Information technology — Fibre Distributed Data Interface (FDDI) — Part 25: Abstract test suite for ...
This part of ISO/IEC 9314 contains the Abstract Test Suites for the Fiber Distributed Data Interface
(FDDI) token ring Station Management (SMT) layer protocol. The SMT Protocol is extensive and very
complex. In the development process, the protocol was broken into six separate areas. Those areas
dealt with Physical Connection Management (PCM), Entity Coordination Management (ECM) Ring
Management…

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…
Thyristor valves for high voltage direct current (HVDC) power transmission - Part 1: Electrical test...
Applies to thyristor valves with metal oxide surge arresters
directly connected between the valve terminals, for use in a line
commuted commutated converter for high voltage d.c. power
transmission or as part of a back-to-back link. Retricted to
electrical type and production tests. Tests are based on air
insulated valves.
Valves à thyristors pour le transport d'énergie en courant continu à haute tension (CCHT) - Par...
S'applique aux valves à thyristors équipées de parafoudres à oxyde
métallique directement connectés entre les bornes des valves, qui
sont destinées à être utilisées au niveau d'un convertisseur commuté par le réseau pour le transport d'énergie en courant continu à haute tension ou dans une liaison en opposition. Limitée aux essais de type électrique et de série. Les essais sont…
