液压传动.液体自动颗粒计数器的校准

[中文适用范围]： 本文件规定了以下程序： a) 粒径为 1 µm(c) 及以上的初级粒径校准、能够分析瓶子样品的液体自动颗粒计数器的传感器分辨率和计数性能； b) 使用经初级校准 APC 验证的悬浮液进行二级粒径校准； c) 建立可接受的操作和性能限制； d) 使用测试灰尘验证颗粒传感器的性能； e) 确定重合度和流量限制。 本文件适用于液压油、航空燃料和柴油燃料、发动机油和其他石油基液体。 本文件不适用于使用 NIST SRM 2806b 初级校准悬浮液进行颗粒大小校准。 [外文原描述]： This document specifies procedures for the following: a) primary particle-sizing calibration for particle sizes 1 µm(c) and larger, sensor resolution and counting performance of liquid automatic particle counters that are capable of analysing bottle samples; b) secondary particle-sizing calibration using suspensions verified with a primary calibrated APC; c) establishing acceptable operation and performance limits; d) verifying particle sensor performance using a test dust; e) determining coincidence and flow rate limits. This document is applicable for use with hydraulic fluids, aviation and diesel fuels, engine oil and other petroleum-based fluids. This document is not applicable to particle-sizing calibration using NIST SRM 2806b primary calibration suspensions.
