challenge gas: a gas of known characteristics used for in- place testing of adsorbers. HEPA filter: a high-efficiency particulate air (HEPA) filter. This is a throwaway, extended-medium dry-type filter with a rigid casing enclosing the full depth of the pleats. The filter shall exhibit a minimum efficiency of 99.97% when tested with an aerosol of 0.3 μm diameter test aerosol particles. in-service test: a test to determine the operational readi- ness of a system or component. preconditioning: the modification, manipulation, or adjustment of a component performed just prior to or during an in-service tests that could affect the results of the in-service test. This may include activities such as cycling, cleaning, lubricating, agitating, orotherspecific maintenance or operational activities performed prior to or during in-service testing that could affect the ability to determine componentdegradation. This excludes normal scheduled routine maintenance to keep optimum compo- nent performance. pressure, maximum operating: the maximum pressure the system components will be subjected to during opera- tions. The allowable pressure during abnormal operating conditions that will not physically damage the system or component (e.g., sudden closure ofdampers or registers) is the maximum operating pressure. pressure, operating: the pressure that corresponds to the normal design operating mode of the system. This pres- sure is less than or equal to the maximum operating pres- sure. pressure, structural capability: the pressure, including transients, that verifies the component or system can be safely operated without permanent distortion.

3.1.4 Specific Instrument Accuracy Requirements ð22Þ Vibration Instrument. Vibration instrument accuracy shall be at least ±10%. The minimum frequency response range of the vibration-measuring instrument shall be approximately one-third of the minimum shaft speed. The maximum frequency response range shall be at least the blade pass frequency at maximum design speed or the highest bearing fault frequency (whichever is highest). For rotating components, the maximum frequency response range shall be at least 2 times the rotational shaft speed of the component being measured. For reciprocating components, the maximum frequency response range shall be at least 2 times the speed of the rotating element, times the number of unique planes occupied by a piston throw. Challenge-Aerosol-Measuring Instrument. The challenge-aerosol-measuring instrument shall be verified to have a linear range of at least 10 5 times the minimum detectable quantity of the instrument. Challenge-Gas-Measuring Instrument. The challenge-gas-measuring instrument shall be verified to be capable of distinguishing challenge gas from back- ground and measuring challenge gas over a linear range ofatleast105 times the minimum detectable quan- tity of the instrument.
3.3.2 System Operating Conditions. Operating condi- tions required for in-service testing shall be determined for each system. 3.3.3 Procedure Requirements. The owner shall be responsible for the development and implementation of written test procedures that meet the requirements of this Standard. Each section on equipment testing consists of common (section 4) and in-service (section 5) test requirements and acceptance criteria that apply to each of the systems. The owner shall document which requirements are applicable (see Mandatory Appendices I through IV for development guidance). 3.3.4 ð22Þ In-Service Tests. In-service tests shall be conducted at intervals not to exceed those specified in section 5 or the owner’s test program, whichever is mostlimiting.In-servicetestintervalsaremaximuminter- vals allowed by this Standard and should not be used as defaultintervals in the absence ofsystem-specific evalua- tions. For in-service tests other than regular interval testing, see para. 3.2 or section 7. Specific system test intervals should be determined upon the basis of system design use. Frequencies for in-service test inter- vals are defined in Table 3.3.4-1.
