ISO 18437-3:2005定义了一种悬臂剪切梁法，用于通过实验室测量确定隔振器中使用的弹性材料的动态机械性能。通过使用固定端避免因夹紧试样而产生的常见误差，因此梁端没有旋转运动。ISO 18437的本部分适用于从几分之一赫兹到大约20千赫的冲击和振动系统。ISO 18437-3:2005适用于用于隔振器的弹性材料，以减少--来自机器、结构或车辆的有害振动的传播，这些机器、结构或车辆发出声音（流体传播、空气传播、结构传播或其他），以及--低频振动的传播，当振动太严重时，作用于人或对结构或敏感设备造成损坏。使用ISO 18437-3:2005中概述的测量方法获得的数据用于--高效隔振器的设计，--为给定设计选择最佳材料，--通过隔离器传递振动的理论计算，--产品开发过程中的信息，--制造商和供应商提供的产品信息，以及--质量控制。

ISO 18437-3:2005 defines a cantilever shear beam method for determining from laboratory measurements the dynamic mechanical properties of the resilient materials used in vibration isolators. Common errors due to clamping the specimen are avoided by using fixed ends so there is no rotational motion of the beam at its ends. This part of ISO 18437 is applicable to shock and vibration systems operating from a fraction of a hertz to about 20 kHz.ISO 18437-3:2005 is applicable to resilient materials that are used in vibration isolators in order to reduce-- transmissions of unwanted vibrations from machines, structures or vehicles that radiate sound (fluid-borne, airborne, structure-borne, or other), and-- the transmission of low- frequency vibrations that act upon humans or cause damage to structures or sensitive equipment when the vibration is too severe.The data obtained with the measurement methods that are outlined in ISO 18437-3:2005 are used for-- the design of efficient vibration isolators,-- the selection of an optimum material for a given design,-- the theoretical computation of the transfer of vibrations through isolators,-- information during product development,-- product information provided by manufacturers and suppliers, and-- quality control.
