Clean Room Design Standards

If you are a manufacturer of non sterile medicinal products you should define your own clean room area standards using national and international standards.

Clean room design standards. Cleanroom classification particle count. Cleanroom testing certification commissioning and qualification. The 4 important air conditioning design considerations for clean room system design are. They should be computed by an hvac cleanroom expert as many aspects must be taken into consideration such as the size of the room the number of people in the room the equipment in the room the processes involved the heat gain etc.

Prepared under ashrae technical committee 9 11 clean spaces ashrae design guide for cleanrooms is the culmination of the years long work of subject experts from around the world. Cleanroom design in select industries. The class defines a minimum cleanliness level not a specific design. As built at rest and operational.

Usually manufacturers will define an airborne particulate concentration standard class such as iso 14644 1 iso 8 at rest outline gowning and a pressure cascade regime defining a. Learn how you can become a part of projects like this. Cleanroom testing for compliance. As stated before cleanrooms are classified by how clean the air is according to the quantity and size of particles per volume of air.

What exactly is cleanroom classification. When people are added to the matrix particulate levels rise still further in the operational cleanroom. Cleanroom requirements and standards provide a direct and easy to understand way of detailing the differences between the eight classes of cleanrooms. Cleanrooms are rated based on the number of particles they can handle.

The basis of cleanroom standards is the micrometer or micron for short µm which is the size of the particles to be filtered. The particles range in size from 1 5 microns µm. Design criteria clean room iso class 6 environment. Terms definitions and units.

Methods for evaluating and measuring cleanrooms and associated controlled environments. They range from an iso class 1 cleanest to an iso class 8 least clean. The above suggested air changes per hour are only a design rule of thumb. Supplying airflow in sufficient volume and cleanliness to support the cleanliness rating of the room.

Iso delineates three cleanroom classification standards. 36 000 sf open bay type cleanroom positive room pressure controlled to 0 05 wc room conditions at 69 f and 40 rh minimum of 120 air changes per hour 33 ceiling hepa coverage unidirectional vertical airflow 12 ceiling height. Introducing air in a manner to prevent stagnant areas where particles could accumulate.
