IEC TS 62257-9-5:2024 provides support and strategies for institutions involved in rural electrification projects. It documents technical approaches for designing, building, testing, and maintaining off-grid renewable energy and hybrid systems with AC nominal voltage below 500 V, DC nominal voltage below 750 V and nominal power below 100 kVA. The purpose of this document is to specify laboratory…

This document provides an overview of the validation of air quality measurement methods in the standardization process. This document deals with robustness testing and interlaboratory testing as the two main steps of partial and full validation. It applies to the different inter-related elements of air quality measurement methods, covering e.g. sampling, sample preparation, storage and…

This document identifies specialized use cases related to the information exchange between clinical laboratories and portable polymerase chain reaction (PCR) devices designed for real-time testing to diagnose infectious diseases. This document introduces the portable PCR devices for point-of-care testing (POCT). Characteristic and differentiated use cases of these devices are listed separately…

This document specifies a laboratory test method for determining the water impermeability of textile floor coverings. This document does not apply to the characterization of a wall-to-wall installation of textile floor covering tiles.

This document specifies the principles, reagents and materials, test apparatus, test methods, evaluation of results and requirements for test reports using pilot tests for industrial cooling water systems. This document specifies a method to evaluate the performance of treatment programmes for open recirculating cooling water systems. It is based primarily on laboratory testing, but the heat…

This document specifies methods for exposing specimens to open-flame carbon-arc lamps in the presence of moisture to reproduce the weathering effects that occur when materials are exposed in actual end-use environments to global solar radiation, or to window-glass filtered solar radiation. The specimens are exposed to filtered open-flame carbon-arc light under controlled environmental conditions…

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…

This document establishes requirements for assuring quality, safety, performance and documentation of laboratory-developed tests (LDTs) as per their intended use for the diagnosis, prognosis, monitoring, prevention or treatment of medical conditions. It outlines the general principles and assessment criteria by which an LDT shall be designed, developed, characterized, manufactured, validated (…
