As an independent, fully accredited testing body, Element provides 3A sanitary testing for dairy standards by testing multiple-use plastic and rubber materials used as product contact or cleaning contact surfaces for dairy equipment. Our Engaged Experts test under accelerated use-simulating conditions to help you make certain that the materials and products that you make are safe to use in typical dairy processing operations. 

3A sanitary testing requires that any plastic or rubber-like material that comes in contact with product or cleaning solutions (liquid product hoses, food conveyor belts, and gaskets for pipelines and equipment) shall be tested to meet the performance criteria for their intended use as outlined in 3A Sanitary Standards. For the dairy industry, this covers products involved in the production, processing and packaging of milk, milk-based products and other perishable goods.
