This document defines basic terms relating to the work of ISO/TC 180. The committee covers standardization in the field of the measurement of solar radiation and solar energy utilization in space and water heating, cooling, industrial process heating and air conditioning. Consequently, the vocabulary within this document is focussed on definitions relating to those measurement and utilisation…
Information technology - JPEG XL image coding system - Part 1: Core coding system
This document defines a set of compression methods for coding one or more images of bi-level, continuous-tone greyscale, or continuous-tone colour, or multichannel digital samples.
This document:
— specifies decoding processes for converting compressed image data to reconstructed image data;
— specifies a codestream syntax containing information for interpreting the compressed image data…

Mechanical vibration — Laboratory method for evaluating vehicle seat vibration — Part 2: Application...
This document defines specifications covering laboratory tests for seats designed for passengers and crew in railway tractive and trailer vehicles.
It concerns tri-axial rectilinear vibration within the frequency range 0,5Â Hz to 50Â Hz. It specifies the input test vibration to be used at seat testing.
This document makes it possible to characterize, in the form of frequency response functions, the…
Information technology - JPEG XS low-latency lightweight image coding system - Part 1: Core coding s...
This document defines the syntax and an accompanying decompression process that is capable to represent continuous-tone grey-scale, or continuous-tone colour digital images without visual loss at moderate compression rates. Typical compression rates are between 2:1 and 6:1 but can also be higher depending on the nature of the image. In particular, the syntax and the decoding process specified in…
Information technology - JPEG XS low-latency lightweight image coding system - Part 2: Profiles and ...
This document defines a number of subsets of the syntax specified in ISO/IEC 21122-1 as profiles. It also defines lower bounds on the throughput in the decoded domain via levels and the encoded domain via sublevels that a conforming decoder implementation shall support. Furthermore, it defines a buffer model to ensure interoperability between implementations in the presence of a latency…
Information technology - JPEG XS low-latency lightweight image coding system - Part 3: Transport and...
This document defines transport and container formats for JPEG XS codestreams as specified in ISO/IEC 21122-1. It defines file formats for working with still image and motion image sequence files on computer platforms and gives guidance on how to embed the codestream in transport streams, allowing internet-based communication.
This document uses already existing specifications for file formats…
Fibre optic sensors - Part 3-2: Acoustic sensing and vibration measurement - Distributed sensing
IEC 61757-3-2:2022 specifies the terminology, characteristic performance parameters, related test and calculation methods, as well as specific test equipment for interrogation units used in distributed fibre optic acoustic sensing and vibration measurement systems. This document refers to the Rayleigh backscatter and phase detection method by phase-sensitive coherent optical time-domain…
