    Existing pump test procedures for determining the anti-wear properties of hydraulic fluids are expensive to undertake, have a long test duration and require a large quantity of test fluid. This paper describes a project to develop an alternative low cost bench screening procedure of short duration, requiring only a small quantity of test fluid and using simple reproducible test specimens. A high level of correlation is demonstrated between the new test method and existing vane pump test procedures for a range of hydraulic fluids including mineral oils and water-glycol fluids. The new test procedure is highly suited to the hydraulic fluid development process requiring only ten litres of fluid per test and a maximum total test duration of six hours.
