IEC TR 60893-4:2014+A1:2017 serves as a technical report and presents tables of typical values for properties that are not studied and not given in Table 5 of IEC 60893-3-2:2003/AMD1:2011, IEC 60893-3-3:2003/AMD1:2011, IEC 60893-3-4:2003/AMD1:2012, IEC 60893-3-5:2003/AMD1:2009, IEC 60893-3-6:2003/AMD1:2009, IEC 60893-3-7:2003/AMD1:2009. The purpose of these typical values is to give general…
Low voltage direct current (LVDC) is a disruptive technology that fundamentally accelerates energy access and improves energy efficiency. LVDC applications are many and varied, and can be applied in every country in the world.
In developed economies, the main drivers for the use of LVDC are the improvement of energy efficiency and power quality as well as the conversion to renewable energy…
Qualité du sol — Détermination de la masse volumique des particules
ISO 11508:2017 spécifie deux méthodes permettant de déterminer la masse volumique des particules qui constituent les sols, à partir de la masse et du volume de ces dernières.
La première méthode (4.1) est utilisable pour la terre fine (de diamètre <2 mm), et la seconde méthode (4.2) est utilisable pour les graviers et cailloux (de diamètre >2 mm) poreux ou non poreux.
La masse volumique des…
Information technology — Open Virtualization Format (OVF) specification
The Open Virtualization Format (OVF) Specification describes an open, secure, efficient and
extensible format for the packaging and distribution of software to be run in virtual systems.
The OVF package enables the authoring of portable virtual systems and the transport of virtual
systems between virtualization platforms. This version of the specification (2.1) is intended to allow
OVF 1.x tools…
ISO 11508:2017 specifies two methods for the determination of particle density of soils calculated from the mass and the volume of soil particles.
The first method (4.1) is applicable to fine soil (<2 mm diameter) and the second method (4.2) is applicable to both porous and nonporous gravel and stones (>2 mm diameter).
The particle density can be used for the calculation of the proportion…
ISO/TS 17444-2:2017 defines the Examination Framework for the measurement of charging performance metrics defined in ISO/TS 17444‑1 to be used during Evaluation and/or on-going Monitoring.
It specifies a method for the specification and documentation of a Specific Examination Framework which can be used by the responsible entity to evaluate charging performance for a particular information…

Information technology - Biometric sample quality - Part 4: Finger image data
ISO/IEC 29794-4:2017 establishes
- terms and definitions for quantifying finger image quality,
- methods used to quantify the quality of finger images, and
- standardized encoding of finger image quality,
for finger images at 196,85 px/cm spatial sampling rate scanned or captured using optical sensors with capture dimension (width, height) of at least 1,27 cm × 1,651 cm.
Non-destructive testing of welds — Ultrasonic testing — Testing of welds in austenitic steels and ni...
ISO 22825:2017 specifies the approach to be followed when developing procedures for the ultrasonic testing of the following welds:
- welds in stainless steels;
- welds in nickel-based alloys;
- welds in duplex steels;
- dissimilar metal welds;
- austenitic welds.
The purposes of the testing can be very different, for example:
- for the assessment of quality level (…
