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初级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.
