1 SCOPE This Standard covers in-service testing of ASME N509 high-efficiency air treatment systems for nuclear power plants. 1.1 Use of This Standard This Standard provides a basis for the development oftestprograms and does notinclude acceptance criteria except where the results of one test influence the per- formance of other tests. Acceptance criteria shall be developed based on the design/function in accordance with ASME N509. This Standard is arranged so that the user may select those portions (tests) that are relevant to their applica- tion. Tests should be performed in the sequence listed in Table 1. Table 1 also lists the recommended minimum frequency for performing these tests. The user must specify which tests shall be performed, and the accept- ance criteria for those tests, in the test program. 1.2 Limitations of This Standard This Standard covers the in-service (operational) test- ing of installed air treatment systems. This Standard shall be applied in its entirety to systems designed and built to ASME N509 specifications. Sections of this Standard may be used for technical guidance for testing air treatment systems designed to other criteria. ASME AG-1, Section TA covers the acceptance-testing program. 2 REFERENCES The following references supplement this Standard and are part of it to the extent indicated in the text.

5 VISUAL INSPECTION 5.1 Purpose A visual inspection of the air treatment system, as specified by the test program, shall be made in conjunc- tion with each test series to identify visual deficiencies prior to commencing tests. In addition, this inspection may be used to verify that the system design and con- struction are in accordance with ASME N509. 5.2 Summary of Method Visual inspection shall be performed under a combi- nation of background light plus supplementary light that provides adequate illumination of the surface to be inspected. 5.3 Prerequisites Construction, modification, and/or repairs shall be completed to the extent of supporting the test series. 5.4 Apparatus (Equipment) Supplementary light providing adequate illumination of the surface to be inspected is required. 5.5 Procedure Visual inspections shall be conducted in accordance with ASME N511. Whenever “unacceptable” is used, it is intended to mean anydamage or conditionthatwould impair the ability of the item to perform its function.
