Metecno (Thailand) Ltd.
Metecno (Thailand) Limited started as a steel roof profiling
company in 1997 and took over the panel business of Alcan Nikkei
Thai Ltd. on May 1, 2000 and integrated it with the group global
business in cold storages and clean rooms.
Today, the Metecno Group has been operating and
expanding around the globe for over 30 years through sustained effort
has become the largest producer of Polyurethane panels all over
Europe, U.S.A, Latin America, Australia, China and Thailand.
The group is committed to make fresh investment in the
region and enhance panel technology and hence offer superior
customer satisfaction.

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)

*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.

APPENDIX
Clean room basics terms
Clean room:
An enclosed area that's controlled environmentally over atmospheric
contamination, temperature, pressure and, often, humidity.
Air Lock:
A room attached to the Clean room. This room has interlocking doors and its
function is to act as a buffer zone between the clean room and the outside
atmosphere, during the transfer of material or personnel. It helps keep
the clean room pressurized and free from infiltrating dirt.
Air Shower:
An enclosed chamber designed to clean personnel and their garments of
contamination, prior to entering the clean room, by means of high velocity
of air jets.
Garments:
These are garments made of synthetic fabrics such as Nylon, Dacron, and Tyvek
and others. They are lint free and limit contamination from personnel.
HEPA filter:
High Efficiency Particulate Air filter, capable of filtering out 0.3
micron particles or larger with 99.99% efficiency
Laminar Flow:
The flow of air in parallel planes (unidirectional).
Micron:
A unit of measurement equal to one-millionth of a meter: 0.00003937 inches.
Particle Size:
Particle size is the maximum dimension of the particle. Linear measure
used for fibrous particles and diameter used for spherical particles.
Pass Thru:
A small enclosure that mounted through the clean room wall and allows
product to be passed through efficiently. Pass thru's cut down on
personnel traffic, hence reducing contamination.
Sticky Mat:
Located at the clean room or airshower entrance, sticky mats are multiple
layers of treated film with adhesive to clean shoe bottoms and sides before entering
the room.
ULPA filter:
Ultra Low Particulate Air filter, capable of filtering out 0.12 micron
particles or larger. ULPA's operate with 99.9999% efficiency.
