Technical committeeTypeAcronymIEC PAS 62257-10:2017CommitteePublished year2017Description
IEC PAS 62257-10:2017(E) is designed to be used as a guide to visually inspect front-contact poly-crystalline and mono-crystalline silicon solar photovoltaic (PV) modules for major defects. The modules under consideration may be of any size or rated power, however some specific use-cases for solar modules may have different requirements and therefore adaption of this document is application and institution dependent (ex. labelling may not be present for a solar module sold as part of a small off-grid lighting kit). This document is meant to supplement and support rather than replace international testing standards such as IEC 61215.

Consolidated versionCommitteePublished year2016KeywordsDescriptionIEC 62446-1:2016+A1:2018 defines the information and documentation required to be handed over to a customer following the installation of a grid connected PV system. It also describes the commissioning tests, inspection criteria and documentation expected to verify the safe installation and correct operation of the system. It is for use by system designers and installers of grid connected solar PV systems as a template to provide effective documentation to a customer. This new edition cancels and replaces IEC 62446 published in 2009 and includes the following significant technical change with respect to IEC 62446:2009: expansion of the scope to include a wider range of system test and inspection regimes to encompass larger and more complex PV systems. This consolidated version consists of the first edition (2016) and its amendment 1 (2018). Therefore, no need to order amendment in addition to this publication.

Technical committeeTypeAcronymIEC 62282-3-201CommitteePublished year2013Description
IEC 62282-3-201 provides test methods for the electrical, thermal and environmental performance of small stationary fuel cell power systems that meet the following criteria:
- rated electric power output of less than 10 kW;
- grid-connected/independent operation or stand-alone operation with single-phase AC output or 3-phase AC output not exceeding 1 000 V, or DC output not exceeding 1 500 V;
- maximum allowable working pressure of less than 0,1 MPa (gauge) for the fuel and oxidant passages;
- gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen, etc.) or liquid fuel (kerosene, methanol, etc.);
- air as oxidant.
This document describes type tests and their test methods only. This document covers fuel cell power systems whose primary purpose is the production of electric power.
This new edition includes the following significant technical changes with respect to the previous edition: revision of test set-up, revision of measurement instruments, introduction of ramp-up test, introduction of rated operation cycle efficiency, introduction of electromagnetic compatibility (EMC) test, revision of exhaust gas test, introduction of typical durations of operation cycles. -

IEC 62031:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
IEC 62031:2018 specifies general and safety requirements for light-emitting diode (LED) modules:
- non-integrated LED modules (LEDni modules) and semi-integrated LED modules (LEDsi modules) for operation under constant voltage, constant current or constant power;
- Integrated LED modules (LEDi modules) for use on DC supplies up to 250 V or AC supplies up to 1 000 V at 50 Hz or 60 Hz.

Technical committeeTypeAcronymIEC 62006CommitteePublished year2010Description
IEC 62006:2010 defines the test, the measuring methods and the contractual guarantee conditions for field acceptance tests of the generating machinery in small hydroelectric power installations. It applies to installations containing impulse or reaction turbines with unit power up to about 15 MW and reference diameter of about 3 m. The driven generator can be of synchronous or asynchronous type. This International Standard contains information about most of the tests required for acceptance of the hydraulic turbine such as safety approval tests, trial operating and reliability tests, as well for verification of cavitation, noise and vibration conditions, if required. This standard represents the typical methods used on smaller hydroelectric installations, and is divided into three classes as follows:
Class A: Default, normal test program (panel measurement), to determine the maximum output of the installation.
Class B: Recommended, extended test program, to determine the performance characteristics of the installation.
Class C: Optional, comprehensive test program, to determine the absolute efficiency of the installation.
All classes contain safety tests, trial operating tests, and reliability tests. This standard gives all necessary references for the contract in order to execute the test, evaluate, calculate and compare the result to the guarantee for all the classes A, B and C.Technology -

IEC 61730-2:2016 provides the testing sequence intended to verify the safety of PV modules whose construction has been assessed by IEC 61730-1. The test sequence and pass criteria are designed to detect the potential breakdown of internal and external components of PV modules that would result in fire, electric shock, and/or personal injury. The standard defines the basic safety test requirements and additional tests that are a function of the PV module end-use applications. Test categories include general inspection, electrical shock hazard, fire hazard, mechanical stress, and environmental stress. This new edition includes the following significant technical changes with respect to the previous edition:
- the test sequences have been rearranged;
- various tests have been detailed or added. -
