IEC 61000-4-6: 2023 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 150 kHz up to 80 MHz. NOTE 1 Product committees might decide to use the methods described in this document also for frequencies up to 230 MHz (see Annex B) although the methods and…

This document specifies a method to evaluate the capability of portable household air cleaners to reduce the concentration and viability of key experimentally generated bioaerosols in a specified chamber. Indoor air free of harmful microbes is important to the health of occupants. This is particularly relevant with regard to increased time spent indoors. Air cleaners are used to reduce the…

1 Scope 1.1 Applications This Standard applies to devices meeting the following conditions: a) stationary packaged systems designed for single family residential and small commercial applications; b) mCHP fuel gas devices, including different prime mover/generator types (e.g., steam, organic Rankine cycle, fuel cell, and IC); c) mCHP with net AC electrical output less than 10 kW; and d…

1 Scope 1.1 General This Standard specifies a test method for calculating the energy efficiency of electric vehicle supply equipment (EVSE) for direct current fast charging (DCFC) across a full range of load conditions. It defines operating modes, and provides energy efficiency minimum requirements for these operating modes. Note: Many owners and operators of DCFC are concerned with the amount…

1 Scope 1.1 General This Standard contains requirements for the material, design, manufacture, marking, and testing of serially produced, refillable Type HGV 2 containers intended only for the storage of compressed hydrogen gas for on-road vehicle operation. These containers a) are to be permanently attached to the vehicle; b) have a capacity of up to 1000 L (35.4 ft3) water capacity; and…

1 Scope 1.1 General This Standard applies to water pressure reducing valve for potable water distribution systems. The purpose of a water pressure reducing valve for potable water distribution systems (herein referred to as the “device”) is to reduce static and flowing pressures in water distribution systems. 1.2 Sizes This standard applies to nominal device sizes of 1/2, 3/4, 1, 1-1/4, 1-1/2…

1 Scope 1.1 General This Standard provides minimum requirements for the development and reporting of a natural asset inventory, which is the first step towards natural asset management. This Standard is designed to be sufficiently flexible that it can be applied in any jurisdictional context. It can also be used to include not only natural assets within a given jurisdictional boundary but also…

1 Scope 1.1 There is a commentary available for this Clause. This Standard covers the design, construction, operation, maintenance, deactivation, and abandonment of oil and gas industry pipeline systems that convey a) liquid hydrocarbons, including crude oil, multiphase fluids, condensate, liquid petroleum products, natural gas liquids, and liquefied petroleum gas; b) oilfield water; c)…

1 Scope and normative references This clause of Part 12 is applicable except as follows: 1.1 Replacement: This part of IEC 60730 applies to the partial evaluation of thermal motor protectors as defined in IEC 60730-1 for household and similar use, including heating, air conditioning and similar applications as well as for sealed (hermetic and semi-hermetic type) motorcompressors. NOTE A…

Scope Replacement: This document is applicable to the basic safety and essential performance of an anaesthetic workstation for administering inhalational anaesthesia whilst continuously attended by a professional operator. This document specifies particular requirements for a complete anaesthetic workstation and the following anaesthetic workstation components which, although considered as…
