Prosthetics — Testing of ankle-foot devices and foot units — Requirements and test methods
This document primarily specifies a cyclic test procedure for ankle-foot devices and foot units of external lower limb prostheses, these differ in the potential to realistically simulate those loading conditions of the complete stance phase of walking from heel strike to toe-off which is relevant to the verification of performance requirements such as strength, durability and service life.

Electrical relays - Tests and measurements - Part 15: Robustness of terminals
IEC 63522-15:2024 is used for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combination of these) and evaluates their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
This document defines a standard test method that applies defined loads to relay terminals…
Electrical relays - Tests and measurements - Part 48: Contact failure rate test
IEC 63522-48:2024 is used for for testing electromechanical elementary relays (electromechanical relays, reed relays, reed contacts, reed switches and technology combinations of these) and for evaluating their ability to perform under expected conditions of transportation, storage and all aspects of operational use.
This document defines a standard test method for contact failure rate test of…
Railway applications - Compatibility between rolling stock and train detection systems
IEC 62427:2024 describes a process to demonstrate compatibility between rolling stock (RST) and train detection systems (TDS). It describes the characterization of train detection systems, rolling stock and traction power supply systems.
It is worth noting that the demonstration of technical compatibility between the rolling stock and infrastructure with respect to physical dimensions is not…
Welding — Best practices for specification and measurement of ferrite in stainless steel weld metal
This document describes best practices, based on the experience of experts, for setting appropriate requirements, in specifications and other standards and contract documents, on ferrite content of nominally austenitic or duplex ferritic-austenitic stainless steel weld metals. It also describes a best practice on measurement and measurement reproducibility, and deals with outliers in measurement…
Buy-Ship-Pay reference data model — Part 1: Business requirements specification (BRS)
The scope and limitations of the business processes described in this document have been developed to enable the application of the Buy-Ship-Pay business standard for implementations of national, regional, trade sector or modal specific cross-border scenarios.
NOTE Only the high-level process descriptions are referenced in this document in order that the detailed process analysis of…
Plastics — Determination of the viscosity of polymers in dilute solution using capillary viscometers...
This document specifies the general conditions for the determination of the reduced viscosity, intrinsic viscosity and K‑value of organic polymers in dilute solution. It specifies the standard parameters that are applied to viscosity measurement.
This document is applicable to develop standards for measuring the viscosities in solution of individual types of polymer. It is also applicable to…
Plastics — Marine biodegradation testing — Preparation of optimized intertidal seawater and sediment
This document specifies procedures for preparing seawater and sediments used in test methods to assess the biodegradation of plastic materials in the marine environment. The screened sediment and sediment-rinsed seawater are prepared to sustain aerobic testing at laboratory scale. The described method is designed to separate sediment-rinsed seawater and sand-gravel sediments from intertidal…
Electronic fee collection — Support for traffic management
This document identifies the architecture of a toll system environment in which a toll charger (TC) can act to support traffic management with the use of a tariff scheme.
This document defines:
— the architecture relevant to the scope of this document;
— a standard framework and data flow model;
— an exchange of information between a TC and a road and traffic manager (RTM), e.g.:
— …
Supplementary requirements for intelligent assemblies
IEC TS 63290:2024 provides additional requirements for assemblies in accordance with the product standards of the IEC 61439 series (Part 2 onwards) that incorporate digital functions and communication, in addition to the conventional electromechanical features of assemblies to reflect what is defined within this document as intelligence. It specifies the definitions, service conditions,…
