General Requirements - doe-std-3020-20050008

DOE-STD-3020-2005

4. GENERAL REQUIREMENTS: All HEPA filters specified in the scope of this standard

that are to be used for protection of workers, the public, the environment or that are

necessary to enable other safety related air cleaning equipment to function properly, shall be

purchased and tested according to the general requirements of this Section (Section 4), and

the specific requirements of Sections 5 and 6.

In addition, this standard may be used to purchase other filters that prevent the build up of

radioactive material in and around air cleaning systems which may limit personnel access

during operations and maintenance in DOE nuclear facilities.

4.1

As directed by the Secretary of Energy's June 4, 2001 memorandum, 100 percent

Quality Assurance Testing of HEPA Filters at the DOE Filter Test Facility, prior

to use in DOE facilities, filters meeting the following criteria shall be delivered to the

FTF for additional quality assurance testing.

4.1.1

HEPA filters that are used in confinement ventilation systems in Category 1

and Category 2 nuclear facilities that perform a safety function in accident

situations, or are designated as important to safety (i.e., safety class or safety

significant per DOE-STD-3009-94).

4.1.2

HEPA filters necessary for habitability systems (e.g., filters that protect

workers who must not evacuate in emergency situations because of the

necessity to shutdown or control the situation).

4.1.3

For all other applications where HEPA filters are used in confinement

ventilation systems for radioactive airborne particulate, develop and document

an independent tailored filter QA testing program that achieves a high degree

of fitness for service. The program should include the testing of a sample of

filters at the FTF. The size of the sample to be tested should be large enough

to provide sufficient statistical power and significance to assure the required

level of performance.

4.2

HEPA filters shall be qualified per ASME AG-1 and Section 6.1 of this standard.

The filter media shall comply with ASME AG-1.

4.3

All HEPA filters shall be tested by the manufacturer and in addition, those identified in

Section 4.1 shall be tested by the FTF to the following criteria:

Penetration at 100% of manufacturer rated airflow

Penetration at 20% of manufacturer rated airflow for filters rated at 125

ACFM and greater

Airflow resistance at rated airflow. Maximum acceptable resistance for

selected filter sizes is specified in Table 5.1.
