A final report is created and marks the end of the certification phase.įigure 2: The accumulator table at the exit of the steriliser tunnel Qualification This table provides the number of sampling locations related to the area of each cleanroom or clean zone to be classified, and provides at least 95% confidence that at least 90 % of the cleanroom or clean zone area does not exceed the class limits.Ĥ.

Derive the minimum number of sampling locations, NL, from ISO 14644-1 Table A.1. It may be more difficult to determine the locations of the sample points due to the unusual shape of the room.Repeat the steps used for the Grade A area.Sample point placement for the Grade B area: It is recommended to have both sets of data, as the FDA requires ISO14644-1, and the EU requires Annex 1 data points (although the EU data would suffice for the FDA).ģ. PASS/FAIL criteria are calculated for ISO and EU GMP Annex 1.This table provides the number of sampling locations related to the area of each cleanroom or clean zone to be classified, and provides at least 95 % confidence that at least 90 % of the cleanroom or clean zone area does not exceed class limits. Samples are taken in a grid pattern at the identified locations.The sample points must all be equidistant and at work height, irrespective of the activity at the location of their placement.Sample point placement for the Grade A (ISO5) area: Find the number of required sample locations.Ģ. Find the number of required sample locations. The number of sample points is based on a statistical function of the area: However, using the example of a classic filling machine (Grade A/ISO 5) within a Grade B (ISO 7) background area, the basic rules of testing can be demonstrated.ġ. There are many different resources to prove ISO compliance and this article will not cover these in depth.

The interactive software of the Lasair III Aerosol Particle Counter can even step the user through the certification process. Particle Measuring Systems’ products, including the Airnet II and IsoAir 310P Aerosol Particle Sensors, comply with new ISO standards set in 2015. This provides a universal standard to show that a cleanroom level has been established. The international standard means that a cleanroom tested to meet compliance for ISO 5 standards will meet that standard independent of geography and regulatory aspects (i.e. That is, irrespective of the final use of the room, only the design and implementation of the filtration system are considered. The specifics of the assessment may vary slightly for FDA or EU GMP regulations, but the underlying methodology is standard.Ĭertification demonstrates that the entire area meets a specific ISO classification by particle concentration. The number of sample points and their location is determined by risk assessment, and the qualification and certification processes.įigure 1: A classic filling machine (Grade A/ISO 5) within a Grade B (ISO 7) background area CertificationĪs mentioned above, cleanroom certification is based on ISO14644-1, “Classification of air cleanliness by particle concentration” standards. Monitoring: The ongoing sampling of the cleanroom on a frequency relative to the degree of control required to prove management over risk to the finished product. Particle counts are measured in both operational and at-rest states however, the operational data is the most valid. Qualification follows grid methodology testing methods. Qualification: The process of analysing risk assessment for the activities in the room. This is done irrespective of the activities performed in it. The only standard recognised worldwide is ISO14644-1, “Classification of air cleanliness by particle concentration”, which defines how a cleanroom performs and its ability to show uniformity across the entire space. Each category requires a different approach.Ĭertification: Measuring a cleanroom to a standard.

Particle counting in pharma applications can be clearly segregated into three categories: certification, qualification and monitoring. The goal of this article is to identify the considerations, establish the most suitable location, and build a scientific rationale for that decision. The answer is not always straightforward and several guidance documents offer advice on what processes need to be monitored, as well as suitable distances from the process. As environmental system designers, we are often asked where to place sample points for particle monitoring, whether it be performed in a pharmaceutical cleanroom or clean device (RABS, isolator, etc.).
