Information technology — Coded representation of immersive media — Part 3: Versatile video coding
This document specifies a video coding technology known as versatile video coding (VVC), comprising a video coding technology with a compression capability that is substantially beyond that of the prior generations of such standards and with sufficient versatility for effective use in a broad range of applications.
Only the syntax format, semantics, and associated decoding process requirements…
Leather — Chemical determination of formaldehyde content — Part 1: Method using high-performance liq...
This document specifies a method for the determination of free and released formaldehyde in leathers. This method, based on high-performance liquid chromatography (HPLC), is selective and not sensitive to coloured extracts and is intended to be used for precise quantification of formaldehyde.
The formaldehyde content is taken to be the quantity of free formaldehyde and formaldehyde extracted…

Optical fibre cables - Shrinkage effects on cable and cable element end termination - Guidance
IEC TR 62959:2021 which is a Technical Report, provides information on cable shrinkage characterisation of optical fibre cables that consist of standard glass optical fibres for telecommunication application. The characterisation is directed to the effects of cable shrinkage or cable element shrinkage on the termination of cables. Shrinkage can or cannot be a concern depending on the method of…
Fire resistance tests — Door and shutter assemblies — Part 4: Linear joint fire seal materials used ...
This document specifies a standard test methodology and resulting field of direct application which are applicable to linear joint fire seal materials used to seal around fire door sets which have been tested in accordance with ISO 3008‑1.
The test methodology described in this document uses a smaller-scale fire resistance furnace than that prescribed in ISO 3008‑1.
Thermocouples - Part 3: Extension and compensating cables - Tolerances and identification system
IEC 60584-3:2021 It is necessary for thermocouple temperature measurement that the electro-motive force (abbreviated as e.m.f. hereafter) of the thermocouple circuit is precisely measured by a measuring instrument. A thermocouple is electrically connected to the instrument by a proper pair of electric cables. IEC 60584-3:2021 standardizes these cables. It specifies identification and…
Ships and marine technology — Pressure-vacuum valves for cargo tanks and devices to prevent the pass...
This document is applicable to pressure-vacuum valves and to devices to prevent the passage of flame, both protecting cargo tanks, that can be subject to explosive gas/vapour and/or to gas/vapour pressure or vacuum beyond the design parameters of the system/tank. It specifies the minimum requirements for performance and testing. It also specifies design and in-service performance criteria,…
