1.1 Scope 1.1.1 This standard contains safety requirements for material, design, manufacture and testing of gaseous hydrogen hose and hose assemblies. This standard applies to newly manufactured hose and hose assemblies for: • connecting the dispenser to the fueling nozzle, high pressure (class A) • used as part of a vehicle on-board fuel storage system, high pressure (class B) • used as…

1.1 Scope 1.1.1 Equipment included in scope This part of IEC 61010 specifies general safety requirements for the following types of electrical equipment and their accessories, wherever they are intended to be used. a) Electrical test and measurement equipment This is equipment which by electromagnetic means tests, measures, indicates or records one or more electrical or physical quantities…

IEC 60947-3:2008+A1:2012 applies to switches, disconnectors, switch-disconnectors and fuse-combination units to be used in distribution circuits and motor circuits of which the rated voltage does not exceed 1 000 V a.c. or 1 500 V d.c. The manufacturer shall specify the type, ratings and characteristics according to the relevant standard of any incorporated fuses. The technical content is…

1 Scope This International Standard specifies specimen dimensions, testing equipment and the procedure for torsion testing of resistance spot welds with single sheet thicknesses ranging from 0,5 mm to 6,0 mm in steels. It can be used for non-ferrous materials in certain circumstances. The aim of this International Standard is to determine the weld diameter and the failure type of fractured…

This part of ISO 21360 specifies methods for measuring the volume flow rate, base pressure, water vapour tolerance, power consumption, and the lowest start-up temperature of positive displacement vacuum pumps, which discharge gas against atmospheric pressure and with a usual base pressure <10 kPa. In this part of ISO 21360, it is necessary to use the determinations of volume flow rate and base…

IEC 61362:2012 includes relevant technical data necessary to describe hydraulic turbine governing systems and to define their performance. It is aimed at unifying and thus facilitating the selection of relevant parameters in bidding specifications and technical bids. It will also serve as a basis for setting up technical guarantees. The scope of this standard is restricted to the turbine…

IEC 61076-2-101:2012 describes M12 circular connectors typically used for industrial process measurement and control. These connectors consist of fixed and free connectors either rewireable or non-rewireable, with screw-locking. The connectors with glass to metal seal are fixed connectors only which consist of fixed glass to metal sealed styles with rewireable male contacts and are intermateable…

IEC 61754-29:2012 defines the standard interface dimensions for the type BLINK series of connectors.

This International Standard establishes the specifications for the International Standard Collection Identifier (ISCI) as a unique international identification system for each collection, fonds and (archival) series, and part(s) of collections, fonds and series. This International Standard establishes the specifications for the structure of an identifier and promotes the use of the identifier…

1.1 This International Standard specifies a general method for determining the resistance to abrasive wear of plastics under the action of abrasive wheels. It is equally applicable to moulded test specimens, components and finished products. 1.2 The particular test conditions and the method of expressing the results may differ according to the type of material. The test conditions and specific…
