Information technologies — JPEG systems — Part 5: JPEG universal metadata box format (JUMBF)
This document describes the JPEG universal metadata box format (JUMBF), which provides a universal format to embed any type of metadata in any box-based JPEG file format. This document defines the syntax of the JUMBF box and the mechanism to assign specific content types. In particular, this document specifies XML, JSON, codestream and UUID types. In addition, this document defines the syntax to…

Vulcanized rubber — Determination of free sulfur by gas chromatography (GC) and high performance liq...
This document specifies chromatographic methods for the determination of the inorganic free sulfur (Sx) not consumed during the vulcanization of the rubber. This method is used primarily to compare the free sulfur content in different samples.
NOTE 1 In this document, "free sulfur" is used instead of "inorganic free sulfur".
NOTE 2 The residual curing agent containing…
Systems and software engineering — System of systems (SoS) considerations in life cycle stages of a ...
1.1 Purpose This document provides a set of critical system of systems (SoS) considerations to be addressed at key points in the life cycle of the system of interest (SoI). This document refers to considerations that apply to an SoI that is a constituent system that interacts in an SoS. The considerations and life cycle model align with those which are already defined in ISO/IEC/IEEE 15288 and…
Aluminium oxide primarily used for the production of aluminium — Preparation and storage of test s...
This document describes methods for the sample preparation of smelter-grade aluminium oxide. It covers the reduction of a bulk sample between 1 kg and 20 kg to produce a sample that is suitable for chemical and physical analysis. The reduced sample produced will be representative of the initial bulk sample. The bulk sample is considered to be from one source.
The methods are suitable for dry,…
