ISO Parts 1 and 2 Introduction Cleanrooms are highly controlled environments, defined by This article reviews the key changes to the air quality, and where certain physical and microbiological International Organization for requirements need to be met. Air quality is achieved through Standardization ISO standards document a combination of airborne particulate control, such as through ISO Parts 1 and 2, in relation to high efficiency particulate air filters; high fresh air rates air cleanroom classification.

For example, standards began to be issued. Part 2, which has Manufacturing Practice — Medicinal Products for Human and also been subject to a recent revision, specifies requirements Veterinary Use Annex 1 in ISO standards for periodic testing of a cleanroom or clean zone to prove its developed because there was a recognised need for a continued compliance with ISO for the designated single internationally accepted standard for cleanroom classification of airborne particulate cleanliness4.

For reference, the full set of ISO parts is listed below. Classification of air This determined the method by which a room cleanliness should be classified, which is by the maximum allowable particles within a fixed volume of air.

Specifications for testing of three occupancy states.

Design, construction and equipment or personnel within the facility. Operations connected, all the equipment is installed and operating to an agreed manner, but no personnel are present.

Classification of air procedure. Classification of surface For continuous monitoring, EU GMP inspectors will expect cleanliness by particle concentration both cut-off particle sizes to continue to be monitored.

Classification of surface classification and batch-specific monitoring will fit together cleanliness by chemical concentration might be clarified in the forthcoming update to EU GMP Annex 1.

Cleaning of surfaces to 0. Assessment of suitability for use of equipment by airborne particle concentration Hopefully, a regulatory interpretation will be produced to clarify matters. Parts of the standard have been adopted by GMP systems, such as the Determining the number of particle count locations reference to ISO classes in the FDA Guidance on Aseptic A significant change with the standard is the method for Processing5 and the requirement to use the standard to selecting the number and position of particle counter classify cleanrooms in Annex 1 of EU GMP6.

Not all of the parts locations within a cleanroom.

The approach was that the of the standard are applicable to GMP environments, for user calculated the surface area of the cleanroom in square example, Part 12 is intended for the nanotechnology industry.

From this, the square root was taken and the number generated provided the number of particle counter locations.

The more substantial changes relate to Part 1. As part of the With the revision, the method is based on a look-up change process, the title of the second part of the standard table.

These numbers This main part of the article considers the key changes, are based on a statistical method called hypergeometric beginning with Part 1. This is very different to the square root approach, which was based on binomial distribution.

Without Particle sizes going into statistical detail, the former approach assumed Cleanroom users can elect to look at one or more particle that in each location a particle counter was placed, the sizes. In only will continue to look for particles equal to or greater than contrast, the revised approach is based on particles not 0.

The new approach allows each and equal to or greater than 5. This location to be treated independently. Here the For the user, the approach is simpler because no standard indicates that more than one particle size can be calculations are required. In addition, for rooms with less than used, provided the next particle size selected is 1. With There is an issue with Grade A environments, for particles the assigned numbers, there is an in-built confidence interval equal to or greater than 5.

This means that when a cleanroom is monitored, there within the standard. However, the In general, the new approach leads to an increase in standard retains the option for the 5.

This is set out using the formula published in the number of locations was With the revised version, it has standard.

This part specifies test methods for designated classification of airborne particulate cleanliness and for characterizing the performance of cleanrooms and clean zones.

BS EN ISO 14644-6:2007

These test methods are specified in the document for two different types of cleanrooms and clean zones; unidirectional flow and nonunidirectional flow. The most important objectives of this highly referenced document are to provide an internationally common basis of measurement and evaluation of cleanrooms and, at the same time, not to prevent the introduction of new technologies.

This part specifies requirements for the design and construction of cleanroom and clean air devices, as well as requirements for start-up and qualification, but does not prescribe specific technological nor contractual means to meet the requirements. This document is intended for purchasers , suppliers , and designers of cleanroom installations.

ISO provides the basic requirements for operating and maintaining cleanrooms and associated controlled environments. This standard addresses requirements that are basic to the operation of all cleanrooms, regardless of the application.

Topics include: This part was published as an International Standard in This part is an important document for any contamination control professional. This part of ISO specifies the minimum requirements for the design, construction, installation, testing and approval of separative devices in those respects where they differ from cleanrooms as described in Parts 4 and 5.

Separative devices range from open to closed systems. This part of ISO covers the classification of airborne molecular contamination AMC in cleanrooms and associated controlled environments, in terms of airborne concentrations of specific chemical substances individual, group or category and provides a protocol to include test methods , analysis and time-weighted factors within the specification for classification.
