Insulated bushings for alternating voltages above 1000 V
IEC 60137:2017 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 60137:2017 specifies the characteristics and tests for insulated bushings.
This standard is applicable to bushings…
Thermal performance of buildings — Heat transfer via the ground — Calculation methods
ISO 13370:2017 provides methods of calculation of heat transfer coefficients and heat flow rates for building elements in thermal contact with the ground, including slab‐on‐ground floors, suspended floors and basements. It applies to building elements, or parts of them, below a horizontal plane in the bounding walls of the building situated
- at the level of the inside floor surface, for slab‐…
Acoustics — Methods for calculating loudness — Part 1: Zwicker method
ISO 532-1:2017 specifies two methods for estimating the loudness and loudness level of sounds as perceived by otologically normal persons under specific listening conditions. The first method is intended for stationary sounds and the second method for arbitrary non-stationary (time-varying) sounds, including stationary sounds as a special case.
The methods can be applied to any sound recorded as…

IEC 60287-3-1:2017 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 60287-3-1:2017 is applicable to the conditions of steady-state operation of cables at all voltages, buried…
Electric cables - Calculation of the current rating - Part 3-1: Operating conditions - Site referenc...
IEC 60287-3-1:2017 is applicable to the conditions of steady-state operation of cables at all voltages, buried directly in the ground, in ducts, troughs or in steel pipes, both with and without partial drying-out of the soil, as well as cables in air. The term "steady state" is intended to mean a continuous constant current (100 % load factor) just sufficient to produce asymptotically…
Nanotechnologies — Plain language explanation of selected terms from the ISO/IEC 80004 series
ISO/TR 18401:2017 is intended to assist stakeholders who are making decisions about the direction, management and application of nanotechnologies to better understand selected key terms and definitions in the ISO/IEC 80004 vocabulary series for nanotechnologies.
Optical circuit boards - Basic test and measurement procedures - Part 2: General guidance for defini...
IEC 62496-2:2017 specifies a method of defining the conditions for measurements of optical characteristics of optical circuit boards. The method comprises the use of code reference look-up tables to identify different critical aspects of the measurement environment. The values extracted from the tables are used to construct a measurement identification code, which, in itself, captures sufficient…

Information technology — Multimedia framework (MPEG-21) — Part 21: Media contract ontology
ISO/IEC 21000-21:2017 specifies an ontology for representing contracts in the Multimedia Framework formed for the transaction of MPEG-21 Digital Items or services related to the MPEG-21 Framework.
Media Contract Ontology (MCO) aims to digitally express agreements made in environments using ISO/IEC 21000. These agreements are contracts for transactions of content packed as Digital Items, as well…
Smart city concept model - Guidance for establishing a model for data interoperability
ISO/IEC 30182:2017 describes, and gives guidance on, a smart city concept model (SCCM) that can provide the basis of interoperability between component systems of a smart city, by aligning the ontologies in use across different sectors. It includes:
- concepts (e.g. ORGANIZATION, PLACE, COMMUNITY, ITEM, METRIC, SERVICE, RESOURCE); and
- relationships between concepts (e.g. ORGANIZATION…
