Scope 1.1 This procedure defines the long-term thermal resistance (LTTR) of a foam product as the value measured after 5-year storage in a laboratory environment and provides means for its prediction based on an accelerated laboratory test. 1.2 This procedure, based on ASTM standard test methods ASTM C1303 and ASTM C518, can be applied to a wide range of preformed as well as field…

Domaine d’application 1.1 Cette procédure définit la résistance thermique à long terme (RTLT) d’un produit de mousse comme étant la valeur mesuré après 5 ans d’entreposage dans un environnement de laboratoire et fournit des moyens de prédiction basés sur un essai accéléré en laboratoire. 1.2 Cette procédure, basée sur les méthodes d’essai normalisées ASTM ASTM C1303 et ASTM C518, peut être…

IEC TR 61857-2:2025 gives guidelines to identify the appropriate test method for the evaluation of a proposed electrical insulation system (EIS). Some of the standards evaluate the EIS using one stress factor which is thermal. Other standards evaluate the thermal stress factor with adjustments to the conditioning applied prior to the diagnostic testing to simulate applications in air. A third…

IEC 63455:2025 specifies the 4b/10b line code with error correction for dependable multimedia data transmission, especially for real-time communications even in noisy environments, such as IoT devices, wearable devices, sensor networks, robotics, and spacecraft. This document corresponds to the functions specified in layer 1 to layer 2 of the OSI reference model (ISO/IEC 7498). This document…

IEC 63455:2025 spécifie le code en ligne 4b/10b avec correction d’erreurs pour la transmission fiable de données multimédias, en particulier pour les communications en temps réel, même dans des environnements bruyants, tels que les dispositifs IdO, les dispositifs portatifs, les réseaux de capteurs, la robotique et les engins spatiaux. Il correspond aux fonctions spécifiées dans les couches 1 à 2…

IEC 60684-3-282:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60684-3-282:2025 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, stress control…

IEC 60684-3-282:2025 gives the requirements for two types of heat-shrinkable, polyolefin sleeving, stress control, not flame retarded, with a nominal shrink ratio up to 3:1. This sleeving has been found suitable for use up to temperatures of 100 °C. Type A: Medium wall Internal diameter up to 65,0 mm typically Type B: Thick wall Internal diameter up to 95,0 mm typically Since these types of…

L'IEC 60684-3-282:2025 donne les exigences relatives à deux types de gaines thermorétractables, en polyoléfine, à contrôle de contrainte, non ignifugées, avec un rapport de rétreint nominal jusqu'à 3:1. Ces gaines se sont révélées être adaptées à une utilisation à des températures allant jusqu’à 100 °C. Type A: Paroi moyenne Diamètre intérieur type jusqu’à 65,0 mm Type B: Paroi…

This document establishes requirements and recommendations for the design format and data content of a drone or UAS remote pilot and remote crew licence, encompassing both visual human-readable features and machine-readable technologies. By establishing a common basis, this document aims to standardize drone or UAS remote pilot and remote crew licence without impeding the efforts of individual…

This document specifies requirements for five types of compact, wire-braid-reinforced hoses and hose assemblies of nominal size from 5 to 76. They are suitable for use with: —     oil-based hydraulic fluids HH, HL, HM, HR and HV as defined in ISO 6743-4 at temperatures ranging from −40 °C to +100 °C; —     water-based fluids HFC, HFAE, HFAS and HFB as defined in ISO 6743-4 at temperatures ranging…
