标准摘要
[中文适用范围]： ISO 18437 的这一部分确立了 ISO 18437-2 至 ISO 18437-5 的基本原则，用于测定各向同性粘弹性弹性体的动态机械性能（即弹性模量、剪切模量、体积模量、损耗因子和泊松比）隔振器中使用的材料来自实验室测量。 它还为选择本国际标准的适当部分提供帮助。 ISO 18437 的这一部分适用于振动隔离器中使用的各向同性弹性材料，以减少： a) 音频振动向结构的传输，该结构可以辐射流体传播的声音（空气传播的、结构传播的声音）或其他）; b) 低频振动的传输，例如，当振动过于剧烈时，低频振动可能作用于人体或对结构或敏感设备造成损坏； c) 冲击和噪声的传递。 通过 ISO 18437 本部分概述并在 ISO 18437-2 至 ISO 18437-5 中进一步规定的测量方法获得的数据可用于： 1) 高效隔振器的设计； 2）为给定的设计选择最佳的弹性材料； 3）通过隔振器传递振动的理论计算； 4）产品开发过程中的信息； 5）制造商和供应商提供的产品信息； 6）质量控制。 [外文原描述]： ISO 18437-1:2012 establishes the principles underlying ISO 18437-2 to ISO 18437-5 for the determination of the dynamic mechanical properties (i.e. elastic modulus, shear modulus, bulk modulus, loss factor, and Poisson ratio) of isotropic visco-elastic resilient materials used in vibration isolators from laboratory measurements. It also provides assistance in the selection of the appropriate part of this International Standard. ISO 18437-1:2012 is applicable to isotropic resilient materials that are used in vibration isolators in order to reduce: a) the transmissions of audio frequency vibrations to a structure that can, for example, radiate fluid-borne sound (airborne, structure-borne or other); b) the transmission of low frequency vibrations which can, for example, act upon humans or cause damage to structures or sensitive equipment when the vibration is too severe; c) the transmission of shock and noise. The data obtained with the measurement methods that are outlined in ISO 18437-1:2012 and further specified in ISO 18437-2 to ISO 18437-5 can be used for: 1) the design of efficient vibration isolators; 2) the selection of an optimum resilient material for a given design; 3) the theoretical computation of the transfer of vibrations through vibration isolators; 4) information during product development; 5) product information provided by manufacturers and suppliers; 6) quality control.
