6、tember 20. 1995 1. Objective The PIA AAD Design & Testing Report Format is regarded as fulfilled when the manufacturer releases the following test report about his product. The test report will be published by the PIA in the “Para NewsBrief“, and on the PIA Internet Web Site so that the public has a
7、ccess to it. With the following report procedure, every manufacturer has their own choice to define the extent and kind of requirements concerning their particular unit. The requirement regarding quality of each product results from the self-defined test requirements. Each manufacturer is free to de
8、cide which of the actual tests and quality control parameters they want to use in the published test report. The self-chosen quality requirements should be documented. The form of the description should follow a general format. In each section, the manufacturer should describe: - the goal of the tes
9、t, e.g. recognizing of the correct activation altitude, checking of - how many units have been utilized to perform the test in question - the test arrangement correct function under elevated temperatures, etc. - what has been measuredtested? - how has it been measuredtested? - what test equipment ha
10、s been utilized? Each test report shall contain references to all sections, even if they are “not recommended”. All sections should be listed even when no data is presented. In this case a statement such as “not applicable”, “not recommended”, “not appropriate”, “not valid”, or “no statement on this
11、 point” should be included. In the event there is no reference to any particular section, the Para NewsBrief Editor will include the missing section with the notation “no statement supplied by the manufacturer” prior to publishing the report. 2.
