IEC 62053-22:2020 applies only to transformer operated static watt-hour meters of accuracy classes 0,1 S, 0,2 S and 0,5 S for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only. This document applies to electricity metering equipment designed to: • measure and control electrical energy on electrical networks (mains…

IEC 62053-23:2020 applies only to static var-hour meters of accuracy classes 2 and 3 for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. For practical reasons, this document is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.…

IEC 62053-24:2020 applies only to static var-hour meters of accuracy classes 0,5S, 1S, 1, 2 and 3 for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. This document uses a conventional definition of reactive energy where the reactive power and energy is calculated from the fundamental frequency components of the…

This document specifies the validation and verification requirements applicable to a biobank to be able to demonstrate that it operates its processing of biological materials with validated and/or verified methods that are fit for purpose. This document is intended for use in the implementation and validation of processing methods for biological materials. This document covers method validation…

This document provides a laboratory test method to determine the skin-friction of antifouling paints coated on drums. The results of the laboratory-tested friction of painted drums over a certain period of time can be used for screening of antifouling paints and characterizing changes in friction for different antifouling paints, amongst other applications and other purposes depending on the user…

This document specifies a test method to determine the degree and rate of aerobic biodegradation of plastic materials when settled on marine sandy sediment at the interface between seawater and the seafloor, by measuring the evolved carbon dioxide (CO2). This test method can also be applied to other solid materials. This test method is a simulation under laboratory conditions of the habitat found…

This document provides guidance to biobanks on how to implement the quality management, management, and technical requirements of ISO 20387. It expands on aspects of ISO 20387 and provides examples for illustration purposes. The aim of this document is to assist biobanks to address competency of personnel and appropriate quality of biological material and data collections. This document is…

IEC TS 62257-12-1:2020 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 TS 62257-12-1:2020 establishes the framework for creating a product specification for lamps and lighting…

IEC TS 62257-12-1:2020 is available as IEC TS 62257-12-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC TS 62257-12-1:2020 establishes the framework for creating a product specification for lamps and lighting appliances to serve as the basis for evaluating quality for a particular…

This document provides the fundamental principles and guidelines for industrial wastewater treatment technology pilot studies. It does not address laboratory research and development, study or testing of a given technology. It does not cover reuse applications or operations, such as irrigation. This document applies to a wide range of industrial water treatment systems for the purposes of reuse.
