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

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

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 visualisation 
  • Determination of the flow velocity of TAV flows

Microbiological monitoring

In addition to particle classification measurements, we also carry out microbiological sampling. We take over the complete handling of the monitoring measures from planning to the final report. The limit values for this are defined in the EU GMP guidelines Annex 1. Our services in the field of microbiological monitoring: 

  • Classification measurement (microbiological) 
  • Testing of air (active air sampling or sedimentation) 
  • Testing of surfaces (direct sampling/swab test) 
  • Testing of personnel (in sterile areas) 
  • Determination of sampling points, frequencies and action limits 
  • Sampling 
  • Analysis in a GMP-certified laboratory 
  • Total germ count determination 
  • Identification of germs (to genus or species) 
  • Advice on OOS and OOT results 

Your advantage: Our expertise

  • Expertise: Consulting, measurements, project management - our industry-experienced team supports you precisely & in line with your needs
  • Technology: The use of our measuring equipment with more than 4,500 references ensures reliable measurement and test results
