标准摘要
[中文适用范围]： IEC 60704-2-14:2013+AMD1:2019+AMD2:2024 CSV 规定了测量条件，以便在确定发出的噪声和比较不同实验室测量结果时提供足够的精度，同时尽可能模拟实际情况。使用家用冰箱、冷冻食品储藏柜和食品冷冻柜。建议考虑将噪声级的测定作为综合测试程序的一部分，涵盖家用冰箱、冷冻食品储藏柜和食品冷冻柜的特性和性能的许多方面。相对于前一版本，本版本包括以下重大技术变化： a) 适当测试外壳的描述已从 IEC 60704 的本部分中删除，并已合并到 IEC 60704-1 的第 1 部分中； b) 增加了根据IEC 60704本部分确定的声功率级标准偏差值。该合并版本由第二版（2013年）及其修正案1（2019年）组成。因此，无需对本出版物进行修订。本出版物应与 IEC 60704-1:2010 一起阅读。 [外文原描述]： IEC 60704-2-14:2013+AMD1:2019+AMD2:2024 CSV specifies the measuring conditions to provide for sufficient accuracy in determining the noise emitted and comparing the results of measurements taken by different laboratories, whilst simulating as far as possible the practical use of household refrigerators, frozen-food storage cabinets and food freezers. It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of the properties and performance of household refrigerators, frozen-food storage cabinets and food freezers. This edition includes the following significant technical changes with respect to the previous edition: a) the description of an appropriate test enclosure has been removed from this part of IEC 60704 and has been incorporated into Part 1 of IEC 60704-1; b) the values of standard deviations of sound power levels determined according to this part of IEC 60704 have been added. This consolidated version consists of the second edition (2013) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication. This publication is to be read in conjunction with IEC 60704-1:2010 .
