ISO 4548.7:2012规定了一种测试全流量润滑油过滤器结构完整性的方法,以承受发动机振动。本试验适用于最大流速为100 l/min的旋装式过滤器和带有一次性元件的可拆卸过滤器。
本试验方法适用于由材料制成的试验零件,这些材料在使用过程中的温度范围内不会发生机械性能变化。如果过滤器制造商和买方之间的协议认为适用,则该试验可适用于其他过滤器。
ISO 4548.7:2012 specifies a method of testing the constructional integrity of full-flow lubricating oil filters to withstand engine vibrations. This test is intended for application to spin-on type filters and detachable filters with disposable elements with a maximum flow rate of 100 l/min.
This test method is intended for test parts made from materials that do not experience mechanical property changes within the temperature range experienced in service. The test may be applied to other filters if thought applicable by agreement between the filter manufacturer and the purchaser.
