　　【化工仪器网政策标准】恒温恒湿实验室一般由恒温库体、空调系统和温湿度控制系统三部分构成。实验室外侧安置柜式风冷独立空调机组，一般采用横向送风方式，送风经顶部夹层通过孔板送出，回风经孔板吸入空气处理箱，确保室内温湿度场均匀，风速及温度梯度满足规程、规范和标准要求。对室内工况调节时，可设定室内控制温度及湿度，开启制冷，控制系统根据室内实时环境温度、湿度自动调节加热功率及加湿功率，达到温湿度平衡。

　　恒温恒湿实验室是开展计量检定、校准、检验检疫、检测、测试、科学研究和工业生产活动的重要环境条件。当前，在计量领域对于恒温恒湿实验室的要求有较为统一的常规要求，对于一些要求较高的精密实验室还有一些特殊的要求，然而目前没有可参照的技术依据，因此，为了统一和规范恒温恒湿实验室环境参数评价方法，正确指导恒温恒湿实验室的使用和维护，有必要制定全国统一的恒温恒湿实验室计量性能校准规范。

　　近日，按照全国温度技术委员会的要求，浙江省计量科学研究院承担的《恒温恒湿实验室环境参数校准规范》的制定工作已初步完成了正文编写和部分实验工作，并面向全社会对此《校准规范》进行意见征求工作。该项新的校准规范适用于恒温恒湿实验室(以下简称实验室)环境参数的校准，不适用于生物安全实验室以及医学实验室的校准。

　　关于实验室的计量特性，标准明确：实验室的环境参数主要包含温湿度偏差、温湿度短期稳定性、温湿度长期稳定性、温湿度均匀度、照度、工作区截面风速、风量、空气洁净度等级、噪声、静压差等，其技术要求主要依据使用方与实验室设计施工方所签订的技术协议，或者由使用方的实际需求提出。

　　实验室校准的环境条件包括温度：15 ℃~35 ℃；湿度：不大于 85% RH；气压：80 kPa~1060 kPa。测量标准有温度测量标准、湿度测量标准，校准过程中采用的其他仪器设备有照度测量仪器、工作区截面风速测量仪器、风量测量仪器、空气洁净度等级测量仪器、噪声测量仪器、静压差测量仪器。

　　关于实验室的校准项目，标准指出：根据实验室的设计要求以及使用方的使用需求确定，一般包含温湿度偏差、温湿度短期稳定性、温湿度长期稳定性、温湿度均匀度、照度、工作区截面风速、风量、空气洁净度等级、噪声、静压差等校准项目。

　　上述校准规范在制定的过程中引用参考了GB 50073-2013《洁净厂房设计规范》、GB 51110-2015《洁净厂房施工及质量验收规范》、GB 50243-2016《通风与空调工程施工质量验收规范》、GB/T 5700-2008《照明测试方法》、T/CECS 644-2019《恒温恒湿实验室工程技术规程》以及JJF 1101-2019《环境试验设备温度、湿度参数校准规范》。
