This document defines the conceptual framework and mechanisms for mapping information elements from building information modelling (BIM) to geographic information systems (GIS) to access the required information based on specific user requirements.
The conceptual framework for mapping BIM information to GIS is defined with the following three mapping mechanisms:
—     BIM to GIS perspective definition (B2G PD);
—     BIM to GIS element mapping (B2G EM);
—     BIM to GIS level of detail (LOD) mapping (B2G LM).
This document does not describe physical schema integration or mapping between BIM and GIS models because the physical schema integration or mapping between two heterogeneous models is very complex and can cause a variety of ambiguity problems (see Annex D). Developing a unified information model between BIM and GIS is a desirable goal, but it is out of the scope of this document.
This document is applicable to the following concepts:
—     definition for BIM to GIS conceptual mapping requirement description;
—     definition of BIM to GIS conceptual mapping framework and component;
—     definition of mapping for export from one schema into another.
This document does not apply to the following concepts:
—     definition of any particular mapping application requirement and mechanism;
—     bi-directional mapping method between BIM and GIS;
—     definition of physical schema mapping between BIM and GIS;
—     definition of coordinate system mapping between BIM and GIS;
—     definition of relationship mapping between BIM and GIS;
—     implementation of the application schema.
NOTE            For cases involving requirements related to geo-referencing for providing the position and orientation of the BIM model based on GIS, other standards exist such as ISO 19111 and the Information Delivery Manual (IDM) from buildingSMART on Geo-referencing BIM.

This document specifies requirements for a valuation of energy related investments (VALERI). It provides a description on how to gather, calculate, evaluate and document information in order to create solid business cases based on Net Present Value calculations for ERIs. The standard is applicable for the valuation of any kind of energy related investment.
The document focusses mainly on the valuation and documentation of the economic impacts of ERIs. However, non-economic effects (e.g. noise reduction) that can occur through undertaking an investment are also considered. Thus, qualitative effects (e.g. impact on the environment) - even if they are non-monetisable - are taken into consideration.

The content of the corrigendum 1 of amendment 1 (2025-12) applies only to the French version.

This document lays down a framework for a standardization project to establish and document best practice in the design and execution of smart and sustainable services made available by local government to citizens, both for residents and for visitors to a community. This document sets out the basic principles that are needed to be observed across the full range of services to be provided; it does not cover specific services.
The project covers services, whether these are directly delivered by authorities or whether their delivery is outsourced to arms-length public bodies or private enterprises.
The project does not cover specific technologies used in the delivery of electronic services.
The work takes due account of, and complement, the work of ISO/TC 176 concerning local authorities’ quality management systems, and of ISO/TC 312 concerning service excellence.

IEC/TR 61000-3-15:2011(E) is concerned with the critical assessment of existing and emerging national and international standards for single and multi-phase dispersed generation systems up to 75 A per phase, particularly converters connected to the public supply low voltage network. This Technical Report intends to serve as a starting point and to ultimately pave the way for the definition of appropriate EMC requirements and test conditions. This Technical Report is limited to EMC issues (immunity and emission) up to 9 kHz and does not include other aspects of connection of generators to the grid. This Technical Report focuses on emission caused by distributed generation (mainly harmonics and inter-harmonics, DC emissions flicker, rapid voltage changes and fluctuations), as well as immunity aspects to normally occurring events in the public supply network (voltage dips and short interruptions, frequency variations, harmonics and interharmonics). Every effort has been made to utilize already existing emission and immunity standards, including the test set-up and existing test equipment in use.

This part of IEC 61000 provides guidance on principles which can be used as the basis for determining the requirements for the connection of unbalanced installations (i.e. three-phase installations causing voltage unbalance) to MV, HV and EHV public power systems (LV installations are covered in other IEC documents). For the purposes of this report, an unbalanced installation means a three-phase installation (which may be a load or a generator) that produces voltage unbalance on the system. The connection of single-phase installations is not specifically addressed, as the connection of such installations is under the control of the system operator or owner. The general principles however may be adapted when considering the connection of single-phase installations. The primary objective is to provide guidance to system operators or owners on engineering practices, which will facilitate the provision of adequate service quality for all connected customers. In addressing installations, this document is not intended to replace equipment standards for emission limits.
The report addresses the allocation of the capacity of the system to absorb disturbances. It does not address how to mitigate disturbances, nor does it address how the capacity of the system can be increased.
Since the guidelines outlined in this report are necessarily based on certain simplifying assumptions, there is no guarantee that this approach will always provide the optimum solution for all unbalanced load situations. The recommended approach should be used with flexibility and judgment as far as engineering is concerned, when applying the given assessment procedures in full or in part.
The system operator or owner is responsible for specifying requirements for the connection of installations which may cause unbalance on the system. The disturbing installation is to be understood as the complete customer’s installation (i.e. including balanced and unbalanced parts).
Problems related to unbalance fall into two basic categories.
• Unbalanced installations that draw negative-sequence currents which produce negativesequence voltages on the supply system. Examples of such installations include arc
furnaces and traction loads (typically connected to the public network at HV), and three phase installations where the individual loads are not balanced (typically connected at MV and LV). Negative-sequence voltage superimposed onto the terminal voltage of rotating machines can produce additional heat losses. Negative-sequence voltage can also cause non-characteristic harmonics (typically positive-sequence 3rd harmonic) to be produced by power converters.
• Unbalanced installations connected line-to-neutral can also draw zero-sequence currents which can be transferred or not into the supply system depending on the type of
connection of the coupling transformer. The flow of zero-sequence currents in a grounded neutral system causes zero-sequence unbalance affecting line-to-neutral voltages. This is not normally controlled by setting emission limits, but rather by system design and maintenance. Ungrounded-neutral systems and phase-to-phase connected installations are not, however, affected by this kind of voltage unbalance.
This report gives guidance only for the coordination of the negative-sequence type of voltage unbalance between different voltage levels in order to meet the compatibility levels at the point of utilisation. No compatibility levels are defined for zero-sequence type of voltage unbalance as this is often considered as being less relevant to the coordination of unbalance levels compared to the first type of voltage unbalance. However, for situations where a nonzero impedance exists between neutral and earth with the system still being effectively grounded (i.e., where the ratio between zero-sequence, X0 and positive sequence reactance X1 is 0 < X0/X1 ≤ 3), this type of voltage unbalance can be of concern especially when the type of connection of t

The present document defines baseline security requirements for AI models and systems. The present document includes in its scope systems that incorporate deep neural networks, such as generative AI. For consistency, the term "AI systems" is used throughout the present document when framing the scope of provisions and the term "AI security", which is considered a subset of cybersecurity, is used when addressing any cybersecurity issues in the scope of the provisions. The present document is not designed for academics who are creating and testing AI systems only for research purposes (AI systems which are not going to be deployed).

This document provides general methods for measurement and calculation of quantities associated with human exposure to electromagnetic fields in the frequency range from 0 Hz to 300 GHz. It is intended specifically to be used for the assessment of emissions from products and comparison of these with the exposure limits for the general public given in Council Recommendation 1999/519/EC, and those given for workers in Directive 2013/35/EU, as appropriate. It also is intended to be used for assessment of human exposure to electromagnetic fields in the workplace to determine compliance with the requirements of Directive 2013/35/EU.
This standard deals with quantities that can be measured or calculated external to the body, notably electric and magnetic field strength or power density, and includes the measurement and calculation of quantities inside the body that form the basis for protection guidelines. In particular the standard provides information on:
- definitions and terminology,
- characteristics of electromagnetic fields,
- measurement of exposure quantities,
- instrumentation requirements,
- methods of calibration,
- measurement techniques and procedures for evaluating exposure,
- calculation methods for exposure assessment.
Where an applicable electromagnetic field standard specific to a product or technology exists it is expected to be used rather than this document. EN 62311:-, Table 1 gives a list of relevant standards.

IEC TR 61000-3-18:2024 which is a technical report, reports on the development of a methodology for adapting IEC equipment emission limits from IEC 61000-3-2 and IEC 61000-3-12 for use in regions not covered by these documents. It identifies gaps in the existing equipment emission limit standards concerning their international applicability and identifies public power system characteristics important for the evaluation of harmonic voltage performance. The purpose of adapting the above-mentioned IEC equipment harmonic emission standards in a particular region is to maintain similar electromagnetic compatibility (EMC) of equipment up to 75 A per phase in the public power systems in those regions.
NOTE The boundaries between the various voltage levels differ amongst different countries (see IEC 60050‑601:1985, 601-01-28). This document uses the following terms when referring to 50 Hz and 60 Hz system voltages:
- low voltage (LV) refers to Un ≤ 1 kV;
- medium voltage (MV) refers to 1 kV  - high voltage (HV) refers to 35 kV  EMC requirements can have economic and societal impacts; these have not been considered in the development of this document. The consideration of these factors generally occurs in the technical committees working on development and maintenance of emission limit standards.

IEC TR 61000-2-8:2002, which is a technical report, describes the electromagnetic disturbance phenomena of voltage dips and short interruptions in terms of their sources, effects, remedial measures, methods of measurement, and measurement results (in so far as these are available). They are discussed primarily as phenomena observed on the networks of public electricity supply systems and having an effect on electrical equipment receiving its energy supply from those systems.
“Voltage sag” is an alternative name for the phenomenon voltage dip.

EXAMPLE An elevator motor drive returning energy during braking.
This document provides limits and testing procedures for equipment in the range up to harmonic order 40 (h40), i.e. 2 000 Hz or 2 400 Hz depending on line frequency.
NOTE 1 It is possible that limits for frequencies in the range from 2 kHz to 9 kHz will be added in a future edition of this document.
NOTE 2 It is possible that limits and procedures for storage systems will be added in a future edition of this document.

This part of IEC 62271 provides guidance to suppliers, manufacturers, users, and waste operators of high-voltage switchgear and controlgear as well as their assemblies having a rated voltage above 1 kV AC and 1,5 kV DC, together with their associated auxiliary equipment, on environmentally conscious design, and on assessing environmental impacts when used in systems. This document also gives guidance on effective communication of environmental information throughout the entire life cycle.
This document provides guidance on the process and general aspects to select UN sustainable development goals (UN sustainable development goals (SDG)), especially those dealing with health and environmental impacts and their assessments, represented respectively by:
• SDG 3-Good Health and Well-being;
• SDG 6-Clean Water and Sanitation;
• SDG 7-Affordable and Clean Energy;
• SDG 12-Responsible Consumption and Production;
• SDG 13-Climate Action;
• SDG 14-Life Below Water;
• SDG 15-Life on Land.
This document gives guidance on the process and general aspects to implement environmentally conscious product design (ECD) principles, as given in IEC 62430, essential
for high-voltage electrical power equipment and power control equipment.
This document gives guidance on executing the life cycle assessment (LCA) based on product category rules (PCR) in accordance with IEC 63366, ISO 14040 and ISO 14044 and on applying the Type III environmental declaration in accordance with ISO 14025, both for high-voltage switchgear and controlgear. This guidance provides standardized product specific rules (PSR) summarized as follows:
1) Common rules for the LCA process describing functional units, system boundaries, life cycle inventory analysis, scenarios, environmental impact categories;
2) Common rules for communicating information about the presence of regulated substances and the materials contained in the product, according to IEC 62474;
3) Common rules for communicating information about the end-of-life treatment of the product including material efficiency.
This document does not address the environmental declaration programme, however it can be used by program operators.
This document focuses on describing the LCA process referring to the functional unit, system boundary, scenarios, etc.
Owing to variability of influencing factors, such as flows, allocations, not balanced and timestable energy mix under different programmes, equipment customization, durability related to environmental conditions, it is not possible to compare two similar high-voltage switchgear and controlgear analysed in different contexts.
This document does not address by-products from arcing which are generated in sufficiently small quantities such that their environmental impact can be neglected. Any by-product generated by arcing during the use of equipment is strongly dependent on operating conditions and cannot a priori be qualified nor quantified. However, they are not expected to be released in air and will be managed at end-of-life by a dedicated process.
EXAMPLE
During the use of high-voltage switchgear and controlgear the handlings of normally arced gas are covered by IEC 62271-4. When the volume of gaseous by-product is below 1 % of normally arced gas, it is not considered compared to the cut-off rules specified in this document. The scenarios related to the system boundary do not take into account leakages from failures except if an agreement is reached on this between user and manufacturer (see Table 7, item h).
Power transformers, low-voltage switchgear and controlgear, and the interconnections with such equipment are not covered by this document. Therefore, assemblies according to IEC 62271-202 or IEC 62271-212 comprising any of the above equipment are not within the scope of this document.
This document supports material efficiency for circular economy. However, one of the major issues related to remanufacturing is the consideration of used parts
