In order to verify the working reliability of hydraulic pulsation attenuator under the conditions of the specified high temperature，middle temperature and low temperature environment，the two different working hydraulic mediums and the same hydraulic system，a reasonable and feasible test method for working cycle life of the hydraulic pulsation attenuator was proposed.It satisfies the test requirements，the verification purpose is achieved.Meanwhile，the resources and cost of the test are saved，the test period is shortened.It can be used for other similar test products for reference.
