8、are subject to revision as further experience andinvestigation may show is necessary or desirable.B. The observance of these requirements by a manufacturer is one of the conditions of the continuedcoverage of the manufacturers product.C. A product which complies with the text of this Outline of Inve
9、stigation will not necessarily be judged tocomply with the Outline of Investigation if, when examined and tested, it is found to have other featureswhich impair the level of safety contemplated by these requirements.D. A product that contains features, characteristics, components, materials, or syst
10、ems new or differentfrom those covered by the requirements in this Outline of Investigation, and that involves a risk of fire orof electric shock or injury to persons shall be evaluated using appropriate additional component andend-product requirements to maintain the level of safety as originally a
11、nticipated by the intent of thisOutline of Investigation.
