IEC 62271-102:2001+A1:2011 applies to alternating current disconnectors and earthing switches, designed for indoor and outdoor enclosed and open terminal installations for voltages above 1 000 V and for service frequencies up to and including 60 Hz. The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. A vertical line in the…

ISO 2919:2012 establishes a classification system for sealed radioactive sources that is based on test performance and specifies general requirements, performance tests, production tests, marking and certification. It provides a set of tests by which manufacturers of sealed radioactive sources can evaluate the safety of their products in use and users of such sources can select types which are…

ISO 12855:2011 specifies the interfaces between electronic fee collection (EFC) systems for vehicle related transport services, e.g. road user charging, parking and access control; it does not cover interfaces for EFC systems for public transport; an EFC system can include any EFC system, e.g. also systems automatically reading licence plate numbers of vehicles passing a toll point; an exchange…

IEC 60598-2-13:2006+A1:2011 specifies requirements for ground recessed luminaires incorporating electric light sources for operation from supply voltages up to 1 000 V, for indoor or outdoor use, e.g. in gardens, yards, carriageways, parking lots, cycleways, footways, pedestrian areas, swimming pools areas outside zones for SELV, nurseries and similar applications. The technical content is…

IEC 61196-8-1:2012 is part of the IEC 61196 series and applies to coaxial communications cables described in IEC 61196-8. It specifies the requirements for semi-flexible radio frequency and coaxial cables with polytetrafluoroethylene (PTFE) dielectric. These cables are for use in microwave and wireless equipment or other signal transmission equipment or units at frequencies from 500 MHz up to 18…

IEC 60432-1:1999+A1:2005+A2:2011 specifies the safety and interchangeability requirements of tungsten filament incandescent lamps for general lighting service having: - rated wattage up to and including 200 W; - rated voltage of 50 V to 250 V inclusive; - bulbs of the A, B, C, G, M, P, PS, PAR or R shapes* , or other bulb shapes where the lamps are intended to serve the same purpose as lamps…

This International Standard specifies a method for direct extraction of DNA from soil samples to analyse the global structure and the abundance of soil bacterial communities using PCR-based technologies. This method is mainly dedicated to agricultural and forest soils. This method can possibly not be suitable for soils rich in organic matter (e.g. peat soils) or soils heavily polluted with…

1 Scope 1.1 The purpose of this Standard is to specify pool pump performance measurements that will facilitate the selection of the most efficient models for performing the combined functions of filtration and pool cleaning. 1.2 This Standard applies to energy performance of centrifugal pump units for the purpose of circulating and filtering water in residential permanently installed…

1 Scope 1.1 General This Standard specifies design, testing, marking, and information requirements for use of full body harnesses. Full body harnesses are intended for use as body supports in personal fall arrest systems and in other work situations that involve the risk of falling. 1.2 Exclusions This Standard does not cover full body harnesses for use in recreational situations such…

1.1 This Standard specifies the requirements for stay in place, modular expanded polystyrene (EPS) Insulating Concrete Form (ICF) units. Once filled with concrete, the ICF units remain in place as the thermal insulation for the resulting cast-in-place concrete wall of uniform cross-section and thickness. 1.2 The requirements of this Standard apply to ICFs that act as permanent formwork for cast-…
