This is an exceedingly stringent and impracticable interpretation. Of course, engineering changes are not prohibited, which is what seems to be implied. Due diligence can be demonstrated if each change is evaluated by a competent person to *determine* whether re-testing (which can be limited re-testing) is required or not. This is precisely the purpose of keeping the technical file, which should record all such evaluations -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
