GB/T 18854-2015 in English

《GB/T 18854-2015液压传动 液体自动颗粒计数器的校准》由TC3（全国液压气动标准化技术委员会）归口，TC3SC4（全国液压气动标准化技术委员会液压污染控制分会）执行，主管部门为中国机械工业联合会。
本标准规定了液体自动颗计数器的校准方法和程序，包括：
a）对于可分析瓶装液样的液体自动颗粒计数器进行一级颗尺寸校准，测定计数性能和传感器分辨力；
b）使用经一级校准的液体自动颗粒计数器验证的悬浮液进行二级颗粒尺寸校准；
c）确定合格的工作范围和性能极限；
d）使用RM 8632校验颗粒传感器的性能；
e）测定重合误差极限和流量极限。

Scope

This standard specifies the calibration methods and procedures for liquid automatic particle counters, including: a) Perform primary particle size calibration for liquid automatic particle counters that can analyze bottled liquid samples, and measure counting performance and sensor resolution; b) Use primary-level particle size calibration; Calibrated liquid automatic particle counter verified suspension for secondary particle size calibration; c) determination of acceptable operating range and performance limits; d) verification of particle sensor performance using RM 8632; e) determination of coincidence error limits and flow limits.
