[中文适用范围]： 本文件涉及一项测试，用于在特定的温度、湿度和空气流动条件下，模拟叶类蔬菜在测试区域中的重量损失。该测试仅适用于尺寸大于200 mm × 150 mm × 100 mm（长×宽×高）的空间。该测试的目的是通过测量测试托盘在测试前和给定持续时间后的重量，来测量重量损失率。注：重量损失是产品保质期的考虑因素之一。其他考虑因素（如冷凝）将在未来的修订中处理。 [外文原描述]： IEC 63169:2020 deals with a test to simulate the weight loss of leafy produce, given certain conditions of temperature, humidity and air movement in one or more test zones. The test can only be applied to spaces larger than 200 mm × 150 mm ×100 mm (L × W × H). The aim of the test is to measure the weight loss rate by measuring the weight of a test tray prior to the test and after a given duration. Weight loss is one of the considerations for shelf life of produce. Other considerations such as condensation will be addressed in future amendments.
