GB/T 25916.1-2010 Cleanrooms and associated controlled environments - Biocontamination Control - Part 1: General principles and methods
1 Scope
This part of GB/T 25916 establishes the principles and basic methodology of a formal system of biocontamination control for assessing and controlling biocontamination when cleanroom technology is applied for that purpose. This part specifies the methods required for monitoring risk zones in a consistent way and for applying control measures appropriate to the degree of risk involved. In zones where risk is low, it can be used as a source of information.
Application-specific requirements are not given. Neither are fire and safety issues addressed; for these, see regulatory requirements and other national or local documentation.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 General
3.1.1
action level
level set by the user in the context of controlled environments, which, when exceeded, requires immediate intervention, including investigation of cause, and corrective action
3.1.2
alert level
level set by the user in the context of controlled environments, giving early warning of a drift from normal conditions, which, when exceeded, should result in increased attention to the process
3.1.3
bioaerosol
dispersed biological agents in a gaseous environment
3.1.4
biocontamination
contamination of materials, devices, individuals, surfaces, liquids, gases or air with viable particles
3.1.5
cleanroom
room in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation, and retention of particles inside the room, and in which other relevant parameters, e.g. temperature, humidity and pressure, are controlled as necessary
[GB/T 25915.1-2010, Definition 2.1.1] [2]
3.1.6
contact device
specially designed appliance holding an appropriate, sterile, culture medium with an accessible surface used for surface sampling
3.1.7
contact plate
contact device where the container is a rigid dish
3.1.8
control point
point in a controlled environment at which control is applied and a hazard can be prevented, eliminated or reduced to acceptable levels
3.1.9
controlled environment
defined zone in which sources of contamination are controlled by specified means
3.1.10
corrective action
action to be taken when the results of monitoring indicate that alert or action levels are exceeded
3.1.11
formal system
system of biocontamination control with established and documented procedures
3.1.12
hazard
potential source of harm
