Rubber ozone resistance test
Kiwa carries out ozone resistance tests of rubber according to international standards.
Rubber materials and products undergo a deformation during service. This deformation is an elongation or a compression. The outer rubber surface is strained in both situations. Many rubber materials are susceptible to ozone attack, that leads to the generation of small cracks in the rubber outer surface. Eventually the rubber product can fail.
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
Who is this for?
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.
When is this needed?
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.
For the quality assurance of rubber products you can rely on the services of Kiwa. Besides certification schemes we can offer you technical support. You can call our rubber specialists of the Expert Centre Polymers for questions about service life, failure analysis and laboratory test services.
It is important to know that the Kiwa Expert Centre Polymers is part of Kiwa Technology that acts as a separate company, independent form the Certification Divisions within the Kiwa Group.
