Le présent document spécifie les caractéristiques des robinets en polyamide non plastifié (PA-U) conformément à l’ISO 16486-1, destinés à être enterrés et utilisés pour la distribution de combustibles gazeux. NOTE 1        Pour les besoins du présent document, le terme «combustibles gazeux» inclut par exemple le gaz naturel, le méthane, le butane, le propane, l'hydrogène, le gaz manufacturé…

IEC 60684-3-281:2025 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, semiconductive, with a nominal shrink ratio of 3:1. This sleeving has been found suitable for use up to temperatures of 100 °C. -Type A: Thin wall - Internal diameter up to 195,0 mm typically -Type B: Medium wall - Internal diameter up to 120,0 mm typically This sleeving is normally supplied in…

L'IEC 60684-3-281:2025 donne les exigences relatives à deux types de gaines thermorétractables, en polyoléfine, semiconductrices, dont le rapport de rétreint nominal est égal à 3:1. Ces gaines se sont révélées être adaptées à une utilisation à des températures allant jusqu’à 100 °C. - Type A: Paroi mince - Diamètre intérieur type jusqu’à 195,0 mm - Type B: Paroi moyenne - Diamètre…

IEC 62911:2025 defines procedures for use during or after manufacturing of complete equipment, sub-assemblies or components, complying with IEC 62368-1 and powered by an AC or DC, to detect manufacturing failures and unacceptable tolerances in manufacturing and materials. NOTE 1: Not all the tests defined in this document are necessarily performed at the end product manufacturing location. The…

L'IEC 62911:2025 définit des procédures d'essai destinées à être utilisées en cours ou en fin de fabrication d'appareils complets, de sous-ensembles ou de composants conformes à l'IEC 62368-1 et alimentés par un réseau d’alimentation en courant alternatif ou par un réseau d’alimentation en courant continu, afin de détecter des défaillances de fabrication et des tolérances…

1 Scope 1.1 Inclusions This Standard applies to the construction, materials, performance, and testing of NPS 1-1/4 in (32 mm) and smaller self-acting service-type regulators with overpressure protection devices utilized to control the pressure of gas delivered to a customer’s piping at a delivery pressure of 2 psi (14 kPa) or less. 1.2 Temperature ratings This Standard includes regulators…

1 Scope 1.1 This Standard applies to solid-state circuit breakers (SSCBs) and solid-state hybrid circuit breakers (SSHCBs) using semiconductor switching technology intended for applications where overcurrent protection complies with CSA C22.1. 1.2 This Standard applies to a) solid-state circuit breakers (SSCBs) and switches (SSCSs) with air gap isolation; and b) solid-state hybrid circuit…

1 Scope This part of IEC 61800 specifies requirements for adjustable speed electrical power drive systems (PDS) or their elements, with respect to electrical, thermal, fire, mechanical, energy and other relevant hazards. It does not cover the driven equipment except for interface requirements. It applies to adjustable speed electrical PDS which include the power conversion, basic drive module (…
