Utility-interconnected photovoltaic inverters - Test procedure for low voltage ride-through measurem...
IEC TS 62910:2015(E) provides a test procedure for evaluating the performance of Low Voltage Ride-Through (LVRT) functions in inverters used in utility-interconnected PV systems. The technical specification is most applicable to large systems where PV inverters are connected to utility HV distribution systems. However, the applicable procedures may also be used for LV installations in locations…
Photovoltaic (PV) array - On-site measurement of current-voltage characteristics
IEC 61829:2015 specifies procedures for on-site measurement of flat-plate photovoltaic (PV) array characteristics, the accompanying meteorological conditions, and use of these for translating to standard test conditions (STC) or other selected conditions. This new edition includes the following significant technical changes with respect to the previous edition:
- it addresses many outdated…
Champ de modules photovoltaïques (PV) - Mesurage sur site des caractéristiques courant-tension
L'IEC 61829:2015 spécifie les procédures relatives au mesurage sur site des caractéristiques d'un champ de modules photovoltaïques (PV) à plaque plane avec les conditions climatiques associées et l'utilisation de celles-ci pour leur transposition dans des conditions normales d'essai (STC - standard test conditions) ou dans d'autres conditions sélectionnées. Cette nouvelle…

ISO 19901-1:2015 gives general requirements for the determination and use of meteorological and oceanographic (metocean) conditions for the design, construction and operation of offshore structures of all types used in the petroleum and natural gas industries.
The requirements are divided into two broad types:
- those that relate to the determination of environmental conditions in general,…
Cigarettes — Determination of loss of tobacco from the ends — Part 3: Method using a vibro-bench
ISO/TS 3550-3:2015 specifies a method for the determination of loss of tobacco from cigarette ends using a vibro-bench.
This method applies to the determination of loss of tobacco from cigarette ends in manufacturing site, throughout the distribution network and also while in the smoker's pocket.
NOTE Two other methods for the determination of loss of tobacco from the ends, using a…
