IEC 60335-2-30:2009+A1:2016+A2:2021 Deals with the safety of electric room heaters for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. Examples of appliances that are included are: - convection heaters; - fan heaters; - heaters for greenhouses; - liquid-filled radiators; - panel heaters; - radiant…

IEC 61937-2:2021 specifies the digital audio interface to convey non-linear PCM encoded audio bitstreams applying IEC 60958-1 and IEC 60958-3. This document specifies burst-info, which defines content information about the data contained in the burst-payload. IEC 61937-2:2021 cancels and replaces the second edition published in 2007, Amendment 1:2011 and Amendment 2:2018. This edition constitutes…

This document specifies the test methods for discrete polymer fibre for fibre-reinforced cementitious composites (FRCC). This document defines the test methods for discrete polymer fibre, such as diameter, length, tensile strength, initial modulus of elasticity, density, melting point, moisture content and alkaline durability as basic items. These are test methods intended for certification of a…

The ALERT-C protocol is designed to provide mostly event-oriented road end-user information messages. This document specifies the messages which are presented to the user in accordance with a set of general requirements. It defines the message structure and content and its presentation to the end-user. The message management component of this document describes the message management functions…

IEC 61000-4-30:2015+A1:2021 defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method's implementation. This standard addresses…

This document specifies a method for the determination of moisture in a general analysis sample by drying the sample in an oven. This method is suitable for use for general analysis samples in accordance with CEN/TS 15414‑1[3][1]. It is applicable to all solid recovered fuels. If solid recovered fuels contain large amounts of oil-fractions the Karl-Fischer-Method (for example ISO 760) is…

IEC 62841-3-1:2014+A1:2021 applies to transportable table saws with: - a toothed single blade; or - stacked blades that cut a single groove or slot; or - a moulding head cutter intended for cutting wood and analogous materials, plastics and nonferrous metals except magnesium with a saw blade diameter between 105 mm and 315 mm, which hereinafter may simply be referred to as saw or tool. The…

IEC 61800-2:2021 applies to adjustable speed electric AC power drive systems, which include semiconductor power conversion and the means for their control, protection, monitoring, measurement and the AC motors. It applies to adjustable speed electric power drive systems intended to feed AC motors from a BDM or CDM connected to line-to-line voltages up to and including 35 kV AC 50 Hz or 60 Hz and…

1 Scope This document describes the method of determining the total moisture content of a test sample of solid biofuels by drying in an oven and is used when the highest precision is not needed, e.g. for routine production control on site. The method described in ISO 18134 (all parts) is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported…

1 Scope This document is intended to be used in any sector of activity. It specifies: — contents of command-response pairs exchanged at the interface, — means of retrieval of data elements and data objects in the card, — structures and contents of historical bytes to describe operating characteristics of the card, — structures for applications and data in the card, as seen at the interface…
