Hydraulic fluid power - Calibration of automatic particle counters for liquids
ISO 11171:2022

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.

Hydrometry - Specification for a reference raingauge pit
EN 13798:2010

This European Standard specifies the design of a reference raingauge pit. The reference raingauge pit is designed for the liquid precipitation only. The specified details of the pit and the grating, are purposely kept to a minimum in order to allow each raingauge operator latitude in their construction and to suit local conditions.

Reflectivity of electromagnetic wave absorbers in millimetre wave frequency - Measurement methods

IEC 62431:2008 specifies the measurement methods for the reflectivity of electromagnetic wave absorbers (EMA) for the normal incident, oblique incident and each polarized wave in the millimetre-wave range. In addition, these methods are also equally effective for the reflectivity measurement of other materials:
- measurement frequency range: 30 GHz to 300 GHz;
- reflectivity: 0 dB to -50 dB;
- incident angle: 0° to 80°. It replaces and cancels IEC/PAS 62431. This bilingual version published in 2011-11, corresponds to the English version published in 2008-07.

SIST EN ISO 3745:2004

Specification of two laboratory methods for determining the sound power level of a source. It gives requirements for the test room, as well as the source location, operating conditions and instrumentation. Techniques are specified for obtaining an estimate of the surface sound pressure level from which the weighted sond power level of the source as well as the sound power level in octave or one-third octave bands may be calculated. It is intended to prescribe techniques for acoustical measurments that may be used in test codes for particular types of equipment.
