NSF International announces the availability of a new reference guide to help drinking water treatment system manufacturers understand the new European Committee for Standardization (CEN) Standards. The new standards have been in development since 1994 and NSF participated in technical reviews and discussions during this process. The standards cover a wide range of treatment technologies and contaminant reduction claims.For more information, or to download a free copy of the reference guide, visit NSFs website at http://www.nsf.org/info/dwtu-download.
