1. Scope
The scope of this standard is to define the Media Access Control (MAC) Service provided by all IEEE 802®
MACs, and the Internal Sublayer Service (ISS) provided within MAC Bridges, in abstract terms of the
following:
a) Their semantics, primitive actions, and events; and
b) The parameters of, interrelationship between, and valid sequences of these actions and events.
Intelligent transport systems — Cooperative ITS — Using V2I and I2V communications for applications ...
This document defines the message, data structures, and data elements to support exchanges between the roadside equipment and vehicles to address applications to improve safety, mobility and environmental efficiency. In order to verify that the defined messages will satisfy these applications, a systems engineering process has been employed that traces use cases to requirements and requirements…

Information technology — Generic coding of moving pictures and associated audio information — Part 1...
This Recommendation | International Standard specifies the system layer of the coding. It was developed principally to support the combination of the video and audio coding methods defined in Parts 2 and 3 of ISO/IEC 13818. The system layer supports six basic functions:
1) the synchronization of multiple compressed streams on decoding;
2) the interleaving of multiple compressed streams into…

Rapeseed and rapeseed meals — Determination of glucosinolates content — Method using high-performanc...
This document specifies a method for the determination of the individual glucosinolates content in rapeseeds and rapeseed meals using high-performance liquid chromatography with gradient elution.
This method was tested on rapeseeds and rapeseed meals (Brassica rapa, Brassica napus and Brassica juncea) but is applicable to other plant materials, on the condition that the occurring glucosinolates…

IEC 60793-2-10:2019 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 60793-2-10:2019 is applicable to optical fibre sub-categories A1-OM1, A1-OM2, A1-OM3, A1-OM4, A1-OM5, and A1d…
Low-voltage switchgear and controlgear - Part 5-4: Control circuit devices and switching elements - ...
IEC 60947-5-4:2002+A1:2019 applies to separable contacts used in the utilization area considered, such as switching elements for control circuits. This standard takes into consideration two rated voltage areas:
a) above (and including) 10 V (typically 24 V) where contacts are used for switching loads with possible electrical erosion, such as programmable controller inputs;
b) below 10 V (…
