2、ar of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon(e)indicates an editonal change since the last revision or reapproval.1 Scope i.1 This guide is intended to provide a common basis in the se
3、lection of test methods that may be required to evaluate and qualify protective coatings(paints)for use in a light-water nuclear power plant,and all the listed items are for Coating Service Level I application.It lists and describes tests to be conducted on all coatings specified for this service.1.
4、2 This guide also lists the specifications and their scopes that describe evaluation tests for these coating systems.1.3 Coating Service Level I pertains to those coating systems whose failure could impair the operation of the engineered safety features that are essential for preventing the possible
5、 consequences of postulated accidents that could cause undue risk to the health and safety of the general public.Coating Service Level I applies principally to the interior surface of the primary containment for both Pressur-ized Water Reactors(PWR)and Boiling Water Reactors(BWR)and to the structure
6、s and equipment contained therein.Coated surfaces include,but are not limited to,carbon steel,stainless steel,galvanized steel,aluminum,and masonry.1.4 Requirements for coatings applied to other areas shall be assigned at the option of the owner or his designated representative.It is intended that t
