CALIBRATION

Fume hood calibration procedures

Fume hood has no instrument calibration of its own in most labs. Its performance is controlled through qualification (below) and the system suitability or acceptance checks of each test that uses it.

QUALIFICATION

Instrument qualification (DQ · IQ · OQ · PQ)

  1. 01

    DQ — Design qualification

    Defines hood type, size, face velocity, containment standard, materials and alarm needs.

  2. 02

    IQ — Installation qualification

    Checks installation, duct connections, fan, airflow monitor, services and documents.

  3. 03

    OQ — Operational qualification

    Measures face velocity across the opening, checks alarms and visualises airflow with smoke; containment tested to the site standard.

  4. 04

    PQ — Performance qualification

    Periodic face velocity and containment checks in the real lab setting with normal equipment in place.
