinking water is carried out by ACS certification. The ACS certificate for sanitary conformity was introduced in 1998. The Ordinance ensures that components that come into contact with drinking water do not cause organic deterioration, change the organoleptic properties of water and the growth of microphone support organisms and the release of poisonous substances in the water.
REACH:
REACH is a European Ordinance that relates to the production, import and use of chemical substances as such or substances contained in preparations. The abbreviation stands for registration, evaluation, approval and restriction of chemicals.
