At our test facilities we do extensive testing of every product in every stage of the project. The only way to fully understand and to be sure of your product are through testing, testing and more testing.
External companies are used to do the final testing for the purpose of ATEX/ex -certification. We want you as our customer not to rely on our word alone. We however have the greatest confidence in our own products so the use of external companies for testing is something we encourage.
