Guideline for Hygienic Assessment of Elastomers in Contact With Drinking Water
Beginning in 2016, products using peroxide cured EPDMs which had obtained conditional approvals will expire and those products seeking approval will be unable to contain peroxide cured EPDMs. Peroxide cured EPDMs are considered not to have a full toxicological evaluation and therefore are no longer permitted in the German Positive List (GPL). This means that materials or products sold in Germany may not be made with or use peroxide cured EPDM. Products currently certified to KTW or DVGW will not be re-approved after 2016 and will have to be reformulated. Another certification cannot be used in place of conformance to the GPL.
NSF does not offer German approvals directly, but can help customers obtain German approval via the NSF Passport program. For more information, please email firstname.lastname@example.org.
To view the GPL, please see the Elastomer Guideline.
