7、urther experience and investigation may show is necessary or desirable. B. The observance of these requirements by a manufacturer is one of the conditions of the continued coverage of the manufacturers product. C. A product which complies with the text of this Outline of Investigation will not neces
8、sarily be judged to comply with the Outline of Investigation if, when examined and tested, it is found to have other features which impair the level of safety contemplated by these requirements. D.
