ISO 23747:2015规定了用于评估自主呼吸人类肺功能的呼气峰值流量计（pefm）的要求。 ISO 23747:2015涵盖了作为综合肺功能医疗设备的一部分或作为独立医疗设备测量自发呼吸人体呼气峰值流速的所有医疗设备。 应用于国际标准的产品的规划和设计是考虑产品在其生命周期中对环境的影响。附件E阐述了环境方面的问题。 注:ISO 14971阐述了环境影响的其他方面。

ISO 23747:2015 specifies requirements for a peak expiratory flow meter (pefm) intended for the assessment of pulmonary function in spontaneously breathing humans. ISO 23747:2015 covers all medical devices that measure peak expiratory flowrate in spontaneously breathing humans either as part of an integrated lung function medical device or as a stand-alone medical device. Planning and design of products applying to this International Standard are to consider the environmental impact from the product during its life cycle. Environmental aspects are addressed in Annex E. NOTE Additional aspects of environmental impact are addressed in ISO 14971.
