Utility-interconnected photovoltaic inverters - Test procedure for under voltage ride-through measur...
IEC TS 62910:2020 provides a test procedure for evaluating the performance of Under Voltage Ride-Through (UVRT) functions in inverters used in utility-interconnected Photovoltaic (PV) systems. This document is most applicable to large systems where PV inverters are connected to utility high voltage (HV) distribution systems. However, the applicable procedures may also be used for low voltage (LV…

Intelligent transport systems — Common Transport Service Account Systems — Part 1: Framework and use...
This document describes the characteristics of a Common Transport Service Account System (CTSA). It presents the common transport service account framework and associated use cases. The objective of the CTSA role model is to cover relevant transport services, the payment methods, the account types where the user of the service is charged for the service and that requires a more overall role and…
Rubber, vulcanized — Guidelines for material specification
This document establishes guidelines for the specification of vulcanized rubber based on the properties of individual rubber types. This document helps users of rubber products, who are not rubber experts, to create a specification for the rubber materials they wish to use.
It also describes a designation system to enable a line call-cut code to be devised for each specification.
Since the…
Surface mounting technology - Part 1: Standard method for the specification of surface mounting comp...
IEC 61760-1:2020 defines requirements for component specifications of electronic components that are intended for usage in surface mounting technology. To this end, it specifies a reference set of process conditions and related test conditions to be considered when compiling component specifications.
The objective of this document is to ensure that a wide variety of SMDs can be subjected to the…
Plastics hoses and hose assemblies — Textile-reinforced types for hydraulic applications — Specifica...
This document specifies requirements for three types of textile-reinforced thermoplastics hoses and hose assemblies of nominal size from 3,2 to 25. Each type is divided into two classes dependent on electrical conductivity requirements.
They are suitable for use with:
— oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743‑4 at temperatures ranging from −40 °C to +93 °C…
Rice — Determination of amylose content — Part 1: Spectrophotometric method with a defatting procedu...
This document specifies a reference method for the determination of the amylose content of milled rice, non-parboiled. The method is applicable to rice with an amylose mass fraction higher than 5 %.
This document can also be used for husked rice, maize, millet and other cereals if the extension of this scope has been validated by the user.
NOTE Amylose values determined with this document can…
Smart cities - City service continuity against disasters - The role of the electrical supply
IEC 63152:2020 establishes concepts and gives guidelines to help sustain a variety of city services on the occasion of a disaster from the perspective of providing electricity. It outlines the basic concepts on how multiple city services can cooperate and continue by electricity continuity plan(s) and electricity continuity system(s). It also specifies methods and means to establish these.<br…
