This standard is intended for use when the run-out accuracy of the moving parts of electron beam welding machines complying with EN ISO 14744-1 is to be measured in connection with an acceptance inspection. It provides information on the procedure and apparatus to be used for making the measurements. Given the great variety of electron beam welding machines, the scope of measurements required for…

Applies to lampholders with Edison thread E14, E27 and E40, designed for connection to the supply of lamps and semi-luminaires only. Also applies to: -switched-lampholders for use in a.c. circuits only, where the working voltage does not exceed 250 V r.m.s; -lampholders with Edison thread E5 designed for connection to the supply mains of series connected lamps, with a working voltage not…

Applies to three-phase and single-phase transformers including autotransformers. Defines the rating and connection symbols. Gives certain specifications for transformers having a tapped winding. Defines information which shall be marked on the rating plate and the tests to be conducted. Supersedes IEC 60076-1(1976) and IEC 60076-4 (1976). The contents of the corrigendum of June 1997 have been…

This International Standard defines the signalling procedures and protocol for the purpose of circuit-switched Call Control at the Q-reference point between Private Integrated Network Exchanges (PINXs) connected together within a Private Integrated Services Network (PISN). The Q reference point is defined in ISO/IEC 11579-1. This International Standard is based upon that described in ITU-T…

This standard is divided into five sections, each dealing with a specific example of standardized fuse for use by authorized persons: Section I: Fuses with fuse-links with blade contacts. Section II: Fuses with fuse-links for bolted connections. Section III: Fuses with fuse-links having cylindrical contact caps. Section IV: Fuses with fuse-links with offset blade contacts. Section V: Fuses with…

This International Standard specifies the service description and control aspects, including functional capabilities and information flows, of standardised circuit-mode bearer services which may be supported by a Private Integrated Services Network (PISN). This International Standard includes the following basic services: _ Circuit-mode 64 kbit/s unrestricted 8 kHz structured bearer service…

This part of ISO 10333 specifies requirements, test methods, instructions for use and maintenance, marking, labelling and packaging, as appropriate, for lanyards and energy absorbers. Lanyards and energy absorbers are used together as a connecting subsystem in personal fall-arrest systems (PFAS) which will be specified in a future International Standard (see ISO 10333-6 in the Bibliography). Two…
