ACFTD停止生产后 ,国际标准化组织决定采用一种新的标准粉末—— ISO MTD来取代ACFTD,并同时修订和重新制定了与之相关的国际标准。文章阐述了标准粉末改变后 ,对液压系统污染控制和过滤器测试来说 ,究竟产生了哪些变化 ,为什么会产生这些变化 ,这些变化对污染度等级和过滤比会产生什么样的影响 ,以及我国液压污染控制界应该怎么办等。
After ACFTD ceased production, the International Organization for Standardization decided to replace the ACFTD with a new standard powder, the ISO MTD, with the revision and reformulation of international standards related thereto. The paper explains exactly what changes have occurred to the hydraulic system’s pollution control and filter tests since the standard powder was changed, why these changes have occurred, how these changes have affected the pollution levels and filtration rates, and how our country Hydraulic pollution control community should be how to do so.
