Cleanroom qualification

Testo Industrial Services offers you professional support for all GMP measures in the area of cleanroom qualification. We carry out all qualification tests in accordance with Annex 1 of the EU GMP Guide, DIN EN ISO 14644 and VDI 2083.

In addition to cleanroom qualification, our cleanroom solutions also include testing and qualification of safety cabinets, isolators and other clean air systems.

We accompany you from the conception and planning of the qualification phases (DQ, IQ, OQ, PQ), through the implementation of risk management in accordance with the requirements of ICH Q9/ EU GMP guidelines, to the maintenance services and requalification measures of your cleanrooms. We support you with individual measurements or take over the complete project management.

Our service for you:

Validation of the Saveris monitoring system for monitoring temperature and humidity values

Climate measurements

Reproducible climatic conditions are indispensable for the production of sensitive products in cleanrooms. We support you in ensuring constant temperature and humidity values in your clean room:

  • Individual measurements of temperature and relative room humidity
  • Carrying out climate mappings in cleanroom areas
  • Definition of critical monitoring points
  • Commissioning, validation and calibration of monitoring systems
Performing a differential pressure measurement on a HEPA filter in a clean room

Pressure measurements

The protection of cleanroom areas from contamination from less clean areas is ensured by a differential pressure concept with controlled overpressure. By measuring the pressure and the air flow, operational safety can be increased and the quality of the products ensured.
We support you with qualification measurements in your cleanrooms:

  • Proof of the differential pressure cascades
  • Differential pressure measurement on the filter
Determination of the flow velocity of a TA flow with the aid of a vane wheel

Flow measurements

Maintaining defined, cascaded positive pressure chambers generates air flow from areas of higher purity to areas of lower purity. By supplementing pressure measurement with measurement of air flow and flow direction, operational reliability can be increased.
We support you with qualification measurements in your cleanrooms:

  • Determination of the supply air volume flow
  • Calculation of the air exchange rate
  • Flow visualization
  • Determination of the flow velocity of TAV flows

Air purity/filter performance test

Manufacturing rooms represent the production environment and thus have a decisive influence on product quality. Air purity and filter performance must be tested regularly. The results of measuring the airborne particles in the cleanroom in the "at rest" and "in operation" states prove whether the particle count meets the specifications for the defined cleanroom class. The filter leakage test is a metrologically complex part of cleanroom qualification and is carried out in accordance with DIN EN ISO 14644-3. We support you with these tests in your cleanrooms: 

  • Determination of the particulate cleanliness class 
  • Recovery time measurements/recovery tests 
  • Filter leak test on the HEPA filter
