It
28、 specifies the parameters which apply, with clearly defined conditions, severities, and pass/fail criteria. The tests are intended to be run as an initial design verification to prove any products ability to satisfy the performance standards requirements. A product that has been shown to meet all th
29、e requirements of a performance standard can be declared as complying with the performance standard, but should then be controlled by a quality assurance/quality conformance program. 2 Normative references The following referenced documents are indispensable for the application of this document.
