1.1本试验方法包括通过在产品安装表面施加水平线性正弦运动来测定未包装产品和部件的共振。产品的垂直振动测试见方法D3580。提出了两种替代试验方法: 1.1.1试验方法A-使用正弦振动进行共振搜索，以及 1.12试验方法B-使用随机振动进行共振搜索。 1.2当产品共振在预期的运输环境频率范围内时，该信息可用于检查产品对振动的响应，以用于产品设计目的，或用于设计将在临界频率下最小化运输振动输入的容器或内部包装。由于振动损伤最有可能发生在产品共振频率处，因此这些可能被视为潜在的产品脆弱点。 1.3从可选正弦驻留和随机试验方法获得的信息可用于评估共振部件的疲劳特性和产品修改。如果产品的响应需要设计不切实际或成本过高的运输集装箱，则这可能是必要的。 1.4本试验方法不一定模拟产品在操作或最终使用环境中会遇到的振动效应。为此，应使用其他更合适的测试程序。 1.5 S1单位中规定的值应视为标准值。括号中给出的值仅供参考。 1.6本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 有关具体的预防说明，请参阅第6节。

1.1 This test method covers the determination of resonances unpackaged products and components by means of horizontal linear sinusoidal motion applied at the surface on which the product is mounted. For vertical vibration testing of products see Method D3580. Two alternate test methods are presented: 1.1.1 Test Method A - Resonance Search Using Sinusoidal Vibration, and 1.12 Test Method B - Resonance Search Using Random Vibration. 1.2 This information may be used to examine the response of products to vibration for product design purposes, or for the design of a container or interior package that will minimize transportation vibration inputs at the critical frequencies, when the product resonances are within the expected transportation environment frequency range. Since vibration damage is most likely to occur at product resonant frequencies, these may be thought of as potential product fragility points. 1.3 Information obtained from the optional sinusoids dwell and random test methods may be used to assess the fatigue characteristics of the resonating components and for product modification. This may become necessary if a product's response would require design of an impractical or excessively costly shipping container. 1.4 This test method does not necessarily simulate vibration effects the product will encounter in operating or end-use environments. Other, more suitable test procedures should be used for this purpose. 1.5 The values stated in S1 units are to be regarded as the standard. The values given in parentheses are for information only. 1.6 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 6.
