2. A cleanroom is characterized by ISO14644-1
as a room in which the concentration of
airborne particles is controlled, and which is
built and utilized in a way to limit the
presentation, generation, and maintenance of
particles inside the room and in which other
pertinent parameters, for example temperature,
humidity, and pressure, are controlled as
essential.
3. First, impurities should not be brought into the
controlled environment from an external
perspective
Second, the apparatus or equipment inside the
controlled climate should not produce or in
any case offer ascent to pollutants (for
example because of contact, chemical
responses, or biological processes).
4. Third, contaminants should not be
allowed to collect in the controlled
climate.
Fourth, existing pollutants should be
eliminated out furthest degree
conceivable, and as quickly as possible.
5. Four essential components characterize a
controlled environment:
CLEANROOM DESIGN – Materials of
development and completions are important in
building up cleanliness levels and are
significant in limiting the interior generation
of pollutants from the surfaces.
6. THE HVAC SYSTEM – The trustworthiness of the cleanroom
environment is made by the pressure differential compared and
local areas through heating, ventilation and air-conditioning system.
The HVAC system necessities include:
Providing airflow in adequate volume and cleanliness to help the
cleanliness rating of the room.
Introducing air in a way with prevent stagnant areas where
particles could gather.
Separating the outside and re-circulated air across high efficiency
particulate air (HEPA) filters.
Molding the air to meet the cleanroom temperature and humidity
necessities.
7. INTERACTION TECHNOLOGY - Interaction technology
includes two components:
The development of materials into the area and the development
of people and
The maintenance and cleaning.
Regulatory instructions, systems and activities are important to be
made about the coordination’s, operation strategies, maintenance
and cleaning.
8. MONITORING SYSTEMS
Monitoring systems include methods for
demonstrating that the cleanroom is working
appropriately. The factors checked are the pressure
differential between the external environment and the
cleanroom, temperature, humidity and, now and
again, noise and vibrations. Control information
ought to be recorded on a normal basis.
