Hospital cleanroom is one of the auxiliary measures to control the hospital infection. In
1961, Sir John Charnley (1911-1982) known as “Father of Hip Arthroplasty” in the
British Wrightington Hospital pioneered to, by cleaning the air method, improve the
operating room environment; so that reduce surgical infection. However, the literature
on relationship between air environment and surgical infection rate that had the clinical
significance of medical statistics and was widely cited was published by LidewellOM
et al. in 1987, the title of such literature is of “Multiple Studies on Ultra Clean Air and
Antibiotics Used to Prevent Postoperative Infection in 8052 Cases of Joint
Replacement Surgery”; such study recognized, to a certain extent, the role of ultra
clean air.
Internationally, for the role of the hospital cleanroom and associated controlled
environment in reducing the rate of infection, the medical field and engineering
personnel in the cleanroom and associated controlled environment had their own
opinions. The medical field has long been skeptical about the effectiveness of clean
operating room. In recent year, the international medical field proposed more specific
doubts on the laminar flow clean operating room based on statistical analysis on a
large number of clinical case practice. The introduction of the Russian Federation
Standard GOSTR 52539-2006 General Requirements for Air Cleanliness in Hospital
prepared by Russian Association of Micro-Contamination Control Engineers clearly
states that the cleanroom ventilation, air conditioning system and equipment can’t
replace the traditional hospital bacterial control measures, but can only supplement it.
Human’s cognition on medical infection is still in the process of exploration. In the air
attached to the dust of microorganisms (In the relevant information at home and abroad,
the literature has not been found on the exact relationship between the number of dust
and microorganisms. Obviously, animals and plants are more likely to scatter off the
fine dust containing microorganisms, such as pollen, body debris, etc.) have been
recognized at home and abroad one of the objects of prevention; while purifying the
air in the medical space has become one of the measures to prevent the medical
China’s national serial standards of GB/T 25915 Cleanrooms and Associated
Controlled Environment equivalently adopting ISO 14644 internals serial standards
drew lessons on the international counterparts’ systematic concepts in each links such
as test, design, construction, start operation, etc. To give full play to the role of the
hospital cleanroom, and meet the use requirements, every detail in the operation can’t
be ignored.
The energy consumption for the air conditioning system and ventilation in the hospital
cleanroom and associated controlled environment is about 5tims ~ 10times of that in
the high-grade hotel with the same area. Reasonably determining the matching among

Part 1. General Guidelines
1 Scope
This Part of GB/T 33556 specifies the specifications on the verification, operation
management, maintenance, and etc. of hospital cleanroom and associated controlled
This Part is applicable to the hospital cleanroom and associated controlled
environment like clean operating room, hematopoietic stem cell transplantation room,
reproduction center, burn ward, ICU ward, intravenous infusion preparation center.
