This document specifies two methods for measuring the stiffness and one method for the determination of the flexibility of rubber and plastics hoses and tubing when they are bent to a specific radius at sub-ambient temperatures. Method A is suitable for non-collapsible rubber and plastics hoses and tubing with a bore of up to and including 25 mm. This method provides a means of measuring the…

This document describes a laboratory test method, using an IGT1-type or a prüfbau2-type printability tester, for the preparation of specimens to evaluate the absorption rate of an ink on a substrate in offset lithography by setting-off the printed surface to an unprinted surface. This method describes testing with an amount of ink simulating either single colour or multi-colour printing. The…

IEC TR 63250:2021 deals with the determination of repeatability and reproducibility of test methods used for assessing the performance characteristics of household and similar electrical appliances. It also provides guidance for carrying out round robin tests (RRT). It also specifies the uncertainty reporting of measurements of household and similar electrical appliances. It describes methods…

This document specifies a method, by measuring the amount of carbon dioxide evolved, for the determination of the degree of aerobic biodegradability of plastic materials, including those containing formulation additives. The test material is exposed in a synthetic medium under standardized laboratory conditions to an inoculum from activated sludge under aerobic conditions. The conditions used in…

This document specifies test methods for the measurement of the physical degradation of samples made with plastics materials when exposed to marine environmental matrices under aerobic conditions at laboratory scale. This document is not suitable for the assessment of degradation caused by heat (thermo-degradation) or light exposure (photo-degradation).

IEC 62053-41:2021 applies only to static watt-hour meters of accuracy classes 0,5 and 1 for the measurement of DC electrical energy in DC systems, 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 with two poles where one of the poles is connected to earth and with voltage…

1.1 General This Standard specifies requirements for the packaging, collection, handling, storage, and on-site treatment and disposal of health care waste materials. 1.2 Application 1.2.1 General This Standard applies to health care and veterinary-related waste, and health care-related waste generated from traditional health care settings, public settings, and personal service settings,…

This document specifies a laboratory test procedure for determining the electrical resistance, in wet conditions, between the running rails provided by a fastening system fitted to a steel or concrete sleeper, bearer or element of ballastless track. It is also applicable to embedded rail. This test procedure applies to a complete fastening assembly. It is relevant to signalling currents, not to…

This document specifies a test method for the determination of iron-55 (55Fe) activity concentration in samples of all types of water using liquid scintillation counting (LSC). Using currently available liquid scintillation counters, this test method can measure the 55Fe activity concentrations in the range from the limit of detection up to 120 mBq l-1. These values can be achieved with a…

This document provides guidelines on: — how to express vitamin quantity, — the expression of different molecular forms in appropriate units, — and in some cases, vitamin activity, according to vitamers present or used in food products, in addition to the quantitative content determination obtained from ISO and CEN analytical standards. It provides information to be used as a basis for discussion…
