IEC 62951-7:2019规定了评估条件，并给出了测量方法和测试装置，用于测量具有ultra在平坦和弯曲条件下的低渗透速率。本文件还包括试样的制备、电触点、传感器薄膜和计算程序。为此，本文件提供了术语、定义、符号、配置和测试方法，包括温度、相对湿度、测试时间等测试条件。

IEC 62951-7:2019 specifies evaluation conditions and gives a method of measurement as well as a test set-up for the measurement of barrier performance for thin-film layer with ultra？low permeation rate under both flat and bending conditions. This document also includes the preparation of specimen, electrical contacts, sensor films and calculation procedures. For these purposes, this document provides terms, definitions, symbols, configurations, and test methods including test conditions such as temperature, relative humidity, testing time.
