The typical filter received at the FTF consists of a glass fiber medium. However, there are many classes of HEPA filters using other medium, such as high-strength, metal, and ceramic, which are currently under various stages of testing, development and review by the American Society of Mechanical Engineers (ASME) Committee on Nuclear Air and Gas Treatment or the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE). These classes of filters will be considered for testing at the FTF if the qualification requirements of ASME AG-1, Code on

Nuclear Air and Gas Treatment have been met or the filters have been successfully analyzed for use in an approved site safety analysis. 4.0 GENERAL REQUIREMENTS The FTF shall maintain and implement a DOE-approved Quality Assurance Program, which is qualified by the DOE in accordance with the contract. The FTF shall independently inspect and test HEPA and ULPA filters in accordance with Section 5.0 of this Standard, the purchaser’s written specifications, procurement documents, and any special written instructions from the purchaser. DOE-STD-3025-2022 2 4.1. Qualification of Filters to be Installed in Nuclear Facilities The FTF shall not test any HEPA filter model unless the filter is qualified prior to purchase in accordance with DOE Standard, DOE-STD-3020, Specification for HEPA Filters Used by DOE Contractors. Legacy filters, such as certain encapsulated filters, that are described in DOE-STD-3020 are required to be tested at the FTF but are exempt from qualification requirements. Prototype filters are required to be tested at the FTF, but can be exempt from qualification by an approved site safety analysis. ULPA filters shall be able to meet the requirements of Institute of Environmental Sciences and Technology, IEST-RP-CC007, Testing of Ultralow Penetration (ULPA) Filters, and IEST-RP- CC001, HEPA and ULPA Filters. Qualification requirements for ULPA filter models prior to purchase will be specified in the next revision of DOE-STD-3020. 4.2. Quality Assurance Inspection and Performance Testing of Filters at a DOE- approved FTF Prior to installation in a DOE nuclear facility, HEPA filters are independently inspected and tested at the FTF in accordance with DOE-STD-3020. Filters rated below 20 actual cubic feet per minute (ACFM) airflow that are ULPA filters will be tested at the FTF in accordance with Institute of Environmental Sciences and Technology publications IEST-RP-CC001 and IEST-RP- CC007. Unless otherwise instructed by site purchase order, FTF inspections and tests shall include: • Visual inspection for compliance with purchase order (e.g., type, size, quantity received, and shipping damage). • Visual inspection for manufacturing defects and compliance with construction and materials requirements as shown in DOE-STD-3020 for HEPA filters or purchaser specifications. • Penetration testing at 100% rated airflow for all filters. • Penetration testing at 20% for filters with rated airflow of 125 ACFM (212 m3/hr) and higher. DOE-STD-3025-2022 3 • Airflow resistance testing at 100% of rated airflow. The FTF will notify the site, the Office of Nuclear Safety (AU-30), and the manufacturer within five working days of any filter that fails testing. The test report of the filter that failed testing will be provided with the notification. HEPA Filter General Performance Testing Requirements HEPA filter maximum penetration allowed is 0.03% at an aerosol particle diameter of 0.3 micrometers. If a penetration greater than 0.03% is measured, the filter shall be rejected, and purchaser notified in writing with the test results that indicate the filter does not meet the penetration requirements. The resistance shall be reported to the nearest 0.1 inches water gauge (in wg) or 25 Pascal (Pa). Maximum airflow resistance for HEPA filters is shown in DOE-STD-3020 or as otherwise noted in ASME AG-1 at rated airflow. DOE-STD-3020 contains the following tables related to maximum airflow resistance at rated airflow:

• Table 5-1. Nominal Sizes and Ratings for FC HEPA Filters; • Table 5-3. FK Type 1 Radial Flow HEPA Filters - Nominal Rating; and • Table 5-4. FK Type 2 Axial Flow Circular HEPA Filters - Nominal Rating. ULPA Filter General Performance Testing Requirements ULPA filters rated below 20 ACFM that are to be used as a safety component in DOE nuclear facilities shall be inspected and tested per the purchase order or the latest versions of IEST Standards. If no testing requirements are identified in the purchase order for filters rated below 20 ACFM, the FTF will request that the purchaser provide the test procedures, or the filter will not be tested until a test procedure is specified. The purchaser should ensure that the factory conducts testing with the most penetrating particle size (MPPS). The purchaser should provide the allowable penetration to the FTF as it can vary depending on the ULPA filter model purchased. Allowable penetration specified should be no more than 0.0010% at the rated flow. Particle size for test aerosols for ULPA filters should be specified in the purchase order. The default MPPS for ULPA filters is a 0.1 micrometer diameter. DOE-STD-3025-2022 4 5.0 FILTER TEST FACILITY PROCEDURES All FTF operations shall be conducted in accordance with written procedures that conform to this Standard and its DOE-approved quality assurance program. All FTF procedures shall contain specific acceptance criteria. The FTF procedures shall also cover the following functions: • Receipt inspection. • Un-boxing, handling, re-boxing, and storage of filters. • Inspection for defects, damage, and compliance with purchase order specifications. • Performance of physical measurements as necessary to determine if dimensional requirements, squareness requirements, and pleat curvature requirements are met. • Verifying that the arrow label is attached in the correct air flow direction. • Documentation and records keeping as specified in the FTF contract. • Operations and calibration procedures for each penetration and resistance test device. • Test and inspection reports, including disposition, retention to be available as records to DOE upon request. • Labeling of accepted and rejected filters. • Segregation and disposition of rejected filters. • Shipping of accepted or rejected filters. • Preparation of status reports. • Preparation of monthly and semiannual reports to DOE. • Training and qualification of personnel. 5.1. Receipt of Filters Processes FTF Receipt Inspection Any filter shipment received without a previously transmitted purchase order shall not be processed for testing until the appropriate purchase order is received. All filter packages, crates, and pallets accepted shall be inspected upon receipt at the FTF. Any damage must be noted on the Bill of Lading before signing. The FTF has the option of declining receipt of any packages with excessive damage. Upon acceptance, damaged cartons, and cartons improperly oriented DOE-STD-3025-2022 5 shall be opened immediately and the filters inspected. A description of any observed damage shall be recorded on the filter inspection and test report. The state of the shipping container needs to be verified that it is in compliance with the applicable sections of DOE-STD-3020, followed by further verification that there are no fasteners (e.g., nails, screws, etc.) protruding into the container that could potentially damage filters or place workers at risk of injury while handling

filter packages. Initial Handling and Storage Filter handlers shall be properly trained to handle filter cartons correctly. Cartons shall be oriented with arrows on the filter cartons pointed "up". Filter cartons shall be stacked not more than three (3) high, and pallets shall not be stacked on top of one another, or other material stacked on top of filter pallets. Filters shall be stored in a clean, dry location. Storage facilities for filters shall be equipped with temperature controls to meet storage requirements specified in DOE-STD-3020. Pre-Test Filter Inspection Prior to testing, each filter shall be visually examined for possible damage, compliance with applicable sections of DOE-STD-3020 or purchaser’s specifications, and workmanship. Damage to filters noted during the pre-test inspection shall be recorded on the filter inspection and test report shown in Appendix A, Part 1, HEPA and ULPA Filter Test Report, and Part 2, Visual Inspection Checklist. Damaged filters shall not be tested but shall be immediately reported to the purchaser for disposition. An exception to this requirement is when the only defect is related to labeling on the filter or packaging. The inspection shall include verification of general workmanship, filter type, size, gasket installation and material, separators, frame dimension and material, squareness of rectangular filters, parallelism of media face, face guards (or galvanized mesh), and required labels or markings. Filters inspected with only labeling or marking deficiencies shall be tested and forwarded to the purchaser with an added label identifying the deficiency. Squareness of filters is determined by using the requirements of Section FC in ASME AG-1. Filters shall be inspected for looseness of filter packs, excessive slump or distortion, loose gaskets, breaks or tears, or patching of the filter media. DOE-STD-3025-2022 6 Manufacturer’s labels shall be legible and contain information as specified in ASME AG-1 as well as test data, manufacturer’s test date, and medium area. In addition, the FTF shall verify that any existing air flow label is pointing in the correct direction. 5.2. Penetration and Resistance Testing Considerations Testing Requirements and Test Methods Following visual inspection, each filter, completely encased in the test apparatus, shall be tested for penetration at 100% of the rated airflow, and filters rated at 125 ACFM (212 m3/hr) or greater shall also be tested at 20% of rated airflow. For encapsulated filters, a special housing may be required to ensure the filter is encased within the test apparatus. Each filter, except encapsulated filters, shall be tested for resistance to airflow at 100% of the rated airflow. Test air flow rates shall be measured in ACFM. If approved in writing by the DOE, conversion to standard cubic feet per minute (SCFM) is not required. Test conditions are required to be shown on all test reports. The filter test apparatus shall be equipped with "chucks", which encase the HEPA filter in the test position. Encapsulated filters shall not be routinely tested for resistance to airflow. Operating, calibration, and test procedures shall be prepared for each test device and shall include, as a minimum, the following elements: • Filling of the generator reservoir and verification of fluid level. • Daily verification of airflow rates using National Institute of Standards and Technology

(NIST) traceable orifice plates. Flow rates shall be adjusted such that the inclined manometer reading is within +/- 0.02 in. wg of the orifice plate calibration value. • Adjustment and verification of critical airflows (and temperatures for thermal test method only). • Calibration of filter test equipment, which determine particle size, penetration, and resistance. • Calibration of instruments, which are used to calibrate the filter test equipment. • Equipment maintenance and calibration schedules. • Design and use of adapters to permit tests of non-standard filters or special test procedures. • Operation, service, and maintenance of test equipment, including the system exhaust air cleaning device. DOE-STD-3025-2022 7 For penetration and resistance testing, the following types of Penetrometer Systems are authorized that use approved test aerosols. • As to be determined by the most recent contract use the Q-107 or preferred laser method for testing filters with rated airflows greater than or equal to 250 ACFM (425 m3/hr). • As to be determined by the most recent contract use the Q-76 or preferred laser method for testing filters with rated airflows less than 250 ACFM (425 m3/hr). DOE shall be notified in writing of any proposed modification to the FTF equipment or testing protocols. Modifications shall be approved in advance by DOE. Approved Test Aerosols Test aerosol materials currently approved by DOE for HEPA and ULPA filter penetration testing are di-octyl phthalate (DOP), also known as DEHP, di-octyl sebacate (DOS), also known as DEHS, and poly-alpha olefin (PAO). Polystyrene latex (PSL) spheres with 0.3 micrometer diameter may also be used but only when testing filters made with glass fiber media in accordance with IEST-RP-CC007. Other aerosol materials may be approved for use by DOE after evaluation by the Office of Nuclear Safety. The DOP and DOS aerosols may be generated by a thermal aerosol generator to produce 0.3 micrometer aerosols. Alternatively, a Laskin nozzle can be used to generate and heterodisperse DOP and DOS aerosols and a laser particle counter can be used to measure the amount of maximum penetrating particle sized aerosols for testing filters. Particle size for testing HEPA filters is specified at 0.3 micrometers. Particle size for test aerosols for ULPA filters should be specified in the purchase order as the required particle size can vary based on the ULPA filter purchased. The default MPPS for ULPA filters is a 0.1 micrometer diameter. 5.3. Inspection and Test Reports and Labeling Requirements FTF Inspection and Test Reports for HEPA and ULPA Filters Upon completion of quality assurance inspections and performance tests, the FTF shall provide a written report of test data to the purchaser in accordance with Appendix A. Additional information regarding the serial number and calibration due date of all measuring and test equipment should also be provided upon request. Reasons for rejection of any filters shall be included in the report and the rejected filters shall be specifically identified. The FTF shall DOE-STD-3025-2022 8 provide the purchaser with a written test report, however, the site is responsible for tracking any rejected nonconforming items in accordance with its Quality Assurance program.
