DOE-STD-3025-99

3.16

Penetrometer

A machine for determining test aerosol penetration and airflow resistance of HEPA

filters which incorporates an approved aerosol and aerosol generator, a penetration

meter, manometers for measuring resistance to airflow, a flow meter for determining test

airflow, and a chuck assembly for encapsulating and holding the filter under test.

3.17

Preparing Activity

The DOE organization responsible for issue and interpretation of this standard.

3.18

Standard Orifice Plate

A secondary standard for measuring airflow through the Penetrometer. Orifice plates

shall be calibrated using a National Institute of Standards Technology (NIST) traceable

standard as a primary standard.

3.19

Test Aerosol

The aerosol produced from a substance approved by DOE for testing HEPA filters.

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:

Visual inspection for compliance with purchase order, e.g., type, size, quantity received,

shipping damage, and Qualification Certification.

Visual inspection for manufacturing defects and compliance with construction and

materials requirements.

Penetration at 100% (all filters) and penetration at 20% (size 3 and higher) of nominal

airflow rating.

Airflow resistance at 100% of test airflow.
