NOTE: Review ASME NQA-1 and include or exclude
requirements as necessary. ASME NQA-1 is used for
safety class filtration systems that perform a
fail-safe function, typically for containment of
highly toxic materials.
**************************************************************************
The filtration units and stand-alone isolation dampers shall be
stated in ASME NQA-1.
3.4
STRUCTURAL DESIGN AND SEISMIC QUALIFICATION
**************************************************************************
NOTE: Seismic qualification is required for
filtration systems that perform a safety function
during and after a seismic event. Manufacturer's
standard equipment is normally considered qualified
for the requirements specified below. Review ASME
AG 1, Section AA-4000, and provide specific
additional requirements for the design application.
**************************************************************************
The filtration system, components, and accessories shall be structurally
designed and tested with appropriate documentation and certification as
required by ASME AG 1 Section AA. The service condition of the filtration
system shall meet level [A] [B] [C] [D] service limits with the design
loads indicated. The structural design of the filtration system,
components, and accessories shall be verified by analysis, testing, or a
combination of analysis and testing. The filtration system shall be
subjected to [5] [_____] operating based earthquakes (OBE) and one safe
shutdown earthquake (SSE) as indicated by the required response spectrum.
Each OBE and SSE shall have a minimum test duration of [30] [_____]
seconds. The filtration system, components, and accessories shall meet the
seismic protection requirements specified in Section 13080 SEISMIC
PROTECTION FOR MISCELLANEOUS EQUIPMENT.
3.5
ACCEPTANCE TESTS
All acceptance tests shall be in accordance with the procedures in ASME
N-510-1 and as required by MIL-PRF-32016. Proposed test schedules for
adjusting and balancing, housing leak and pressure, air-aerosol mixing
uniformity, damper operation and leakage, system bypass, and performance
tests of systems, shall be provided at least 2 weeks prior to the start of
related testing.
3.5.1
Visual Inspection
Visual inspection shall be performed in accordance with ASME N-510-1.
3.5.2
Housing Leak and Pressure Test
**************************************************************************
NOTE: Use housing leakage rate of 0.20 percent of
housing volume for all-welded man-entry steel
housings and 0.05 percent for small single-filter
housings.
