Abstract: Objective　According to national standard Laboratory Animal-Environment and Housing Facilities, the operational test indicators which did not meet the criteria of experiment facility in barrier environment were analyzed to provide references for management and maintenance of laboratory animal facilities.Methods　According to appendices A-D and G-I of Laboratory Animal-Environment and Housing Facilities,temperature, relative humidity, air velocity, air exchange rate, static differential pressure, noise, animal illuminance, working illuminance and ammonia concentration of the barrier facilities were tested.Results　All indicators failed to meet the national standard requirements for barrier facilities except air velocity, including temperature, relative humidity, air exchange rate, static differential pressure, noise, animal illuminance, working illuminance and ammonia concentration. Among them, the failure rate of static differential pressure reached 91.3%. Conclusion　Choosing appropriate air conditioning system,maintaining ventilation ducts and exchanging various level of filters in time provide effective guarantee for experiment facilities in barrier environment to conform to national standard.

摘要： 目的　根据国家标准《实验动物 环境及设施》,对动态检测不符合屏障环境标准的检测指标进行统计与分 析,为实验动物设施的日常管理和维护提供参考。方法　对屏障环境设施的温度、相对湿度、气流速度、换气次数、 静压差、噪声、动物照度、工作照度和氨浓度按照国家标准《实验动物 环境及设施》附录A-D和附录G-I进行检测。 结果　除气流速度外,温度、相对湿度、换气次数、静压差、噪声、动物照度、工作照度和氨浓度均存在不符合屏障环 境设施国家标准要求的情况,其中静压差的不合格率达91.3%。结论　选择适宜的空调系统,对送、排风管道和各 级过滤器的及时维护和更换,是实验动物屏障环境设施符合国家标准要求的有力保证。
