These concentrations will lead to large air sample volumes for classification. Sequential sampling procedure may be applied; see Annex D. Concentration limits are not applicable in this region of the table due to very high particle concentration. Sampling and statistical limitations for particle in low concentrations make classification inappropriate. In order to specify this particle size in association with ISO Class 5, the macroparticle descriptor M may be adapted and used in conjunction with at least one other particle size see C.

Workshop: Review a specification and apply what is in the standard to it Who should attend? You need to gain information on ISO because: You are responsible for outside cleanroom performance testing contractors You perform cleanroom evaluations and certify clean space You are responsible for supervising cleanroom testing Course materials Copy of PowerPoint presentation in a course binder Certificate of course attendance with completion of CEUs This part of ISO specifies test methods for designated classification of airborne particulate cleanliness and for characterizing the performance of cleanrooms and clean zones.
Performance tests are specified for two types of cleanrooms and clean zones: those with unidirectional flow and those with non-unidirectional flow, in three possible occupancy states: as-built, at-rest and operational. The test methods recommend test apparatus and test procedures for determining performance parameters. Where the test method is affected by the type of cleanroom or clean zone, alternative procedures are suggested.
For some of the tests, several different methods and apparatus are recommended to accommodate different end-use considerations. Alternative methods not included in this part of ISO may be used if based on agreement between customer and supplier. Alternative methods do not necessarily provide equivalent measurements. This part of ISO is not applicable to the measurement of products or of processes in cleanrooms or separative devices.

In its first major revision since the original release in , ISO was updated and approved as an International Standard in October and published in December The updates to ISO relating to monitoring and reclassification should also be considered in conjunction with this blog. Below shows the illustrative table derived from the formula from ISO The particular rows and columns that are of most interest in the pharmaceutical industry have been shaded.

So you are looking for complying ISO standard for clean room! A clean room is a very important part of every medical manufacturing process. A company also needs a dust-free clean room to conduct tests and accelerate the innovation process before manufacturing begins. What is a Clean room? Numerous organizations have discovered that the unguarded growth of contamination can bring about product damage, yield decrease, and even product recalls. So, nowadays medical companies are protecting themselves from the unsafe impacts of contamination. In a clean room, the unwanted microorganisms are always carried by humans.
Classification in accordance with this standard is specified and accomplished exclusively in terms of concentration of airborne particulates. It also specifies requirements for the monitoring of a cleanroom or clean zone installation to provide evidence of its continued compliance with ISO for the designated classification of airborne particulate cleanliness. These test methods are specified in the document for two different types of cleanrooms and clean zones; unidirectional flow and nonunidirectional flow. This document is intended for purchasers , suppliers , and designers of cleanroom installations. This standard addresses requirements that are basic to the operation of all cleanrooms, regardless of the application. Topics include:  Operational systems that must be in place  Selection and use of appropriate cleanroom garments  Training and monitoring of personnel and activities  Installation and use of equipment  Requirements for materials used in the cleanroom  Maintaining the cleanroom environment in a clean, usable condition conforming to design standards.
