KTW certification

KTW certification

What is KTW certification? Drinking water is one of the most controlled food products. The product materials in contact with drinking water can generate microbial growth and impurities/contaminants. This, in turn, creates a serious health risk and also a threat to the environment. KTW (Plastics in Drinking Water) KTW (plastics in drinking water, Kunststoff-Trinkwasser) is a publication of the German […]

ISO3601-3

ISO3601-3: Quality acceptance criteria ISO3601-3 defines the quality acceptance criteria for O Rings used in fluid systems, the sizes of which are standardized in ISO3601-1 and ISO3601-2. This section of ISO3601 additionally specifies and classifies surface deficiencies on O Rings and defines the maximum satisfactory limit for these deficiencies. ISO3601-3 is also suitable to O Rings used in aerospace construction. […]
