Scope
Main technical content: This standard specifies the calibration conditions, calibration items, and calibration methods for masks' ventilation resistance and pressure difference detectors, as well as the uncertainty evaluation of the calibration results. This standard is applicable to the calibration of masks' ventilation resistance and pressure difference detectors (or masks' ventilation resistance testers) used for detecting the pressure difference (or ventilation resistance) of medical surgical masks and disposable medical masks. Other detectors based on the same principle can be calibrated in accordance with this standard.
