Refrigerant- 11: challenge gas trichloromonofluoromethane (R-lI).
Refrigerant- 112: challenge gas tetrachlorodifluoromethane (R-112 or R-112A).
test boundary: the physical limit component, system, or device being subjected to a leakage test as defined in specific procedures.
test canister: a specially designed sample holder containing sufficient adsorbent for specific laboratory tests that can be removed from an adsorber bank, without disturbing the remainder of the adsorber, to provide representative samples for laboratory testing. A full- sized Type II adsorber tray may be removed and used to obtain material for specific laboratory tests provided that an in-place leak test is performed after replacement.
test program: a schedule that specifies tests and the sequence of tests to be made for the evaluation of a total air- or gas-cleaning system.
4 GENERAL
This Standard delineates the requirements for in-service testing of nuclear air-cleaning systems. Acceptance testing is covered in ASME AG-I. A list of the required in-service tests and the minimum performance frequency of these tests are shown in Table 1.
4.1 Test Procedure
Procedures shall be prepared for each required test, based upon the requirements of this Standard.
4.2 Personnel
Only persons who have demonstrated the competence to satisfactorily perform the specific tests in question as evidenced by experience and training shall perform tests. Personnel shall be certified in accordance with ASME NQA-I or ANS 3.1 and with the owner’s design specifications and quality assurance program.
4.3 Instrumentation: Permanent
Permanent instrumentation used in the performance of tests specified in this Standard shall meet the accuracy requirements specified in Table 2 and shall be calibrated in accordance with the owner’s design specifications and quality assurance program.
4.4 InstrumentatIon: Portable
Portable instrumentation used in the performance of the tests specified in this Standard shall meet the accuracy requirements specified in Table 2 and shall be calibrated in accordance with the owner’s design specifications and quality a&surance program.
5.3 Prerequisites
Construction,modification, and/ or repairs shall becompleted to the extent of supporting the test series.5.4 Apparatus (Equipment)
Supplementary light providing adequate illuminationof the surface to be inspected is required.
5.5 Procedure
Visual inspections shall be conducted in accordancewith ASME N511. Whenever “unacceptable” is used, itis intended to mean any damage or condition that wouldimpair the ability of the item to perform its function.5.6 Acceptance Criteria
Inspection results are acceptable when there are noindications of improper installation, physical damage,structural distress,or degradation that would impairthe ability of the system to perform its intended function.5.7 Report
A written report shall be prepared in accordance withsection 14.Items identified as unacceptable should befurther documented in the comment section of the testreport to assist the owner in preparation of correctiveaction.
6 DUCT AND HOuSING LEAK TEST
6.1 Purpose
These tests are used to verify the leak tightness of thehousings and ducts.
