3 Terms and definitions
For the purposes of this document, the terms and definitions given in YY 0569 and JG 170 as well as the followings apply.
3.1
biosafety performance of equipment
equipment performance that protects people and the environment from pathogenic microbial hazards
3.2
animal isolated equipment
general term for negative pressure isolation devices used in animal biosafety laboratories to prevent the leakage of pathogenic microorganisms, effectively prevent animal escape, and breed animals
Note: It is revised from GB 50346-2011, Definition 2.0.9.
3.3
individually ventilated cage, IVC
individually ventilated containment barrier with breeding box as the unit; wherein, clean air is delivered into each independent cage to maintain a certain pressure and cleanliness in the breeding environment, so as to avoid animal pollution by the environment (positive pressure) or environmental pollution by animals (negative pressure)
Note 1: It is revised from GB 50346-2011, Definition 2.0.8.
Note 2: This equipment is used to breed animals that are clean and specific pathogen-free or non-infected (free of negative pressure) . The negative pressure individually ventilated cage is used to breed infected animals in the biosafety laboratory.
3.4
gas (vapor) disinfection equipment
equipment used to kill or clear pathogenic microorganisms on a transmission medium by the gas (vapor) generated by disinfectant to achieve disinfection
3.5
airtight door
airtight door usually with leaf and frame integrated, and with gap sealed by a mechanical pressing device or an inflatable sealing ring
Note: It is revised from GB 50346-2011, Definition 2.0.10.
3.6
exhaust high efficiency filtration units
filtration unit used in specific biorisk environment to remove harmful bio-aerosol in exhaust, which has the functions of in-situ disinfection and leak detection
