ISO 7730:2005 presents methods for predicting the general thermal sensation and degree of discomfort (thermal dissatisfaction) of people exposed to moderate thermal environments. It enables the analytical determination and interpretation of thermal comfort using calculation of PMV (predicted mean vote) and PPD (predicted percentage of dissatisfied) and local thermal comfort, giving the…

This document defines a test procedure to simulate and evaluate lumbar and cervical spinal disc prostheses wear under adverse impingement conditions.

This International Standard specifies methods for determining the level of particulate contamination in liquids used in hydraulic systems by counting the number of particles deposited on the surface of a membrane filter using an optical microscope. It includes particle counting by two manual methods and image analysis, using either transmitted or incident lighting systems. Particle sizes greater…

This standard specifies a test method for determining the resistance to water leakage and penetration of water resistant clothing in an artificial rainfall by means of a manikin capable of marching motion. It becomes effective for determining the waterproof characteristic in practical use in a rainfall environment with the wearer moving. It is applicable to the testing of waterproof or water…

ISO 13347-2:2004 gives a detailed description of reverberant room methods for the determination of fan sound power levels. It is for use under standardized laboratory conditions and recognises that tests in situ are subject to increased uncertainty. These test procedures are not necessarily appropriate to site test conditions. Acoustic system effects are presently the subject of considerable…

This document specifies the method and criteria for monitoring corrosion states of heat exchange tubes, heat exchange plates, and other components made of stainless steel in industrial cooling water by a combination of polarization resistance and corrosion potential. This document is applicable to the monitoring of the corrosion states of stainless steel in industrial cooling water or similar…

L'ISO 12215-9:2011 définit les chargements et spécifie l'échantillonnage des appendices des bateaux à voiles d'une longueur de coque, LH, mesurée conformément à l'ISO 8666, inférieure ou égale à 24 m. Elle fournit: les contraintes de conception, les éléments structurels à évaluer, les cas de chargement et les charges de conception pour la quille, la dérive et leurs éléments de…
