IEC 63203-402-3:2024规定了术语、测量协议和测试，以评估使用光体积描记术（PPG）传感器测量心率的可穿戴设备的准确性。虽然本文件可用于测量声称报告心率的各种不同设备，但在区分心率和脉搏率的国家进行测试时，应格外小心。本测量协议不用于评估与IEC 60601系列或ISO 80601系列相关的医疗器械。

IEC 63203-402-3:2024 specifies terms, a measurement protocol, and a test to evaluate the accuracy of wearables that measure heart rate with a photoplethysmography (PPG) sensor. While this document can be used to measure a variety of different devices claiming to report heart rate, care will be taken when testing in countries that differentiate between heart rate and pulse rate. This measurement protocol is not intended to evaluate medical devices associated with the IEC 60601 series or ISO 80601 series.
