ASME N511-2007 pdf free download.ln-Service Testing of Nuclear Air Treatment,Heating, Ventilating,and Air-Conditioning Systems.
1.2 Purpose
The purpose of this Standard is to provide requirements for in-service testing, the results of which are used to verify that the nuclear air treatment, heating. ventilating, and air-conditioning systems perform their intended Iunction
1.3 Applicability
This Standard applies to the in-service testing of nuclear air treatment, heating. ventilating, and air-conditioning systems that have been designed, built, and acceptance tested in accordance with ASME AG-I. Sections of thisStandard may be used for technical guidance when testing air treatment, heating. ventilating, and air-conditioning systems designed and built to other standards.
1.4 Use of This Standard
This Standard provides a basis for the development of test programs and does not include acceptance criteria. except where the results of one test influence the per. Iorniance of other tests. Based on the sVstem design and its function(s), the owner shall develop a test program and acceptance criteria.
Nonmandatorv Appendices A through C provide additional information and guidance.
1.5 Definitions
The definitions provided in this section supplement those listed in ASME AG-I, Article AA-1(NJO.
abnormal i,,cident: any event or condition that may adversely affect the function of the nuclear air treatment. heating, ventilating, and air-conditioning systems.
ac*’ptanci’ test: a test made upon completion of labricatirm, installation, repair, or modification of a unit, component, or part to verify to the user or owner that the item meets specified requirements.
adsorbent: a solid having the ability to concentrate other substances on its surface.
adsorbcr a device or vessel containing adsorbent.
adsorbrr bank or filter bank: one or more filters or adsorbers secured in a single mounting frame, or one or more side by side panels containing poured or packed air treatment media, confined within the perimeter of a duct, plenum, or vault cross section, sometimes referred to as a stage.
aerosol: a stable suspension of particles, solid or liquid, in air.
challenge: to expose a filter, adsorber, or other air treatment device to an aerosol or gas of known characteristics, under specified conditions, for the purpose of testing.
challenge aerosol: an aerosol used for in-place leak testing of installed HEPA filter systems.
NOTE: The polydispersed aerosol used for in-place leak testing of systems differs in size from the 0.3 m nionodisperse flOP aerosol used for efficiency testing of individual I (EPA filters by minufacturers, For potential substitutes for DOi reIewnce ASME AC-i, Article TA-2(X).
challenge gas: a gas of known characteristics used for in- place testing of adsorbers.
HEPA filter (high-efficiency particulate air filter): a disposable, extended media, dry type filter enclosed in a rigid casing that exhibits a minimum efficiency of 99.97% when tested with an essentially monodisperse 0.3 urn test aerosol.
in-service test: a test to determine the operational readiness of a system or component.
pressure, maximum operating: the maximum pressure the system components will be subjected to while performing their function, including the allowable pressure during abnormal operating conditions, that will not physically damage the system or component (e.g., sudden closure of dampers or ftgi.ters).
pressure, operating: the pressure that corresponds to the normal design operating mode of the system. This pressure is less than or equal to the maximum operating pressure.
