What is NSF Standard 61?
The NSF Water Distribution Systems Program is responsible
for the Certification of drinking water treatment chemicals
and drinking water system components to ensure that these
products do not contribute contaminants to drinking water
that could cause adverse health effects.
NSF Standard 61 Drinking Water System Components – Health
Effects is the nationally recognized health effects standard
for all devices, components and materials which contact drinking
water.

3A Sanitary Approved
Orings
This standard is formulated by "The
International Association of Milk, Food and Environmental
Sanitarians, U.S. Public Health Service, The Dairy Industry
Committee". These sanitary standards cover rubber
materials intended for multiple-use as product contact surfaces
or solution contact surfaces in the production, processing
and handling of milk or milk products. Test
procedures and criteria are also provided for rubber materials
as a means of determining their ability to be cleaned and
to receive effective bactericidal treatment or steam sterilization
and to maintain their essential properties.
