Ensuring that cleanrooms operate correctly is crucial to maintaining a clean and safe environment. Testing is an essential step that must be taken both at the beginning and throughout the lifespan of the cleanroom. It helps to confirm that the air supply is sufficient and of high quality, air movement is adequate within cleanrooms, and the level of particles and microorganisms is within acceptable limits. By conducting these tests, one can ensure that their cleanroom functions optimally and provides the necessary user protection.
Testing a cleanroom requires skill, and the Cleanroom Testing and Certification course is provided to ensure this. The CTCB-I, a non-profit-making board, carries out teaching and certification. It was set up initially by the Scottish Society for Contamination Control (S2C2) as an education and training initiative to help fulfil the objectives of S2C2. The Irish Cleanroom Society joined CTCB-I in 2003, followed by R3Nordic in Scandinavia and, more recently, VCCN in the Netherlands and the CCN in the United Kingdom. The organisation was renamed CTCB-I in 2009 to reflect its increasingly international dimension.
Candidates can register for either of the two levels of certification.
The Professional candidacy is for cleanroom testing professionals who routinely test all aspects of cleanroom testing. At the time of their final exam, they should have at least 2 years of experience. If you apply for and have suitable qualifications, you will be required to:

All candidates will attend a one-day course on practical aspects of filter integrity and air and velocity measurement. The written exams are identical in both qualifications. Professional candidates will have 2 years of experience and show high practical competence.
For Associate candidates, practical aspects will be taught, but no practical examination is expected. Students who have obtained the Associate qualification may convert to a professional certificate once they have a minimum of two years of experience and can pass the practical exam.

The candidate will be required to write up reports on the two tests. Candidates are expected to carry out the above tests competently, and accurately measure the airflow and find filter leaks.
Associate candidates will receive a certificate on passing the written examination. Professional exams will be marked in two parts i.e. practical and theoretical, so that it is possible to pass none, one, or both exams. It is necessary to pass both exams to be certified. It is anticipated that about 80% of the professional candidates will pass both exams in the first attempt. Anyone failing an exam can re-sit it at the next examination. Successful candidates are registered on this site in the Professional or Associate registers.
