This Recommended Practice (RP) addresses the sizing and counting of submicrometer liquid-borne particles using optical discrete-particle counters with a focus on applications in the semiconductor, flat-panel display, and data storage industries. Topics covered include...
For instruments working on the light obscuration principle.
This standard describes the sampling procedures and methods for the determination of particle concentration and size distribution. Three methods are specified. One uses an automatic particle size analyser, working on the light interruption principle. The other two use an optical...

This document establishes methods to: - validate equipment used to prepare secondary calibration suspensions for automatic particle counters; - perform online secondary calibration of automatic particle counters; - match two or more online particle counters, i.e. to...
This International Standard specifies an automatic particle counting procedure for determining the number and sizes of particles present in hydraulic-fluid bottle samples of clear, homogeneous, single-phase liquids using an automatic particle counter (APC) that...
Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose. This standard is to be used to determine the structural density of woven and knitted...
La presente Norma descrive le procedure per il campionamento e i metodi per la determinazione della concentrazione e della distribuzione dimensionale delle particelle in oli isolanti. La Norma specifica tre diversi metodi per misurare la concentrazione e la distribuzione dimensionale delle...
1.1 This test method covers the determination of particle concentration and particle size distribution in mineral insulating oil. It is suitable for testing oils having a viscosity of 6 to 20 cSt at 40°C. The test method is specific to liquid automatic particle analyzers...
