Обзор требований
Этот обзор пока доступен только на английском языке.
Область применения
This standard applies to the design, construction, testing, acceptance, and supervision of laboratory animal facilities used for breeding, production, and experimentation. It covers environments for various animal grades, including conventional, SPF, and germ-free animals. It is mandatory for all new and existing facilities housing laboratory animals in China. The standard does not apply to general agricultural animal housing that is not used for scientific research.
Технические требования
The standard classifies environments into conventional, barrier, and isolation categories based on air purification control levels. It specifies critical environmental indicators such as temperature, relative humidity, air change rates, and airborne particle cleanliness classes (ranging from Class 5 to Class 8) for different animal species. Facility designs must strictly separate human, animal, and material flows to prevent cross-contamination. For facility infrastructure, the standard outlines requirements for architectural structures, HVAC systems, electrical supply, and automatic control systems. Barrier environments must maintain specific pressure differentials and use sealed lighting fixtures. Facilities must also implement comprehensive waste treatment protocols for sewage, animal carcasses, and contaminated bedding. Additionally, the standard emphasizes animal welfare, specifying minimum floor areas and cage heights for common laboratory animals like mice, rats, dogs, and non-human primates. Transportation requirements mandate strict temperature control, biosecurity measures, and appropriate container specifications to ensure animal safety.
Методы испытаний
The standard outlines specific testing procedures, primarily conducted under static conditions (without animals) for parameters like particle counts and pressure differentials, and dynamic conditions (with animals) for ammonia levels. Key tests include temperature and humidity measurement, airflow velocity, air exchange rate calculation, and static pressure difference testing. Comprehensive testing is required upon facility completion and after any major system modifications. Airborne particle counters and microbial settling plates are utilized to verify cleanliness classes and biological contamination levels.
Частые вопросы
