SCOPE

1.1

Introduction

DOE Order 5700.6C requires that all DOE contractor programs be conducted under

established quality assurance programs. Basic requirements for DOE quality assurance

activities appear in "Quality Assurance Program Requirements for Nuclear Facilities"

ANSI/ASME NQA-1 as specifically applied to DOE Filter Test Facilities (FTF) and their

operation.

1.2.

Definitions

1.2.1

Acceptance Test. Inspection and testing of a nuclear grade filter to verify

certain characteristics or properties which determine acceptance or rejection of

that filter.

1.2.2

Airflow Resistance. An index of the energy required to maintain airflow

through a filter. Airflow resistance is measured in terms of the air pressure

difference (pressure drop) across a filter at a specified flow rate (e.g. see section

5.2.2, Table-1, Standard DOE-STD-3020-97).

Note: The initial airflow resistance of a new filter serves as an index of the

filter' potential loading capacity.

Filter Test Facility (FTF). A facility accepted by the DOE specifically to

1.2.3.

conduct quality assurance inspections and tests of HEPA filters.

1.2.4

High Efficiency Particulate Air (HEPA) Filter. A throwaway, extended-media,

dry type filter with a rigid casing enclosing the full depth of the pleats. Aerosol

collection efficiency of the filter shall be at least 99.97% for 0.3 micrometer

diameter particles. The maximum airflow resistance shall be as specified in

Section 5.2.2, Table 1 of DOE Standard 3020-97.

1.2.5

Penetration. The downstream test aerosol concentration, expressed as a

percentage of the upstream test aerosol concentration.
