DOE-STD-3025-99 iii FOREWORD This Department of Energy standard supercedes DOE NE F 3-43 and is approved for use by all DOE components and their contractors. This standard was developed primarily for application in U.S. Department of Energy programs. It contains specific direction for HEPA filter testing performed at DOE-accepted HEPA Filter Test Facilities (FTFs). Beneficial comments (recommendations, additions, deletions) and any pertinent data that may improve this document should be sent to the Office of Nuclear Safety Policy and Standards (EH-31), U.S. Department of Energy, Washington, D.C. 20585, by letter or by using the self-addressed Document Improvement Proposal form (DOE F 1300.3) appearing at the end of this document. DOE technical standards, such as this standard, do not establish requirements. However, all or part of the provisions in a DOE standard can become requirements under the following circumstances: (1) they are explicitly stated to be requirements in a DOE requirements documents; or (2) the organization makes a commitment to meet a standard in a contract or in an implementation plan or program plan required by a DOE requirements document. Throughout this standard, the word "shall" is used to denote actions that must be performed if the objectives of this standard are to be met. If the provisions in this standard are made requirements through one of the two ways discussed above, then the "shall" statements would become requirements. It is not appropriate to consider that "should" statements would automatically be converted to "shall" statements as this action would violate the consensus process used to approve this standard. NOTICE The “Preparing Activity” wishes to establish continuity between this standard (DOE-STD-3025-99) and its direct predecessor, entitled “DOE Filter Test Facilities Quality Program Plan (NE F 3-43)”. The original standard was first issued by DOE as a Nuclear Energy (NE) standard on July 1986. DOE-STD-3025-99 iv INTENTIONALLY BLANK DOE-STD-3025-99 v TABLE OF CONTENTS PARAGRAPH PAGE 1.

GENERAL PROVISIONS Each HEPA filter procured for installation in a DOE nuclear facility shall be submitted for testing at a Filter Test Facility (FTF). The tests are performed in accordance with section 5 of this standard, the customer’s written specifications or procurement documents, and any special written instructions from the customer. Unless otherwise instructed, FTF tests and inspections shall include: C Visual inspection for compliance with purchase order, e.g., type, size, quantity received, shipping damage, and Qualification Certification. C Visual inspection for manufacturing defects and compliance with construction and materials requirements. C Penetration at 100% (all filters) and penetration at 20% (size 3 and higher) of nominal airflow rating. C Airflow resistance at 100% of test airflow. DOE-STD-3025-99 6 C Verification that the filter make and model is approved by DOE. Maximum penetration allowed is 0.03% (0.0003) at an aerosol particle diameter of 0.3 micrometers. If a higher penetration is measured, the filter shall be rejected and the customer notified that the filter does not meet the penetration requirement. When tested with a DOE- approved laser spectrometer test method, the maximum penetration and the aerosol particle size of maximum penetration shall be reported in addition to the penetration at 0.3 micrometers diameter. However, penetration at 0.3 micrometers diameter shall be the only criterion used to judge whether a filter is rejected for excess penetration. Maximum airflow resistance (see Section 5.2.2, Table 1 of DOE-STD-3020-97) is 1.0 inches of water gage (in. H2O) (250 Pa) across the filter pack for size 4 (nominal 500 cfm) through size 6 (nominal 1250 cfm) filters, and 1.3 in.H2O (325 Pa) for filters size 1 (nominal 25 cfm) through size 3 (nominal 125 cfm) and filters size 7 (nominal 1500 cfm) and size 8 (nominal 2000 cfm). The resistance shall be reported to the nearest 0.1 in. H2O (25 Pa). There shall be no waivers from penetration or resistance requirements, nor shall defects in the filter media be repaired at the FTF. It is the responsibility of the purchaser and the manufacturer to determine proper disposition of non-conforming filters. 5. PROCEDURES All FTF operations shall be conducted in accordance with written procedures that address the subjects and inform to this standard. All procedures shall contain specific acceptance criteria. Each FTF shall prepare, maintain, and operate in accordance with detailed procedures which cover, as a minimum, the following functions: C Receiving inspection. C Un-boxing, handling, re-boxing, and storage of filters. C Inspection for defects, damage, and compliance with purchase order specifications. C Verification of compliance with qualifications test requirements, e.g., over- pressure resistance, fire and heated air test, and resistance to rough handling (QPL listing). C Documentation and records keeping. DOE-STD-3025-99 7 C Operating and calibration procedures for each penetration and resistance test device. C Test and inspection reports, including disposition and retention. C Labeling of accepted and rejected filters. C Segregation and disposition of rejected filters.

C Shipping of accepted filters. C Preparation of semiannual reports to DOE. C Training and qualification of personnel. C Surveys or precautions taken for protection of health, safety, and the environment. 6. RECEIPT OF FILTERS 6.1 Receiving Inspection All filter packages shall be inspected upon receipt at the FTF. Damaged cartons or cartons improperly oriented shall be opened immediately and the filters inspected. A description of observed damage shall be recorded in the filter inspection and test report. 6.2 Initial Handling and Storage Filter handlers shall be properly trained to handle filter boxes carefully. Cartons shall be oriented with arrows on the filter cartons pointed "up". Filter cartons shall be stacked not more than three (3) high, and stored in a clean, dry location. Unless otherwise required, storage facilities for HEPA filters shall be equipped with temperature and humidity controls. 6.3 Pre-Test Filter Damage Inspection Prior to testing, each filter shall be visually examined for possible damage, compliance with purchaser’s specifications, and workmanship. Damage to filters noted during the pre-test inspection shall be recorded on the filter inspection and test report. Filters obviously damaged shall not be further tested, but shall be immediately rejected. DOE-STD-3025-99 8 The damage inspection shall, as a minimum, include: verification of general workmanship, filter type, size, gasket installation and material, separators, frame dimension, squareness, face guards, and required labels or markings. Filters shall be inspected for looseness of filter packs, excessive slump or distortion, loose gaskets, breaks or tears, or patching of the filter medium. 7. PENETRATION AND RESISTANCE TESTING 7.1 Testing Requirements and Test Methods Following visual inspection, each filter, completely encapsulated in the test apparatus, shall be tested for penetration at 100% of the nominal air flow rating, and filters rated at 125 cfm (0.059 m3/s) or greater shall also be tested at 20% of the nominal airflow rating. Each filter shall be tested for resistance to airflow at 100% of the nominal airflow rating. Test air flow rates shall be measured in actual cubic feet per minute (acfm), not standard cubic feet per minute. The filter test apparatus shall be equipped with "chucks" which encapsulate the HEPA filter in the test position. Self contained (nipple ended) filters shall not be routinely tested for resistance to airflow. Operating and test procedures shall be prepared for each test device and shall include, as a minimum, the following elements: C Filling the generator reservoir and verification of fluid level. C Daily verification of airflow rates using NIST traceable orifice plates. Flow rates shall be adjusted to within + 2% of the orifice plate calibration value. C Adjustment and verification of critical airflows (and temperatures for thermal test method only). C Calibration of filter test equipment which determines particle size, penetration, and resistance. Calibration of instruments which are used to calibrate the filter test equipment. C Calibration schedules. C Design and use of adapters to permit tests of non-standard filters or special test procedures. C Operating and calibration procedures. C Operation, service, and maintenance of test equipment, including the system exhaust air cleaning device. DOE-STD-3025-99 9 For penetration and resistance testing, two Penetrometer systems have long been

authorized. Both Penetrometer systems operate using "hot" aerosol. They are: C The Q-107 for testing filters with rated airflows of 250 cfm (0.12 m3/s) and above. C The Q-76 for testing filters with rated airflows below 250 cfm (0.12 m3/s). Currently, a laser spectrometer analyzer system, the High Flow Alternative Test System (HFATS), operating with "cold" aerosol, is the method of choice for testing filters with rated airflows of >250 cfm. It is used in conjunction with the Q-107 system. Provisions for qualifying new test methods appear in Appendix 1 to this standard. 7.2 Test Aerosols Test aerosol materials, currently approved by DOE for FTF testing are Di-octyl Phthalate (DOP) and Di-octyl Sebacate (DOS). Provisions for qualifying new test aerosols appear in Appendix 2 to this standard. 8. INSPECTION AND TEST REPORTS, AND LABELING 8.1 Inspection and Test Report for HEPA Filters A report or data sheet (see Appendix 3) shall be prepared for each customer order. The report shall include as a minimum: C Identification of the FTF. C Name of customer. C Customer order number(s). C Date of shipment receipt at FTF. C Date of inspection and test. C Customer’s specification or standard (if applicable). C Filter manufacturer. DOE-STD-3025-99 10 C Filter description (model or designation number). C Nominal airflow rating. C Test flow air temperature. C Ambient relative humidity in room at time of test. C Barometric pressure at time of test. C Name of operating technician and supervisor responsible for test.

ACCURACY AND CONSISTENCY OF FTF MEASUREMENTS Consolidation of DOE filter testing at one FTF makes it necessary that a new metric be developed for measuring accuracy and consistency of FTF measurements. A new method is being developed in coordination with DOE, the FTF, and the Technical Support Group. The modified procedure will be incorporated in this standard through a Change Notice. DOE-STD-3025-99 17 APPENDIX 1- QUALIFICATION OF NEW TEST METHODS AND EQUIPMENT 1.1 SPECIFICATIONS Only test equipment and measurement techniques approved by the DOE shall be used for quality assurance testing of HEPA filters at the FTFs. DOE approval shall be contingent on satisfactory completion of the following specifications. 1.2 PARTICLE SIZE 1.2.1 Particle Size Range The new instrument and/or test technique shall be capable of determining aerosol penetration in the particle diameter ranged from 0.1 micrometers to greater than 0.3 micrometers in discrete measurable particle size ranges no larger than 0.05 Fm. Particle size measurements shall have a precision and accuracy of ±10%. 1.3 RESISTANCE 1.3.1 Measurement Capability The new instrument and/or test technique shall be capable of measuring airflow resistance within an accuracy and precision of ±5% of a filter under test at its nominal airflow rating. 1.3.2 Calibration Pressure and temperature measuring instruments, orifice plates, mass-flow meters and other instruments critical to performance of the proposed test technique shall be calibrated by the use of standards traceable to recognizable NIST standards. 1.4 PENETRATION 1.4.1 Penetration Measurement The test method shall be capable of determining penetration up to 0.03% +0.005% in the particle diameter range from 0.1 Fm to 0.2 Fm. Aerosol dilution will be permitted only after demonstration that the overall test efficiency and reliability have not been adversely affected, nor have the dilution techniques adversely affected particle size or concentration.

The studies must consider the expected exposure pathways (skin absorption, inhalation) and the fate of the inhaled material in terms of material transfer, residence times, critical organs, and results. Toxicity assessments should consider quantities and concentrations of materials and exposure pathways which approximate realistic occupational or accidental exposure. 2.2.1.1 Engineering Design as Alternative to Toxicity Testing. When toxicity testing has not been performed, or toxicity test results are inconclusive, candidate test aerosols can be used in FTFs if compliance with the following requirements has been demonstrated. C Engineering design and construction is adequate to prevent test aerosols from contaminating breathing air in the FTF (aerosol confinement). C Engineering design and construction of exhaust air handling systems is adequate to minimize quantities of test aerosols released to the surrounding environment. C Applicable exposure limits (concentration guidelines) are established as maximum concentrations for breathing air within the FTFs and for exhaust air from exhaust stacks. C Air sampling or monitoring programs are adequate to determine compliance with the above exposure limits. DOE-STD-3025-99 22 2.2.2 Fire and Explosion Safety Proposed test substances including their aerosol forms shall be analyzed and/or tested to determine that their use under normal testing conditions will present no unacceptable risks due to fire or explosion. 2.3 HAZARDOUS, TOXIC AND MIXED WASTE MANAGEMENT HEPA filter test aerosols shall be selected to avoid generation of EPA regulated wastes by contamination of filters during test activities. Substances known to result in generation of Hazardous Wastes regulated by the Resources Conservation and Recovery Act (RCRA), or Toxic

Wastes regulated by the Toxic Substances Control Act (TSCA), shall not be acceptable candidates for HEPA filter test aerosols. 2.4 TEST AEROSOL CHARACTERISTICS 2.4.1 Mandatory Requirements The test agent shall produce an aerosol with the following characteristics as measured by an approved Penetrometer: The aerosol shall have a size distribution and concentration sufficient to permit precise (see A5.4.1) penetration determinations in the size range from 0.1 Fm to >0.3 Fm using an approved aerosol measurement device.
