环境试验.第2-6部分:试验.试验Fc:振动(正弦波)

[中文适用范围]： IEC 60068 的这一部分给出了一种测试方法，该方法提供了确定组件、设备和其他物品（以下称为样本）承受指定强度的正弦振动的能力的标准程序。如果一个物品要以无包装的形式进行测试，即没有包装，则它被称为测试样本。然而，如果物品被包装，则物品本身被称为产品，物品及其包装一起被称为测试样本。该测试的目的是确定样本指定性能中的任何机械弱点和/或退化，并使用此信息与相关规范结合来决定样本的可接受性。在某些情况下，测试方法也可用于证明样本的机械鲁棒性和/或研究其动态行为。组件的分类也可以根据测试中引用的严重性进行选择。 [外文原描述]： Gives a method of test which provides a standard procedure to determine the ability of components, equipment and other articles, hereinafter referred to as specimens, to withstand specified severities of sinusoidal vibration. If an item is to be tested in an unpackaged form, that is without its packaging, it is referred to as a test specimen. However, if the item is packaged then the item itself is referred to as a product and the item and its packaging together are referred to as a test specimen. The purpose of this test is to determine any mechanical weakness and/or degradation in the specified performance of specimens and to use this information, in conjunction with the relevant specification, to decide upon the acceptability of the specimens. In some cases, the test method may also be used to demonstrate the mechanical robustness of specimens and/or to study their dynamic behaviour. Categorization of components can also be made on the basis of a selection from within the severities quoted in the test. The major changes with regard to the previous edition concern: - Reference to the latest version of IEC 60068-2-47:Mounting - Simplification of the layout of the standard by replacing some tables with text. - Addition of the test report requirements (see Clause 13).
