This International Standard specifies the functional protocol for the support of supplementary services and additional basic call capabilities at the Q-reference point. The Q-reference point exists between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN) and is defined in ISO/IEC 11579-1. The generic functional protocol is…

This International Standard specifies a dynamic test method for mechanical hook-type connections and hook coupling devices, as well as a static test of their keeper plates. It is applicable to hooks meeting the requirements of ISO 6489-1 used on towing vehicles with an unladen mass of up to 10 t. Towing vehicles with a greater unladen mass are nevertheless treated as 10 t towing vehicles,…

This part of IEC 61851 together with part 1 gives the electric vehicle requirements for conductive connection to an a.c. or d.c. supply, for a.c. voltages according to IEC 60038 up to 690 V and for d.c. voltages up to 1 000 V, when the electric vehicle is connected to the supply network. This publication is of high relevance for Smart Grid.

1.1 Scope 1.1.1 This standard applies to newly produced, gas-fired low-intensity infrared heaters and infrared radiant tube heaters (see Part IV, Definitions), hereinafter referred to as heaters or appliances, constructed entirely of new, unused parts and materials with inputs up to and including 400 000 Btu per hour (117.23 kW) per burner: a. For use with natural gas; b. For use…

1.1 Scope 1.1.1 This standard applies to newly produced, gas-fired high-intensity infrared heaters (see Part IV, Definitions), hereinafter referred to as heaters or appliances constructed entirely of new, unused parts and materials: a. For use with natural gas; b. For use with manufactured gas; c. For use with mixed gas; d. For use with liquefied petroleum (propane) gases…

Relates to the immunity requirements, test methods, and range of recommended test levels for equipment to unidirectional surges caused by overvoltages from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment. Establishes…

Relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 9 kHz up to 80 MHz. Equipment not having at least one conducting cable (such as mains supply, signal line or earth connection), which can couple the equipment to the disturbing RF fields is excluded.…
