The housing shall be adequately reinforced to withstand a negative or positive pressure of 10 inches water gage. The housing shall be a fluid seal design which incorporates a knife edge that mates into the fluid filled perimeter channel on the face of the filt er. Access to the filter shall be on the side of the housing. There shall be a safety feature where the filter locking arm and access door shall interface in such a manner that minimizes the possibility of the door being closed until the filters are correctly seated in the housing. Prior to leaving the factory, each knife edge shall be checked with an alignment gage to insure proper alignment with the filter. The filter sealing mechanism shall be replaceable and shall be operated through the change-out bag by a locking handle. The mechanism shall exert equal force at the top and bottom edge of the filter when engaging or disengaging the filter from the knife edge. All pressure retaining weld joints and seams shall be continuously welded with no pores allowed. Joints and seams requiring only intermittent welds, such as reinforcement members, shall not be continuously welded. As a minimum, joints and se ams shall be wire brushed and/or buffed to remove heat discoloration, burrs and sharp edges. All weld joints and seams that are a portion of any gasket sealing surface shall be ground smooth and flush with the adjacent base metal. All welding proce dures, welders and welder operators shall be qualified in accordance with ASME Boiler and Pressure Vessel Code, Section IX. All production welds shall be visually inspected per sections 5 and 6 of ANSI/AWS D9.1-1990, Specifications for Welding Sheet Meta l. All hardware on the housing and all mechanical components of the filter sealing mechanism shall be 300 series stainless steel, except for the cast aluminum access door knobs. The filter housing shall be manufactured under a quality assura nce program that meets the requirements of ASME NQA-1, Quality Assurance Program Requirements for Nuclear Facilities, The housing shall be tested for filter fit, operation of the filter clamping mechanism, sealing surface alignment and leak tightness bef ore leaving the factory. Both the filter sealing surface and the complete assembly pressure boundary shall be leak tested by the Pressure Decay Method, in accordance with ASME N510-1995 Reaffirmed, Testing of Air Cleaning Systems, paragraphs 6 and 7 . Pressure readings are recorded once a minute for 5 minutes. There shall be a maximum leak rate of 0.0005 CFM per cubic foot of housing volume at 10 inches water gage.
