Comprehensive Guide to EN 50520 Energy Efficiency Testing for Elevators and Escalators
Standard-Related Information
EN 50520 is a European standard that outlines the requirements for energy efficiency testing of elevators and escalators. This standard is based on the principles of ISO 50001, which sets out the requirements for energy management systems. The EN 50520 standard is designed to ensure that elevator and escalator manufacturers comply with EU regulations and directives related to energy consumption.
Legal and Regulatory Framework
The EN 50520 standard is governed by several international and national standards, including:
The European Commission has implemented several directives related to energy consumption, including:
Standard Development Organizations
The EN 50520 standard is developed and maintained by the European Committee for Electrotechnical Standardization (CENELEC). CENELEC is a non-profit organization that brings together national standards organizations from across Europe to develop and harmonize technical standards.
Standard Evolution and Update
Standards evolve and get updated regularly to reflect changes in technology, regulatory requirements, and industry best practices. The EN 50520 standard has undergone several revisions since its initial publication in 2011. The latest version of the standard was published in 2020 and includes updates to address new EU regulations and directives.
