M/511 - Mandate to LVD
Mandate to CEN, CENELEC and ETSI relating to harmonised standards in the field of the Low Voltage Directive
Mandate M/511 tasks CEN, CENELEC, and ETSI with developing harmonised standards to support the implementation of the Low Voltage Directive (LVD). These standards aim to ensure the safety and compliance of electrical equipment operating within specified voltage limits placed on the EU market. By harmonising technical requirements, the mandate facilitates regulatory clarity, product conformity assessment, and interoperability across member states, thereby enhancing consumer protection and internal market efficiency. The work under this mandate assists manufacturers in demonstrating compliance with essential health and safety requirements under the LVD.
Purpose
The mandate M/511 is issued to harmonise standards within the scope of the Low Voltage Directive (LVD). Its primary purpose is to commission standardisation bodies to develop and revise standards that ensure the safety and compliance of electrical equipment operating within specified voltage limits. This supports the effective implementation of the LVD across the European Union.
Standardisation request
The request is addressed to the European standardisation organisations CEN (European Committee for Standardization), CENELEC (European Committee for Electrotechnical Standardization), and ETSI (European Telecommunications Standards Institute). These bodies are tasked with preparing harmonised standards that align with the essential safety requirements laid down in the Low Voltage Directive.
Expected deliverables
The deliverables include harmonised standards covering the safety requirements for electrical equipment operating within the voltage limits defined in the Low Voltage Directive. These standards should enable manufacturers to demonstrate conformity with the directive’s provisions, thereby facilitating free movement of electrical products within the EU market.
Context
The Low Voltage Directive provides a regulatory framework to ensure the safety of electrical equipment within certain voltage thresholds placed on the EU market. Standardisation mandates like M/511 help to establish the technical specifications necessary for compliance, reducing trade barriers and enhancing consumer safety. This mandate directs the main European standardisation organisations to coordinate the development of these harmonised standards.
This mandate covers the development of harmonised standards for electrical equipment operating within certain voltage limits intended for use with a voltage rating of between 50 and 1000 V for alternating current and between 75 and 1500 V for direct current, ensuring safety and compliance with the Low Voltage Directive requirements.

This document provides requirements and specific guidance for the safe operation and maintenance of optical fibre communication systems (OFCSs). In these systems, optical power is possibly accessible outside the confines of the transmitting equipment and/or at great distance from the optical source.
This document requires the assessment of hazard level at each accessible location of the OFCS as a replacement for product classification according to IEC 60825-1. It applies to the installed OFCS as an engineered, end-to-end assembly for the generation, transfer and receipt of optical radiation arising from lasers, light-emitting diodes (LEDs) or optical amplifiers, in which the transference is by means of optical fibre for communication and/or control purposes.
NOTE 1 Throughout this document, a reference to 'laser' is taken to include LEDs and optical amplifiers.
Individual components and subassemblies that fall under the definition of a laser product are subject to the applicable subclause(s) of IEC 60825-1. This document is applicable to individual components and subassemblies intended to be installed within OFCSs.
This document does not apply to optical fibre systems primarily designed to transmit optical power for applications such as material processing or medical treatment.
In addition to the hazards resulting from laser radiation, OFCSs possibly give rise to other hazards, such as fire.
This document does not address safety issues associated with explosion or fire with respect to OFCSs deployed in explosive atmospheres.
NOTE 2 The hazard presented by optical radiation emerging from a fibre is determined by the wavelength and power emerging from the fibre and also by the optical characteristics of the fibre itself (see Annex A).

IEC 63497:2026, which is a product standard, is intended to specify the EMC, performance and safety requirements of shunt-connected active correction devices (ACD) with rated system voltages not exceeding 1 000 V AC or 1 500 V DC. These devices can be either cord or permanently connected. They can be movable, stationary, or fixed devices. An ACD includes both a static VAR generator (SVG) and an active harmonic filter (AHF). The primary function of a shunt connected ACD is to do one or more of the following: - active harmonic filtering; - reactive power compensation; - unbalanced load compensation. Additional functions of a shunt-connected ACD, not addressed by this document, can be the following: - flicker compensation; - interharmonic component filtering. In case of hybrid devices, combining a passive harmonic filter and an ACD, this document covers only the active part. This document does not cover - active mitigation functions part of another device (variable speed drive, uninterruptible power supply, dynamic voltage restorer, etc.), - switched power capacitors, - switched inductors, - passive harmonic filters, - energy storage converters, and - series-connected active correction devices.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/511 is a European Standardization Mandate titled "Mandate to CEN, CENELEC and ETSI relating to harmonised standards in the field of the Low Voltage Directive". Mandate to CEN, CENELEC and ETSI relating to harmonised standards in the field of the Low Voltage Directive There are 1688 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
