A Infrared Windows manufacturer will raise a valid concern and then quote carefully selected sections of standards to support a certain position. In doing so however, they fail to display any technical knowledge with the consequence that their position falls well short of fully and properly addressing the valid concern that they raised.
QUESTION. Is there a disconnect in the interpretation of IR Windows and standards such as IEEE C37.20.2 Impact test requirements. Since crystal optics have a clear (and seemingly undisputed, even from manufacturers of polymer IR Windows) benefit of visual and infrared inspection in one IR Window, does the IEEE Impact test apply and do these devices derate your ‘gear if they can’t comply? However, the question isn’t actually a bad one to pose, if a response is given which takes account of the technical issues involved and overall objective rather than aimed at supporting a certain position.
