3-A Sanitary Standard (Dairy)

PPE manufactures O-ringshygienic gaskets and custom-designed seal components in accordance with 3-A Standard 18-03 “3-A Sanitary Standards for multiple-use rubber and rubber-like materials used as product contact surfaces in dairy equipment”, defining requirements for food quality materials that must also be suitable for cleaning and sanitising solutions.

Formed by the US food and Dairy industry, 3-A Sanitary Standards Inc. defines specifications and best practice for the design, manufacture, installation and use of hygienic equipment. As with FDA, the 3-A standards are adopted on a worldwide basis.

All PPE’s 3-A Sanitary Standards approved elastomers are FDA-compliant to FDA CFR21.177.2600, free from animal derived ingredients (ADI-free), resistant to steam sterilisation, milk fat and water, acid and alkali cleaning solutions and chlorine sanitising solution.

PPE elastomers meeting the 3-A standard include NBREPDMSiliconeHNBRFKM and FFKM, allowing equipment manufacturers/users to select the most appropriate elastomer to temperature, chemical and physical performance criteria.
