This document describes a simple classification system for coals providing — guidance on the selection of the appropriate ISO standard procedures for the analyses and testing of coals, — international comparison of coals in terms of some key characteristics, — descriptive categorization of coals. The system is applicable to coals of all ranks, but care is required in…

IEC TS 62939-2:2018(E), which is a Technical Specification, provides an architecture to define interfaces for the information exchange between smart equipment/systems from the demand side and the power grid. It facilitates the interoperability between the IEC common information model (CIM) and customer facility standards for smart grid applications. This document presents one possible…

IEC 60095-1:2018 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 60095-1:2018 is applicable to lead-acid batteries with a nominal voltage of 12 V, used primarily as a power…

This document specifies procedures for measuring and reporting the noise emission of information technology and telecommunications equipment. NOTE 1 This document is considered part of a noise test code (see 3.1.2) for this type of equipment and is based on basic noise emission standards (see 3.1.1) ISO 3741, ISO 3744, ISO 3745, ISO 9295 and ISO 11201. The basic emission quantity is the A-…

This document specifies principles for the design of highly automated aspects of highly automated machines and vehicles (e.g. agricultural tractors, tractor implement systems, implements and self-propelled machinery) during agricultural field operations. In addition, it provides guidance on the type of information on safe working practices (including information about residual risks) to be…

IEC 60335-2-15:2012+A1:2016+A2:2018 deals with the safety of electrical appliances for heating liquids for household and similar purposes, their rated voltage being not more than 250 V. Appliances intended for normal household and similar use and that may also be used by laymen in shops, in light industry and on farms, are within the scope of this standard. If the appliance is intended to be used…

1 Scope 1.1 This Standard applies to single- and multiple-conductor fire alarm and signal cables with a maximum nominal voltage rating of 300 V and a minimum temperature rating of 60 °C for use in buildings and other structures in dry, damp, or wet locations in accordance with the Canadian Electrical Code, Part I. 1.2 Because other CSA Group Standards specify requirements for certain…

1 Scope 1.1 This Standard outlines a PV module testing protocol for quality assurance programs. It is intended to be used by financial institution and insurers, developers, independent engineers, and manufacturers. It provides best practices for photovoltaic module testing protocol for quality assurance programs. 1.2 This Standard is intended to be a stand-alone document that does not…
