标准范围
本文件规定了以下程序:a) 1μm(c)及更大粒径的主要粒度校准,能够分析瓶样的液体自动颗粒计数器的传感器分辨率和计数性能;b) 使用悬浮液进行二次粒度校准,用一次校准的APC进行验证;c) 建立可接受的操作和性能限制;d) 使用测试粉尘验证颗粒传感器性能;e) 确定一致性和流量限制。本文件适用于液压油、航空和柴油、发动机机油和其他石油基液体。本文件不适用于使用NIST?SRM?2806b主要校准悬浮液的粒度校准。
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.
