IEC TR 61400-21-3:2019 provides guidance on principles which can be used as the basis for determining the application, structure and recommendations for the WT harmonic model. For the purpose of this Technical Report, a harmonic model means a model that represents harmonic emissions of different WT types interacting with the connected network. This document is focused on providing technical…

IEC TS 62764-1:2019(E) applies to the assessment of human exposure to low frequency magnetic fields generated by automotive vehicles. For plug-in vehicles, this includes the electric vehicle supply equipment (EVSE) and associated cables provided by the car manufacturer. The scope of this document establishes the measurement procedure for the evaluation of magnetic field levels in the automotive…

This document specifies requirements that are applicable to those active implantable medical devices intended to treat bradyarrhythmias and devices that provide therapies for cardiac resynchronization. The tests that are specified in this document are type tests, and are to be carried out on samples of a device to show compliance. This document was designed for bradyarrhythmia pulse generators…

1 Scope and application 1.1 General This Standard provides rules and requirements for the design, fabrication, and erection of a broad range of steel structures based on limit states design approach. The term “steel structures” refers to structural members and frames that consist primarily of structural steel components, including structural steel acting compositely with concrete, and…

1 Scope 1.1 This Standard applies to unvented portable type gas camp heaters of the catalytic and infrared type only up to and including a maximum input of 12,000 Btu/hr (3 517 w) using propane, butane, and liquefied petroleum gas mixtures thereof, and intended for outdoor use. 1.2 This Standard applies to portable type gas camp heaters having a: a) regulated pressure; or b) non-regulated…

1 Scope 1.1 General This Standard provides criteria in accordance with the National Building Code of Canada, for the structural design and evaluation of structures or structural elements made from wood or wood products, including: a) graded lumber; b) glued-laminated timber; c) cross-laminated timber (CLT); d) unsanded plywood; e) oriented strand board (OSB); f) composite building…

This method determines the dimensional change of fabrics or garments, likely to occur in domestic laundering. A fabric specimen or garment is subjected to an appropriate combination of specified washing, drying and restoration procedures. This method contains six washing, five drying and one restoration procedure as listed below: Washing procedures 1 - 30 °C, low mechanical action, synthetic…

1 Scope This clause of Part 1 is applicable, except as follows: Addition: This standard applies to hand-held hedge trimmers which are designed for use by one operator for trimming hedges and bushes, including extended-reach hedge trimmers with a maximum length of 3,5 m. NOTE 101 The measurement of the length for extended-reach hedge trimmers is specified in 21.101. This standard is not…

1 Scope This part of IEC 61400 presents measurement procedures that enable noise emissions of a wind turbine to be characterised. This involves using measurement methods appropriate to noise emission assessment at locations close to the machine, in order to avoid errors due to sound propagation, but far away enough to allow for the finite source size. The procedures described are different…

This document provides guidance on the type and extent of soil characterization necessary for the evaluation of human exposure to substances present in possibly leading to adverse effects. It does not provide guidance on: — the design or selection of numerical models that can be used to estimate exposure; — potential exposure to radioactivity, pathogens or asbestos in soil. Background…
