Information technology - Coded representation of immersive media - Part 18: Carriage of geometry-bas...
This document specifies a media format that enables the storage and delivery of geometry-based point cloud compression data. The geometry-based point cloud compression data can be timed or non-timed. It supports flexible extraction of geometry-based point cloud compression data at delivery or decoding time.
Information technology - Criteria for concept systems
This document provides the criteria for effective concept systems. It provides the requirements for components, formation, representations, structural levels and management of concept systems. Concept systems are used in the description of semantics of data in ISO/IEC 11179 standards.

Le présent document spécifie une méthode de détermination de la diffusivité thermique d’un disque plein mince en plastique suivant la direction de l’épaisseur par la méthode flash lumineux. Cette méthode est fondée sur le mesurage de l’élévation de température sur la face arrière d’une éprouvette sous forme de disque mince due à une courte impulsion énergétique sur la face avant.
La méthode est…
Ergonomics of the thermal environment — Management of working conditions in hot environments
This document adopts an approach where actions, particularly control measures and medical supervision, are specified as a function of the class of severity of the potential effects. It provides instructions for appropriate management practices for hot workplaces and describes:
— a procedure for managing work in hot environments;
— guidelines on how to apply the different International…
