1 DOMAINE D’APPLICATION 1.1 La présente norme énonce les exigences minimales pour les propriétés et le rendement des matériaux des membranes utilisées pour le confinement secondaire en dessous et autour des réservoirs de stockage de liquides inflammables et de liquides combustibles hors sol. 1.2 Les membranes servant au confinement secondaire sont conçues pour être installées de façon…

IEC 60335-2-72:2012(E) deals with the safety of powered ride-on and powered walk-behind machines intended for commercial indoor or outdoor use for the following applications: - sweeping, - scrubbing, - wet or dry pick-up, - polishing, - application of wax, sealing products and powder based detergents, - shampooing of floors with an artificial surface. Their cleaning motion is more linear than…

ISO 3758:2012 establishes a system of graphic symbols, intended for use in the marking of textile articles, and for providing information on the most severe treatment that does not cause irreversible damage to the article during the textile care process, and specifies the use of these symbols in care labelling. The following domestic treatments are covered: washing, bleaching, drying and ironing…

IEC/PAS 62734:2012(E) defines the OSI layer specifications (e.g., PhL, DL, etc.), security specifications, and management (including network and device configuration) specifications for wireless devices serving application classes 1 through 5 and optionally class 0 for fixed, portable, and moving devices. It addresses the performance needs for periodic monitoring and process control where…

ISO 16810:2012 defines the general principles required for the ultra­sonic examination of industrial products that permit the trans­mis­sion of ultrasound. The specific conditions of application and use of ultrasonic examination, which depend on the type of product examined, are described in documents which could include: a) product standards; b) specifications; c) codes; d) contractual documents…

ISO 16823:2012 specifies the principles of transmis­sion techniques. Transmission techniques can be used for: a) detection of imperfections; b) determination of attenuation. The general principles required for the use of ultrasonic examina­tion of in­dustrial products are described in ISO 16810. The transmission technique is used for examination of flat pro­ducts, e.g. plates and sheets. Further…

ISO 16826:2012 defines the principles for tandem‑ and longitudinal-longitudinal-transverse (LLT) wave‑examination for the detection of discontinuities perpendicular to the surface. The general principles required for the ultrasonic examination of industrial products are described in ISO 16810. A list of symbols and equations is given in ISO 16811. The tandem‑ or LLT‑examination should be used for…
