HEPA Filter Integrity Test (PAO/DOP)

HEPA Filter Integrity Testing. The HEPA filter integrity test is typically performed on cleanroom supply air HEPA filters using a photometer to scan the filter surface for pinhole leaks that could allow the transmission of contaminant particles that would be unacceptable in a critical application.

Air Change Rate Test

Air changes per hour abbreviated ACPH or ACH, or air change rate is a measure of the air volume added to or removed from a space (normally a room or house) divided by the volume of the space. Vol = Space volume L × W × H, in cubic feet if using Imperial units, or cubic meters if using SI.

Air Flow Visualization Test

Air flow visualization studies are intended to demonstrate visual evidence of air flow direction. The test can also be used to demonstrate the effects on airflow caused by equipment”. The predominant sources of contaminants within a clean room are people and machinery.

Airborne Particle Test

Airborne Particulate Testing. Part of the maintenance and verification of air quality for high caliber medical operations includes routine measurement of airborne particulates in surgical suites, as well as other high-risk hospital areas.

Clean Room Recovery Test

SO 14644-3:2005 gives two recovery tests to determine a cleanroom’s ability to recover quickly from a high concentration of particles, namely, the recovery time and recovery rate. … If the recovery time is set at 15 -20 minutes, this test is similar to that specified by the EU GGMP for a Grade B cleanroom.

Temperature & Humidity Test

It involves setting test chamber conditions to an internal temperature of 85 degrees Celsius and a relative humidity index of 85 percent. This hot, humid environment can be held for as long as 1,000 hours, which many engineering evaluation specifications set out.

Room Differential Pressure Test

In most large-scale FDA-regulated pharmaceutical manufacturing operations, it is required that the product be manufactured in a clean room classified between Class 100 and Class 100,000. In an operation where medical tubing is being extruded, the classification would likely be Class 100,000. In a process where inject-able drugs are being manufactured, the classification would most likely be Class 100 or Class 1000.

Light Intensity Test (Lux)

The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square meter. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.

Sound Level Test

sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level(SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound.
