Certification is definitive unless a major change is made on the device: hardware, software.
One shot fee paid upfront to the Test Center (to be negotiated with test center).
1. The Applicant fills in the Application form and sends it to the Test Center (PDF sent by email with signature and company stamp);
2. The Test Center agrees with the Applicant on the test plan;
