IEC 61462:2023 applies to composite hollow insulators consisting of a load-bearing insulating tube made of resin-impregnated fibres, a housing (outside the insulating tube) made of elastomeric material (for example silicone or ethylene-propylene) and metal fixing devices at the ends of the insulating tube (see Figure D.1 and Figure D.2 for examples). The object of this document is to define the…

L'IEC 61462:2023 s’applique aux isolateurs composites creux qui sont constitués d’un tube isolant supportant la charge mécanique constitué de fibres imprégnées de résine, protégé par un revêtement en élastomère (par exemple silicone ou éthylène-propylène) et de pièces métalliques fixées à ses extrémités (voir des exemples à la Figure D.1 et à la Figure D.2). Le présent document a pour objet…

This document specifies the values or options chosen for the test parameters (i.e. the impact energy, specimen dimensions, specimen type, specimen supports and test temperature) for both unnotched and notched specimens, for testing the impact resistance (pendulum method) of thermoplastics pipes of the following materials, in accordance with ISO 9854-1. It applies to pipes made of unplasticized…

This document specifies a method for the quantitative determination of monomeric diisocyanate content in coating materials, adhesives and other liquid or pasty materials. This method is suitable for the quantification of the following monomeric diisocyanates: methylene diphenyl diisocyanate (MDI, 2,4’-MDI and 4,4’-MDI), toluene diisocyanate (TDI, 2,6-TDI, 2,4-TDI), (cis/trans) isophorone…

This document specifies the minimum requirements for dynamic positioning (DP) systems on large yachts intended for recreational use (i.e. not mission critical, short duration, mild weather). This document provides minimum requirements for equipment, as well as a calculation method to quantify the DP stationkeeping capability and guidance on testing and personnel requirements.
