ISO 407:2004 concerns pin-index yoke-type valve connections for small medical gas cylinders, with a maximum working pressure (filling pressure at 15 °C) of 200 bar. This type of connection is typically used for small cylinders (5 l or below). In some cases, it may be used for larger cylinders. In this latter case, consideration shall be given to the need for valve protection. It specifies: basic…

Describes the principles for the selection, operation, location and coordination of SPDs connected to telecommunication and signalling networks with nominal system voltages up to 1 000 V r.m.s. a.c. and 1 500 V d.c. Also addresses SPDs that incorporate protection for signalling lines and power lines in the same enclosure.

Décrit les principes à utiliser pour le choix, le fonctionnement, la localisation et la coordination des parafoudres connectés aux réseaux de télécommunications et de transmission de signaux sous une tension nominale de réseau jusqu'à 1 000 V efficace en courant alternatif et 1 500 V en courant continu. Aussi les parafoudres qui incorporent la protection pour les lignes de transmission de…

This national standards of Canada is equivalent to international standards CEI/IEC 61000-2-12:2003. 1. Scope and object This part of IEC 61000 is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. It gives compatibility levels for public medium voltage a.c. distribution systems having a…

ISO 17836:2004 defines the procedure for determining the deposition efficiency for a thermal spray process in connection with a spray material and related equipment and auxiliary materials. It is applicable for all thermal spray processes and all wire, rod, cord and powder spray materials. It is essential to apply this International Standard if data concerning the deposition efficiency of a spray…

ISO 6360-2:2004 specifies the code numbers for the shapes of all dental rotary instruments and for several accessories used in connection with these instruments. This three-digit number for shape description forms the third group of three digits in the 15-digit overall number, the principles of which are explained in ISO 6360-1. NOTE In addition to terms for rotary instruments and accessories…

IEC 81714-3:2004 Specifies requirements concerning the classification of connect nodes assigned to graphical symbols, being a representation of functional and product concepts. Due to the strong interrelation between the product and its corresponding graphical representation, identical classification principles are applied for both the classification of connect nodes of products as well as for…

Scope 1.1.1 This Standard applies to ac and dc type portable fuel cell power systems, with a rated output voltage not exceeding 600 V, for commercial, industrial, and residential indoor and outdoor use in non-hazardous locations, in accordance with the Rules of the National Electric Code, ANSI/NFPA 70. 1.1.2 This Standard does not apply to portable fuel cell power systems that are a.…

IEC 60384-14-2:2004 forms the basis for a uniform procedure for a common International Safety Mark. It implements the approval schedule for safety tests in IEC 60384-14, requires a declaration of design for parameters relevant to safety and prescribes conformance tests to be conducted on every lot prior to its release and requalification tests depending on changes to the declared design. <br…
