Inspection and Test Report for HEPA Filters

DOE-STD-3025-99

Filter description (model or designation number).

Nominal airflow rating.

Test flow air temperature.

Ambient relative humidity in room at time of test.

Barometric pressure at time of test.

Name of operating technician and supervisor responsible for test.

Serial number of each filter tested.

Resistance (in. wg or Pa) across filter pack at nominal airflow rating.

Penetration at nominal airflow rating.

Penetration at 20% of rated airflow [filters 125 cfm (0.059m3/s) and above].

Remarks: Reason for rejection.

P = penetration

O = other: describe briefly

When tests are conducted with the HFATS, 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.

Penetration results shall be reported to the nearest .01%. 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. For example, a reading

of 0.023% shall be reported as 0.02%; a reading of 0.026% shall be reported as 0.03%.
