This document specifies a method to determine the specific aerobic biodegradation rate of solid, non-water soluble plastic materials under mesophilic conditions. NOTE      The specific aerobic biodegradation rate (which, strictly speaking, is a specific mineralization rate, implying the assessment of the conversion of organic carbon into CO2 but neglecting biomass formation) is expressed as…

This document defines and promotes the use of a standard code (ISSN) for the unique identification of serials and other continuing resources. Each International Standard Serial Number (ISSN) is a unique identifier for a serial or other continuing resource in a defined medium whether print or electronic. This document also allows for grouping related continuing resources into clusters identified…

This document specifies the geometry and method of use (installation and operating conditions) of Venturi tubes[1] when they are inserted in a conduit running full to determine the flow rate of the fluid flowing in the conduit. This document also provides background information for calculating the flow rate and is applicable in conjunction with the requirements given in ISO 5167-1. This document…

IEC 63044-5-1:2017+AMD1:2022 is a product family standard that sets the minimum level of EMC performance for the HBES/BACS network in addition to the product EMC standards for HBES/BACS devices. It also applies to devices used within an HBES/BACS network for which no specific HBES/BACS product EMC standard exists. In addition, it defines EMC requirements for the interface of equipment intended to…

IEC 63044-5-2:2017+AMD1:2022 is a product family standard that sets the minimum level of EMC performance for the HBES/BACS network in addition to the product EMC standards for HBES/BACS devices. It also applies to devices used within an HBES/BACS network for which no specific HBES/BACS product EMC standard exists. In addition, it defines EMC requirements for the interface of equipment intended to…

IEC 63044-5-3:2017+AMD1:2022 is a product family standard that sets the minimum level of EMC performance for the HBES/BACS network in addition to the product EMC standards for HBES/BACS devices. It also applies to devices used within an HBES/BACS network for which no specific HBES/BACS product EMC standard exists. In addition, it defines EMC requirements for the interface of equipment intended to…

This document specifies a method of testing the resistance of the upper assembly of inspection chambers and manhole components against surface and traffic loading. It is not applicable to requirements for testing the cover and frame. Those requirements are specified in EN 124-1 or other standards, depending on the material. NOTE    Upper assembly components normally include shafts or risers,…

1.1 These requirements apply to low voltage luminaire systems whose electrical power is derived from photovoltaic modules. Systems include, at a minimum, a photovoltaic (PV) module, storage batteries, one or more co-located luminaires, and controls to manage the energy flow between these subassemblies. These systems are intended to be installed in accordance with: a) CSA C22.1, the Canadian…

This document provides information based on a study of the characteristics of head-mounted displays (HMDs) regarding the ergonomics of human–system interaction. Although this document covers the broad range of ergonomics issues that arise, it specifically provides more-detailed information about the visual aspects of the interaction, and it provides information that could form the basis for…

IEC 61290-1:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61290-1:2022 applies to all commercially available optical amplifiers (OAs) and optically amplified subsystems.…
