Reference substance for detecting permeation and leakage amount of steam and gas and preparation method of reference substance

The invention discloses a reference substance for detecting the permeation and leakage amount of steam and gas and a preparation method of the reference substance. The preparation method comprises thefollowing steps that a substrate whose barrier property or sealing performance satisfies a preset standard is selected; and the substrate is punched according to the preset standard to obtain the reference substance. According to the reference substance and the preparation method thereof, the reference substance with uniform performance can be obtained according to needs, and detection parametersof a detection instrument can be calibrated accurately. 本发明公开了一种用于检测水蒸气及气体的透过和泄漏量的标准物及其制备方法，用于检测水蒸气及气体的透过量和泄漏量的标准物的制备方法包括以下步骤：选取阻隔性或密封性符合预设标准的基材；对所述基材按预设标准进行打孔处理，得到所述标准物。用于检测水蒸气及气体的透过量和泄漏量的标准物及其制备方法，能够根据需要得到性能统一的标准物，能够对检测仪器的检测参数进行准确的校准。
