3A Sanitary Testing for Dairy Contact Surfaces

Elements' testing capabilities cover all plastic and rubber materials used in dairy processing equipment, including product contact surfaces and cleaning contact surfaces. We evaluate materials under accelerated use conditions to simulate real-world dairy processing environments, focusing specifically on materials used in the production, processing, and packaging of milk and milk-based products. 

• Multiple-use plastic materials for dairy contact surfaces 

• Rubber and rubber-like materials used in dairy equipment 

• Food-grade gaskets, seals, and sealing components 

• Materials used for liquid product handling 

• Materials for cleaning system contact surfaces 

• Heat-resistant materials for dairy applications 

We perform comprehensive physical property testing, including heat aging, water absorption, and fluid exposure, to evaluate material performance in dairy processing conditions. These tests ensure materials withstand prolonged exposure to heat, moisture, and cleaning agents, which is crucial in high-performance dairy applications; all under conditions that simulate real-world wear and stress. Our testing services include: 

• Heat aging of plastics without load (ASTM D3015) 

• Water absorption analysis (ASTM D570) 

• Durometer hardness Shore A and B measurements (ASTM D2240) 

• Specific gravity testing (ASTM D792) 

• Fluid exposure evaluation for rubber (ASTM D471)

Our testing approach combines accelerated use simulation with extensive materials analysis to evaluate physical properties and performance characteristics, simulating long-term use in dairy environments to ensure continued safety and compliance under rigorous operational conditions. We deliver accurate, first-time-right data that demonstrates compliance with 3A Sanitary Standards. Our comprehensive testing helps maintain essential functional properties throughout typical dairy processing operations, validating long-term performance.
