3-A Standard 18-03 for Rubber Seal Materials.
Standard 18-03 “3-A Sanitary Standards for multiple-use rubber and rubberlike materials used as product contact surfaces in dairy equipment” defines requirements for food quality materials that must also be suitable for cleaning
and sanitising solutions. |
| |
| All PPE’s 3-A Sanitary Standards compliant elastomers are FDAcompliant to FDA CFR21.177.2600, resistant to steam sterilisation, milk fat and water, acid and alkali cleaning solutions and chlorine sanitising solution. |
| |
| The PPE elastomers meeting the 3-A standard include fluorocarbon, silicone, EPDM and nitrile, allowing manufacturers to select the most appropriate elastomer to temperature, chemical and physical performance criteria. |
|
The key criteria are:
- FDA compliance (to FDA CFR21.177.2600)
- Resistance to steam sterilisation.
- Resistance to milk fat and water.
- Minimum heat ageing properties.
- Minimum physical properties (tensile strength and elongation at break).
- Resistance to acid, alkali cleaning solutions
- Resistance to chlorine sanitising solution.
