常用的试验方法为静水试压，即：向封闭的管段充水，然后把管段升压至规定压力，检查是否泄漏。

A common approach is hydrostatic testing-filling a closed pipeline section with water, then pressurizing the line to a specified pressure to check for leaks.

试验结果表明，新型滤器的压力降完全符合规定要求，原始滤清效率为63.04%，而传统滤器的原始滤清效率仅为60%。

The test results show that the pressure descend of new filter conform to the requirement of standard, the filtration efficiency is 63.04%, and the traditional filter is no less than 60%.

同时也可用本计算公式来校验设计文件规定的试验压力。

Meanwhile, this formula can be also used to verify the test pressure specified by the design document.
