IEC 61439-6:2012 lays down the definitions and states the service conditions, construction requirements, technical characteristics and verification requirements for low voltage BTS (see 3.101) as follows: - BTS for which the rated voltage does not exceed 1 000 V in case of a.c. or 1 500 V in case of d.c.; - BTS intended for use in connection with the generation, transmission, distribution and…

IEC 61754-20-100:2012 covers connectors with protective housings. The housing is defined as variant 4 in IEC 61076-3-106:2006. These connectors use a push-pull coupling mechanism. To connect the fibres inside the housing the LC interface is used as described in IEC 61754-20:2002. The fully assembled variants (connectors) described in this document incorporate fixed and free connectors.

IEC 61754-20-100:2012 couvre les connecteurs avec boîtiers de protection. Le boîtier est défini comme la variante 4 de l’IEC 61076-3-106:2006. Ces connecteurs utilisent un mécanisme d'accouplement pousser-tirer. Pour connecter les fibres à l'intérieur du boîtier, l'interface LC est utilisée comme cela est décrit dans l’IEC 61754-20:2002. Les variantes entièrement assemblées (…

IEC 61535:2009+A1:2012 applies to two up to five wire installation couplers including earth, if provided, with a rated voltage up to and including 500 V a.c. and a rated connecting capacity up to and including 10 mm² for permanent connection in indoor electrical installations. Installation couplers with additional contacts for voltages other than mains voltages are outside the scope of this…

IEC 60862-2:2012 gives practical guidance on the use of SAW filters which are used in telecommunications, measuring equipment, radar systems and consumer products. IEC 60862-1 should be referred to for general information, standard values and test conditions. This part of IEC 60862 includes various kinds of filter configuration, of which the operating frequency range is from approximately 10 MHz…

1.1 Scope This standard specifies uniform methods for testing and evaluating the performance of fittings for use with compressed hydrogen gas and hydrogen rich gas mixtures. It does not address special requirements for liquid and slush hydrogen. This standard applies to hydrogen systems applications to meet current market needs. In this standard, the term “fittings” includes fittings,…
