Information technology — Telecommunications and information exchange between systems — Use of X.25 t...
For a protocol to support the CONS, there must be a mapping between the abstract primitives and parameters of the CONS and the real elements of the protocol. For the X.25 Packet Layer Protocol (PLP), the main body of this standard provides such a mapping for the X.25/PLP-1984 using Virtual Calls. Also provides a mapping of the CONS primitives and parameters to the X.25/PLP-1980 plus an SNDCP.…
Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques - Section 1: Overvi...
Considers immunity tests for electric and/or electronic equipment (apparatus and systems) in its electromagnetic environment. Both conducted and radiated phenomena are considered including immunity tests for equipment connected to power, control and communication networks. Replaces IEC 60801-1 (1984-11).
Compatibilité électromagnétique (CEM) - Partie 4: Techniques d'essai et de mesure - Section 1: ...
Concerne les essais d'immunité de matériel (appareils et systèmes) électriques et/ou électroniques, dans leur environnement électromagnétique (perturbations conduites et rayonnées). Concerne également les phénomènes conduits et rayonnés en incluant les essais d'immunité des matériels connectés aux réseaux électriques de puissance, de commande et de communication. Remplace la CEI 60801-1…
Road vehicles — Screened and waterproof spark-plugs and their connections — Types 1A and 1B
Specifies the essential dimensional characteristics of a spark-plug type used with spark ignition engines. Tabulates major, pitch, and minor diameters for plug thread and connector thread. A figure illustrates shapes and reference quantities of concern.
Hydraulic fluid power — Identification of valve ports, subplates, control devices and solenoids
Specifies rules for the identification. Applies in particular to valves which will be developed in future with two and three ports, where today's practice of marking valve ports is different. The identification rules apply to those ports which provide the connection between two valves or between a valve and a pipe.
Aerospace — Couplings, threaded and sealed, for fluid systems — Dimensions
Establishes a system for sealing the port connection of couplings. Specifies dimensions to achieve interchangeability of the port connection, the fitting end and a seal. The seal may be a standard O-ring or a special ring.
1. Scope
1.1
This Standard applies to polyethylene pipe, tubing, and fittings for use in gas
mains and services, including gathering, transmission, and distribution
applications, that carry fuel gases containing not more than 1% aromatic
hydrocarbons.
1.2
This Standard also applies to all types of fittings and connections used in a
plastic gas pipe system including plastic-to-metal…
