Optical fibres - Part 1-1: Measurement methods and test procedures - General and guidance
IEC 60793-1-1:2022 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 60793-1-1:2022 lists and gives guidance on the use of documents giving uniform requirements for measuring and…
Plastics — Determination of specific aerobic biodegradation rate of solid plastic materials and disa...
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…
Information and documentation — International standard serial number (ISSN)
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…

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…

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…
