Pharmaceutical Industry Compressed Air & Gas Testing Specifications

In the absence of a specified standard, pharmaceutical manufacturers are recommended to rely on the International Organization for Standardization (ISO) 8573-1:2010 air standards in addition to a regular air testing schedule to maintain the appropriate air purities. The ISO 8573 Purity Class chosen by a manufacturing facility is dependent upon the individual manufacturer’s use of the compressed air and its contact with the pharmaceutical product. The facility should begin by performing a Hazard Analysis, which will help the manufacturer identify potential compressed air hazards, assess the existing control measures, and ultimately determine if extra controls are needed.

Trace Analytics, LLC can test to a wide variety of specifications. Some example specs commonly used in Pharmaceutical Industry are shown below:

  1. All classifications based on data measured in the vicinity of exposed materials/articles during periods of activity.
  2. ISO 14644-1 designations provide uniform particle concentration values for cleanrooms in multiple industries. An ISO 5 particle concentration is equal to Class 100 and approximately equals EU Grade A.
  3. Values represent recommended levels of environmental quality. You may find it appropriate to establish alternate microbiological action levels due to the nature of the operation or method of analysis.
  4. The additional use of settling plates is optional.
  5. Samples from Class 100 (ISO 5) environments should normally yield no microbiological contaminants.
