IEC 61747-4-1:2014(E) describes the essential ratings and characteristics of matrix colour liquid crystal display (LCD) modules. This edition includes the following significant technical changes with respect to the previous edition: Adding the contents of the IEC 61747 series, adding the TFT technical kinds, revising the electrical and optical characteristics in Table 1 and correcting some…

ISO 1656:2014 specifies a macro-method and a semi-micro method for the determination of nitrogen in raw natural rubber and in natural rubber latex using variants of the Kjeldahl process.

ISO 17855-1:2014 establishes a system of designation for polyethylene thermoplastic material, which may be used as the basis for specifications. ISO 17855-1:2014 is applicable to all polyethylene homopolymers and to copolymers of ethylene having a content of other 1-olefinic monomers of less than 50 % (mass fraction) and a content of non-olefinic monomers with functional groups up to a maximum of…

IEC 60793-1-20:2014 establishes uniform requirements for measuring the geometrical characteristics of uncoated optical fibres. The geometry of uncoated optical fibres directly affect splicing, connectorization and cabling and so are fundamental parameters requiring careful specification, quality control, and thus measurement. This second edition cancels and replaces the first edition, published…

IEC 61243-3:2014 is applicable to hand-held two-pole voltage detectors with their accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2/3 Hz and up to 500 Hz, and/or for d.c. voltages not exceeding 1 500 V. Contact electrode extensions are not covered by this standard.…

ISO 13061-1:2014 specifies oven-drying methods for determining the moisture content of wood for physical and mechanical tests on small clear wood specimens.

1 Scope 1.1 This Standard applies to newly produced direct gas-fired crop dryers of the recirculating or non recirculating type hereinafter referred to as “dryers”, whose primary purpose is to provide process heating to dry farm crops. These dryers are used in non-occupied spaces and are constructed of non- combustible materials having input ratings of 12,500,000 Btu/hr (3 663 389 W) or less,…

ISO 16960:2014 specifies a method for the determination of total sulfur in the range from 1 mg/m3 to 200 mg/m3 in pipeline natural gas by oxidative microcoulometry. Natural gas with sulfur contents above 200 mg/m3 can be analysed after dilution with a suitable sulfur-free solvent.

IEC 61196-10:2014 applies to semi-rigid coaxial communication cables with polytetrafluoroethylene (PTFE) dielectric and tubular outer conductor. These cables are intended for use in microwave and wireless equipments or other signal transmission equipments or units at frequencies above 500 MHz. The contents of the corrigendum of February 2016 have been included in this copy.<br /> <br /…
