This International Standard specifies methods and procedures for free-field calibration of hydrophones, as well as individual electroacoustic transducers that can be used as hydrophones (receivers) and/or projectors (source transducers). Two general types of calibration are covered within this standard: absolute calibration using the method of three-transducer spherical-wave reciprocity, and relative calibration by comparison with a reference device which has already been the subject of an absolute calibration.

The maximum frequency range of the methods described in this standard is from 200 Hz to 1 MHz. The lowest acoustic frequency of application will depend on a number of factors, and will typically be in the range 200 Hz to 5 kHz depending mainly on the dimensions of the chosen test facility, The highest frequency of application for the methods described here is 1 MHz.

Procedures for pressure hydrophone calibration at low frequencies can be found in IEC 60565-2 [1]. Procedures for hydrophone calibration at acoustic frequencies greater than 1 MHz are covered by IEC 62127-2 [2].

Excluded from the scope of this standard are low frequency pressure calibrations of hydrophones, which are described in IEC 60565-2 [1]. Also excluded are calibrations of digital hydrophones and systems, calibration of marine autonomous acoustic recorders, calibration of vector sensors such as particle velocity sensors and pressure gradient hydrophones, calibration of passive sonar arrays consisting of multiple hydrophones, and calibration of active sonar arrays consisting of projectors and hydrophones.

This standard presents a description of the requirements for free-field calibration in terms of test facility, equipment and instrumentation, signal processing, and frequency limitations. A description of achievable uncertainty and rules for the presentation of the calibration data are provided. Also included are informative annexes that provide additional guidance. Annex A provides guidance on measurement of directional response of a hydrophone or projector. Annex B provides guidance on measurement of electrical impedance of hydrophones and projectors. Annex C provides guidance on electrical loading corrections. Annex D provides guidance on acoustic far-field criteria in underwater acoustic calibration. Annex E provides guidance on pulsed techniques in free-field calibrations. Annex F provides guidance on assessment of uncertainty in the free-field calibration of hydrophones and projectors. Annex G describes the derivation of the formulae for three-transducer spherical-wave reciprocity calibrations. Annex H provides guidance on calibration using travelling wave-tubes. Annex I provides guidance on calibration of hydrophones using optical interferometry. And finally, Annex J provides guidance on calibrations in reverberant water tanks using continuous signals.

IEC standards for photovoltaic devices require the use of specific classes of solar simulators deemed appropriate for specific tests. Solar simulators can be either used for performance measurements of PV devices or endurance irradiation tests. This part of IEC 60904 provides the definitions of and means for determining simulator classifications at the required irradiance levels used for electrical stabilization and characterisation of PV devices.

 

This test standard is applicable for solar simulators used in PV test and calibration laboratories and in manufacturing lines of solar cells and PV modules. The A+ category is primarily intended for calibration laboratories and is not considered necessary for power measurements in PV manufacturing and in qualification testing. Class A+ has been introduced because it allows for reduction in the uncertainty of secondary reference device calibration, which is usually performed in a calibration laboratory. Measuring uncertainty in PV production lines will directly benefit from a lower uncertainty of calibration, because production line measurements are performed using secondary reference devices.

 

In the case of PV performance measurements, using a solar simulator of a particular class  does not eliminate the need to quantify the influence of the simulator on the measurement by making spectral mismatch corrections and analysing the influences of uniformity of irradiance in the test plane and temporal stability on that measurement. Test reports for PV devices tested with the simulator shall list the class of simulator used for the measurement and the method used to quantify the simulator’s effect on the results.

The purpose of this standard is to define classifications of solar simulators for use in indoor measurements of terrestrial photovoltaic devices. Solar simulators are classified as A+, A, B or C based on criteria of spectral distribution match, irradiance non-uniformity in the test plane and temporal instability. This standard provides the required methodologies for determining the classification of solar simulators in each of the categories.

A solar simulator which does not meet the minimum requirements of class C cannot be classified according to this standard.For spectral match classification a new procedure has been added. This procedure addresses the actual need for an extended wavelength range, which is arising from advances in solar cell technology (such as increased spectral responsivity below 400 nm) as well as solar simulator technology (use of component LEDs). The procedure of the second edition of this standard is still valid, but shall only be applied if backward compatibility of solar simulators already in use is required. This standard is referred to by other IEC standards, in which class requirements are laid down for the use of solar simulators.  The solar simulator characteristics described in this document should not be used in isolation to imply any level of measurement confidence or measurement uncertainty for a solar simulator application (for example, PV module power measurement). Measurement uncertainties in each application will depend on many factors, several of which are outside the scope of this standard:

Characteristics of the solar simulator, possibly including characteristics not covered by this standard;

Methods used to calibrate and operate the solar simulator;

Characteristics of the device(s) under test (for example, size and spectral response);

Quantities measured from the device(s) under test, including equipment and methods used for measurement;

Possible corrections applied to measured quantities.

When applications require a certain solar simulator characteristic, it is preferable to specify a numerical value rather than a letter classification (for example, “≤ 5 % non-uniformity of irradiance” rather than “Class B non-uniformity of irradiance”). If not obvious from the application, it should also be indicated how the required simulator characteristic correlates to relevant measured quantities. Since PV module power measurement is one of the most common applications for solar simulators, brief guidance on this application is given in informative notes for each solar simulator characteristic described in this document. This standard shall be used in combination with IEC TR 6XXXX, which deals with best practice recommendations for the intended use of a solar simulator. For output power characterization of PV devices, this Technical Report will address the relevance of the letter grades (A+, A, B, C) for measurement uncertainty.
