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…

This document specifies a reference architecture for event-based syndromic surveillance systems for infectious diseases. The system reference architecture addresses architectural components including concepts, data sources, and outputs of syndromic surveillance system. From the perspective of the diagnostic process,[11] this document covers the processes from the symptom-onset stage to the health…

IEC 60436:2025 applies to electric dishwashers for household and similar use that are supplied with hot and/or cold water. The object of this document is to state and define the principal performance characteristics of electric dishwashers for household and similar use and to describe the standard methods of measuring these characteristics. This document is concerned neither with safety nor with…

This document covers the type testing of valve stem seals using a test fixture that is designed and fully defined to be representative of the performance of a valve using similar geometry. This document is applicable to stem seals for multi-turn, linear and quarter turn valves. It is intended to provide comparative type test results confirming the performance of seal manufacturers’ stem seal…

This document, used in conjunction with ISO 834-1, specifies a method for determining the fire resistance of door and shutter assemblies designed primarily for installation within openings incorporated in vertical separating elements, such as: —     hinged and pivoted doors, —     horizontally sliding and vertically sliding doors, including articulated sliding doors and sectional doors, —    …

IEC 62425:2025 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 62425:2025 edition 2.0 and the previous IEC 62425:2007 edition 1.0. Furthermore, comments from IEC TC 9 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content…

IEC 62425:2025 is applicable to safety-related electronic systems (including subsystems and equipment) for railway signalling applications. This document applies to generic systems (i.e. generic products or systems defining a class of applications), as well as to systems for specific applications. The scope of this document, and its relationship with other IEC and CENELEC standards, are shown in…

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…

This document provides guidance for achieving and demonstrating safety of an automated driving system (ADS) integrated in a road vehicle. The approach is based on safety principles derived from worldwide applicable publications and top-level safety objectives. It considers safety by design, verification and validation, and post deployment activities for level 3 and level 4 ADS features defined…

The purpose of this document is to set out the general principles pertaining to the sampling strategy, to the collection and conditioning of samples, to their transport to the laboratory and to the pre-treatment operations to be carried out prior to analysis. It is intended for the use of organisations that implement a sampling programme as well as organisations responsible for collecting samples…
