ISO 8573-7 Micro Testing
Two blinds are taken, one before the point of use and one after. Air is aspirated at a fixed speed for a variable time through a cover with small holes. Other analyses are available upon request. You may find it appropriate to establish alternate microbiological action levels due to the nature of the operation or method of analysis.
There 88573-7 no name in the ISO standard for this control plate, however, there is a description as follows: Most plates are sent with sterile bags to send back to the testing lab. Benchmarking Good Manufacturing Practices.
When sampling media is placed on the clips for testing, all efforts should be made to avoid secondary contamination. The purpose is to certify the absence of microorganisms in 1.
ISO is an available standard addressing compressed air quality. Additional information is noted on shape and morphology upon Gram staining. The level of viable microbiological contaminants in the compressed air shall not be detectable using the method described in clause 7.

Breathing Air Distributors Manufacturing Microbial. Feel free to place the lid face down inside iao sterile bag provided, making sure gloves are iiso. Individual settle plates may be exposed for less than 4 hours. It is imperative when choosing the piece of equipment for testing that the technician and monitoring supervisor read the original equipment manufacturer OEM manual to establish what the limits and restrictions are for that product.
The culture plates are contaminated before the use. However, compressed air or process air is frequently overlooked. The only analysis required by ISO is colony forming unit enumeration.
Microbial Testing and Compressed Air Standard ISO 8573-7
Trace Analytics, LLC is an A2LA Accredited Laboratory specializing in compressed gas analysis for the breathing isi, manufacturing, and medical gas industries worldwide. It consists of nine parts that address purity classes, specifications, and procedures.
Specifications do exist for the required blind samples. Values represent recommended levels of environmental quality. The resulted flow of air is directed on to the agar surface of the contact plate Petri dish placed inside the sampler, under the cover with holes.
Afterwards, open the contact plate or petri dish for sampling, the lid should always be placed down, as to not catch any floating microbial vectors like dust inside the lid.
Using Izo sampling and analytical methods, their laboratory tests for particles 0. The blind is taken with the same movements as a compressed air sample, but no air is to enter the funnel head or impact the agarose. When using impact samplers, various sampling heads exist to disperse the air onto the recipient agar plate.
The International Organization for Standardization ISO publishes world-class standards for products, services and systems, to isl quality, safety and efficiency 1. It contains both informative and normative procedures but lacks any tested compressed air microbial specifications regarding colony enumeration limits for microbial plate counts.

It should 85737- noted however, that these samples, while informative, are a snap shot of the level of control in the facilities compressed air system.
Microbial – Compressed Air Testing – Trace Analytics
For simplicity reasons this article will focus on the use of a Pinocchio Super II sampler. One of a series of standards aimed at harmonizing air contamination measurements, it provides a means of sampling, incubating and determining the number of microbiological particles.
The first action is to always wear the minimum appropriate personal protective equipment, PPE Table 3: Most oso air samplers are made to use a sterile tube to sample the outlet air into the inlet port of the unit for analysis.
Bacterial 85773-7 can be resistant to U. Microbial Contamination of Compressed Air Compressed air systems can harbor the nutrients required for microbes to grow; namely water, oil, and warm temperatures. The first type of control plates is called blinds, these blinds before and after are to confirm that no outside or unwanted contamination from external variables sampling technicians and the environment have entered the air sampler or agarose surface. For instance, if the air sample was contaminated with Gram positive cocci bacteria, there is no need to test for Listeria since Listeria is a Gram positive, non-spore forming rod.
Many accreditation bodies iao aid in the understanding of microbial limits and specifications, critical to specific industry needs.
