What is the purpose of a clean room? The clean room The purpose of every clean room is to control an environment by limiting the presence of sub-micron particles and modifying inadequate environmental conditions. The level to which the environment is controlled is what separates one clean room from another. For instance, a Class 10 clean room has 10 particles of size 0.5 microns per cubic foot of air, where as a Class 100,000 clean room has 100,000 particles of size 0.5 micron per cubic foot of air. The need for clean rooms The electronic, high-tech, semiconductor, pharmaceutical, aerospace,medical and many other industries depend on clean room technology. As products such as cell phone circuit boards become smaller, the chance of contamination in manufacturing becomes higher. For pharmaceutical companies, clean, safe and contaminant-free products are imperative to manufacturing and distributing a viable product. Personnel: the greatest threat! The largest cause of contamination in a clean room is personnel. The following statistics have been taken from "The Austin Index" to illustrate personnel contamination. Personnel sampled were fully clothed in clean room garments and engaged in one of the following: 1. Standing or sitting with no movement resulted in 100,000 particles/minute 0.3 microns or larger. 2. Sitting or standing, light head, hand and forearm movement resulted in 500,000 particles/minute, 0.3 microns and larger. 3. Sitting or standing, average body and arm movement, toe tapping, resulted in 1,000,000 particles / minute, 0.3 microns and larger. 4. Changing positions, sitting to standing, resulted in 2,500,000 particles/minute, 0.3 microns or larger. 5a. Slow walking (2 mph), 5,000,000 particles/minute, 0.3 microns and larger. 5b. Average walking (3.57 mph), 7,500,000 particles/minute, 0.3 micron and larger. 5c. Fast walking (5 mph) 10,000,000 particles/minute, 0.3 microns and larger 6. Climbing stairs, 10,000,000 particles/minute, 0.3 microns and larger

Cleanliness level is classified under specific conditions. The cleanliness of a clean room is measured by the size and number of dust particles in a given volume of air. The rating or classification by the number of particles in a given volume of air and under specific conditions is called cleanliness level class. Regulations vary from country to country, but in most places, the national rule is established by referring to US Federal standard 209E. Biogical clean rooms (BCR) There are three standards for industrial clean rooms (ICR) Class - ISO 14644 US Federal Standard 209e ISO 8 (Class 100,000) ISO 7 (Class 10,000) ISO 6 (Class 1,000) ISO 5 (Class 100) ISO 4 (Class 10) ISO 3 (Class 1) * ISO 2 and cleaner Japanese Standard JIS B9920 (Class 100,000) (Class 10,000) (Class 1,000) (Class 100) (Class 10) (Class 1)
*ULPA filters required in Class 10 - 1 and cleaner applications. HEPA filters used in all others.
In Japan, JIS B9920 and Federal Standard 209E are generally adopted as the standards for industrial clean rooms. The cleanliness level classes are defined in JIS B9920 by the number of dust and particles with a diameter 0.1 micron meter or larger contained in one cubic meter of air. In Federal Standard 209E, the number of particles of 0.5 micron meter or larger contained in one cubic foot is used. An industrial clean room controls non-biological particles such as airborne dust particles. ICRs are mainly utilized in the production lines for the semiconductor, electronic equipment and precision machine industries.

Biogical clean rooms (BCR) Biological clean rooms control the biological particles in the room. The US National Space Aviation Bureau (NASA) Standard NHB-5340-2 specifies the cleanliness level classes. The number of biological particles floating in a given volume of air in the room (particles/ft3) is counted, irrespective of their size, as well as the number of biological particles falling on a given area of the floor of the room, in a given time period (particles/ft3 x week). However, biological particles may propagate, perish, or behave otherwise depending on environmental conditions other than cleanliness, and hence no clear-cut specification have been established. In Japan, various institutions and organic cleanliness levels corresponding to application and purpose. BCRs respond to the increasing needs of the food processing and distribution industries. A biological clean room controls biological particles such as bacteria and microbes (fungi spores). BCRs are extensively used in fields where a controlled aseptic state is required, such as food related industries, medicine and pharmaceuticals.
