Measurement procedures for materials used in photovoltaic modules - Part 7-2: Environmental exposure...
IEC TS 62788-7-2:2017(E) defines test procedures to characterize the weatherability of polymeric component materials used in photovoltaic (PV) modules or systems. The methods in this document have been focused on polymeric backsheets and encapsulants, but may be applied to other materials; however, these were not verified as part of the preparation. Exposures in this document are intended for…
Electricity metering data exchange - The DLMS/COSEM suite - Part 6-2: COSEM interface classes
IEC 62056-6-2:2017 specifies a model of a meter as it is seen through its communication interface(s). Generic building blocks are defined using object-oriented methods, in the form of interface classes to model meters from simple up to very complex functionality. Annexes A to F (informative) provide additional information related to some interface classes. This third edition cancels and replaces…

L'IEC 62056-6-2:2017 spécifie un modèle de compteur tel qu'il est vu à travers son/ses interface(s) de communication. Des blocs génériques de base sont définis à l'aide de méthodes orientées objet, sous la forme de classes d'interfaces pour modéliser les compteurs à partir d'une fonctionnalité simple jusqu'à une fonctionnalité très complexe. L'Annexe A à l'…
Terrestrial photovoltaic (PV) systems - Guidelines for effective quality assurance in PV systems ins...
IEC TS 63049:2017(E) provides the minimum activities deemed necessary to implement an effective quality assurance program for the managing and reducing of risk in the installation and operation of photovoltaic (PV) systems. This document defines requirements for certifying that an entity has and uses a quality assurance program to prevent, or reduce errors and learns from any new errors in…
Fire detection and alarm systems — Part 18: Input/output devices
ISO 7240-18:2017 specifies requirements, test methods and performance criteria for input/output devices connected to a transmission path of a fire detection and alarm system used to receive and/or transmit signals to or from the transmission path, necessary for the operation of the fire detection and fire alarm system and/or fire protection system.
An input/output device can be a physically…
ISO 25178-71:2017 defines Type S1 and Type S2 software measurement standards (etalons) for verifying the software of measuring instruments. It also defines the file format of Type S1 software measurement standards for the calibration of instruments for the measurement of surface texture by the areal method as defined in the areal surface texture chain of standards, chain link G.
