A course entitled Particle counting to ISO 14644 Parts 1& 2 Summary The course is called Particle Counting to ISO 14644: Parts 1 and 2. The course lasts one day. The course is for people who are required to classify cleanrooms according to ISO 14644 Parts 1 & 2, or to supervise the people who carry out the classification. This course concentrates on the correct theoretical use of Discrete Particle Counters (DPCs) and a simulated practical application of the data obtained from DPCs to accurately classify a cleanroom. Candidates are only accepted into the course if they have at least 1 year s practical experience in cleanroom validation, and have some mathematical awareness and familiarity with statistical calculations. On registration, the candidate receives a set of self-study course notes, and an example of an exam paper. Prior to attending the course, the candidates are sent a marking schedule, which clearly identifies how the practical simulation examination is marked and what is expected from them. The candidates must study the course notes, and then attend a one-day lecture course and examination. The 2 part examination consists, firstly, of a number of questions about particle counting, 65% of which must be answered correctly to pass the course. The candidate must then write a validation report for a cleanroom suite using drawings of the suite and previously obtained DPC data as per ISO 14644-1:1999, paragraph 4.4. The overall pass mark is 55% but candidates who achieve a pass mark of 75%, or greater, will be awarded a Merit pass. Successful candidates are entered onto the list of successful candidates that is held on the ICS Internet site. This is linked to the ICEB internet site. This registration applies to the person who passes the exam, and not their company. Certified persons will remain registered for 5 years, after which time they must be re-certified by resitting the examination.
