International Cleanroom Certification and Test (ICCAT) has a global affiliation network of certified cleanroom teams. For industries concerned with viable particles, ICCAT specializes in Installation, Operational and Performance Qualifications (IQ, OQ, PQ) or in industries not concerned with viable particles; As Built, At Rest and In Operation. Our validation services also include Environmental Monitoring services for the industries concerned with viable bio-contamination, such as viruses, bacteria, molds and yeasts.


With over 37 years of certification and validation experience, we certify your cleanroom for As Built, At Rest, and In Operation services and for industiries concerned with viable bio-contamination particles, Installation, Operational and Performance Qualifications (IQ, OQ, PQ) validation and testing is performed. The qualifications measures compliance for a safe manufacturing environment for all industries utilizing cleanrooms for manufacturing of their products.

ICCAT is a member of ISNetworld, an online company that maintains safety, insurance, quality and regulatory information on contractors and suppliers.

WHAT IS ISO 14644?

ISO 14644 Standards were first formed from the US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones. The need for a single world-wide standard for cleanroom classification and testing was long felt. After ANSI and IEST petitioned to ISO for new standards, the first document of ISO 14644 was published in 1999, ISO 14644-1.[1]Since then many more ISO 14644 standards have been documented and approved world-wide. Two additional standards 14698-1 & 2 Cleanrooms and Associated Controlled Environments — Biocontamination Control General Principles and Methods and Evaluation and Interpretation of Biocontamination Data respectively has also been adopted to assist with suggestions for cleanroom operations concerned with bio-contamination.

ISO 14644 is now composed of:
  • ISO 14644-1: Classification of air cleanliness[3]
  • ISO/DIS 14644-1.2(2014): Classification of air cleanliness by particle concentration[4]
  • ISO 14644-2: Specifications for testing and monitoring to prove continued compliance with ISO 14644-1[3]
  • ISO/DIS 14644-2.2(2014): Monitoring to provide evidence of cleanroom performance related to air cleanliness by particle concentration[5]
  • ISO 14644-3: Test Methods[3]
  • ISO 14644-4: Design, Construction, and Start-up[3]
  • ISO 14644-5: Operations[3]
  • ISO 14644-6: Vocabulary[3]
  • ISO 14644-7: Separative devices (clean air hoods, gloveboxes, isolators and minienvironments[3]
  • ISO 14644-8: Classification of airborne molecular contamination[3]
  • ISO 14644-9: Classification of surface particle cleanliness[3]
  • ISO 14644-10: Classification of Surface Cleanliness by Chemical Concentration
  • ISO 14644-12: Classification of Air Cleanliness by Nanoscale Particle Concentration
