本文件规定了一种测试内燃机用金属压力容器材料制造的全流量润滑油过滤器承受内部压力波动能力的方法。通常情况下，发动机从冷态启动时会出现喘振，并且在运行过程中会出现周期性的内部压力变化。这些测试旨在应用于旋装式过滤器和带有一次性元件的可拆卸过滤器。如果认为适用，可通过过滤器制造商和买方之间的协议，将试验应用于其他过滤器。注:本试验不打算取代模拟环境试验（例如在非常低的温度下）。如果需要进行此类测试，则供应商和客户将就此进行协商。

This document specifies a method of testing the ability of full-flow lubricating oil filters manufactured with metal pressure vessel materials for internal combustion engines to withstand an internal pressure surge. Normally surges occur when an engine is started from cold, and cyclic internal pressure variations experienced during operation.These tests are intended for application to spin-on type filters and detachable filters with disposable elements.The tests can be applied to other filters, if thought applicable, by agreement between the filter manufacturer and the purchaser.NOTE This test is not intended to replace simulated environmental testing (e.g. at very low temperatures). If such testing is required, it will be the subject of negotiation between the supplier and customer.
