IEC 60335-2-69:2012(E) deals with the safety of electrical motor-operated vacuum cleaners, including back-pack vacuum cleaners, and dust extractors, for wet suction, dry suction, or wet and dry suction, intended for commercial indoor or outdoor use with or without attachments. It also deals with the safety of centrally-sited vacuum cleaners, excluding the installation of the system. They are not…

ISO/PAS 17208-1:2012 describes the general measurement systems, procedures and methodologies to be used to measure underwater sound pressure levels from ships at a prescribed operating condition. It presents a methodology for the reporting of one-third-octave band sound pressure levels. The resulting quantities are the sound pressure levels normalized to a distance of 1 m. The underwater sound…

ISO 8503-2:2012 describes a visual and tactile method for assessing the grade of the profile which is produced by one of the abrasive blast-cleaning procedures described in ISO 8504‑2. The method uses ISO surface profile comparators for assessing, on site, the roughness of surfaces before the application of paint or other protective treatments. The method is applicable to steel surfaces which…

L'ISO 8503-2:2012 décrit une méthode visuelle et tactile destinée à évaluer le profil d'une surface préparée par l'une des méthodes par projection d'abrasif décrites dans l'ISO 8504-2. La méthode prévoit l'utilisation de comparateurs viso-tactiles ISO pour évaluer, sur site, la rugosité des surfaces avant l'application de peintures ou d'autres traitements…
