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…

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…

This document specifies two methods for determination of the total moisture of brown coals and lignites using an indirect gravimetric single-stage method and a two-stage method.

This document provides guidance and requirements for the maintenance and the use of triaryl phosphate esters as fire-resistant fluids for turbine control, other hydraulic systems in power generation and fire-resistant turbine fluids. This document is applicable to fluids under the HFDR category defined in ISO 6743-4 and under the TCD, TSD and TGD categories defined in ISO 6743-5.

This document specifies two test methods for the determination of water absorption resistance of rubber– or plastics-coated fabrics: —     Method A: Using red ink, which is applied to coated fabric where water absorption phenomenon can be visually observed; —     Method B: Using a water detection test paper.

Le présent document fournit des recommandations et des exigences pour la maintenance et l’utilisation de fluides difficilement inflammables à base de phosphates de tris(aryle) utilisés comme fluides de régulation de turbines ou dans les autres systèmes hydrauliques pour la production d’énergie, ainsi qu’aux fluides difficilement inflammables pour turbines. Ce document est applicable aux fluides…

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 provides information on how electrical designers determine the allowable limit of electric wire in space condition. This document provides the basis of the allowable wire current and its derated value in published technical standards. This document also provides the results of comparing the derated wire current values depending on the number of bundled wires, wire type and…

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…
