6.1.3

Overpressure Resistance. The new, unused filter, when

preconditioned according to ASME AG-1 Code, Section FC, Section

5140, "Resistance to Pressure," shall withstand a pressure differential

of 10 0.2 in. wg (2500 50 Pa) for 60 minutes without visible

evidence of damage. Within 15 minutes of the pressure differential

test, and while still wet, the filter shall meet the penetration

requirement of Section 6.2.2 at 20% of nominal airflow rating (size 4

and larger filters).

Resistance to Fire and Heated Air. The new, unused filter shall

6.1.4

withstand exposure to air heated to 700F 50F (370ʱ28C) for 5

minutes. After exposure to heat, the penetration, when tested at

nominal airflow rating, shall not exceed 3.0%. There shall be no

evidence of sustained burning when subjected to a spot flame at any

point on the filter except the gasket. Labeling or certification (by

Underwriters Laboratories) in accordance with UL-586 shall provide

evidence of satisfactory compliance with applicable requirements for

resistance to fire and heated air.

Resistance to Rough Handling. The filter shall withstand shaking for

6.1.5

15 minutes at 3/4-in. (19 mm) amplitude and 200 cycles per minute

(3.33 Hz) without evidence of filter damage. The test shall be

conducted with the filters boxed, and the pleats and separators

vertical. After the test, the filter shall meet the penetration

requirement of Section 6.2.2 of this standard at 100% (all filters) and

20% (125 cfm [212 m3/hr] and larger) at the nominal airflow rating.

Acceptance Inspection and Testing. Prior to installation at a DOE

6.2.1

site, each HEPA filter shall be tested at a DOE FTF. Acceptance is

contingent upon satisfactory completion of inspections and tests

specified in DOE Standards. Filters will be inspected for physical

damage to the packaging and filter, and for compliance with

specification requirements which can be checked visually. Each filter
