This document specifies methods for testing and characterizing the performance of air-to-air heat/energy exchangers when used as devices to transfer heat or heat and water vapor between two airstreams used in ventilation systems. It also specifies methods to characterize the performance of exchangers for use in calculation of the energy performance of buildings. This document is applicable to…

This document specifies the syntax, semantics and decoding for visual volumetric media using video‑based coding methods. This document also specifies processes that can be needed for reconstruction of visual volumetric media, which can also include additional processes such as post‑decoding, pre-reconstruction, post‑reconstruction and adaptation.

This document introduces the effects of population demographics on biometric functions. It: — establishes terms and definitions relevant to the study of demographic factors in biometric recognition system performance; — identifies areas where biometric systems can exhibit different performances based on different demographic factors of the individuals submitting the biometric samples; —…

This document specifies test procedures for the acquisition and presentation of multipoint data which demonstrate the behaviour of plastics under the following environments: —    prolonged exposure to heat; —    liquid chemicals; —    environmental stress cracking under a constant tensile stress; —    artificial weathering. The tests are listed in order of increasing severity of the environment.…

Le présent document spécifie les modes opératoires d’essai en vue de l’acquisition et de la présentation de données multiples qui démontrent le comportement des plastiques dans les environnements suivants : —    exposition prolongée à la chaleur ; —    produits chimiques liquides ; —    fissuration dans un environnement donné sous contrainte de traction constante ; —    vieillissement artificiel…
