Kiwa carries out investigations for manufacturers of rubber compounds and rubber products, distributors and traders, designers, manufacturers and constructors of installations and equipment, maintenance and asset management.

The choice of the right rubber material and the proper composition of the rubber compound is therefore important. Many material and product specifications have a requirement for the ozone resistance. The ozone resistance of rubber is commonly tested at standard test conditions according to ISO 1431-1, ASTM D1149 or DIN 53509-1. Kiwa's laboratories have the necessary special test equipment for the investigation of the ozone resistance. Besides rubber, other products and materials as well can be tested for the influence of ozone in these test facilities.

Examples: rubber seals, cables, hoses, colour fastness of textile products.

Ozone resistance testing of rubber is important for the choice of the right rubber material for a seal, for the evaluation of the product quality and for the cause analysis of possible failures.
