This document specifies calculation methods for the total annual carbon dioxide (CO2) intensity of the plant where steel is produced through a blast furnace. NOTE          The steel plant is generally called “the integrated steel plant”. It includes boundary definition, material and energy flow definition and emission factor of CO2. Besides direct source import to the boundary, upstream and…

This document specifies calculation methods applicable to manufacturers using an electric arc furnace (EAF) to produce steel and having direct reduced iron (DRI) facilities within their premises. This document allows the user to cover those particular cases of agglomeration of iron ore on site. It can be used to evaluate the total annual carbon dioxide (CO2) emissions and the emission factor of…

IEC 62271-211:2024 is applicable to single- and three-phase direct connections between gas-insulated metal-enclosed switchgear (GIS) for rated voltages above 52 kV and transformer arrangements to establish electrical and mechanical interchange ability and to determine the limits of supply for the transformer connection. This second edition cancels and replaces the first edition of IEC 62271-211:…

This document specifies the safety requirements and measures for circular saw benches with or without sliding table or demountable power feed unit or both and capable of continuous production use, also known as “table saws” (in the USA), hereinafter referred to also as “machines”. The machines are designed to cut solid wood and material with similar physical characteristics to wood (see ISO 19085…

This document establishes the content for commercial specifications for concrete pumps which are used on building sites for concrete-mix delivery.

IEC 63272:2024 specifies the performance and functional characteristics of the on-site AC interruptible power supply systems and applies to new nuclear facilities and newly installed or upgraded on-site AC interruptible power supply systems. The specific design requirements for the components of the power supply system are defined by the IEC standards listed in the normative references and are…

IEC TS 62600-103:2024 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 TS 62600-103:2024 is concerned with the sub-prototype scale development of wave energy converters (WECs). It…

IEC TS 62600-103:2024 is concerned with the sub-prototype scale development of wave energy converters (WECs). It includes wave tank test programmes, where wave conditions are controlled so they can be scheduled, and first sea trials, where sea states occur naturally and the programmes are adjusted and flexible to accommodate the conditions. Commercial-scale prototype tests are not covered in this…

This pack contains IEC 61558-2-23:2024 EXV and IEC 61558-2-23:2024 RLV. IEC 61558-2-23:2024 deals with the safety of transformers for construction sites and power supply units incorporating transformers for construction sites. Transformers incorporating electronic circuits are also covered by this document. This third edition cancels and replaces the second edition published in 2010. This…
