  30. Structure of the EN81 Series of Standards EN 81-10

  31. Structure of the EN81 Series of StandardsBasic Principles • EN81 represents a series of standards in 8 different categories • 1: Basics & Interpretations • 2: Lifts for Transport of Persons & Goods • 3: Lifts for Transport of Goods only • 4: Special Lifts for Transport of Persons & Goods • 5: Evaluations • 6: Documentation for Lifts • 7: Particular Applications Persons & Goods • 8: Existing Lifts • Each category represents number of standards • Identification of the each standards is defined as: • EN81+ category + designated number in the category • Example: EN81-72 (Fire-fighters lifts)

  32. Legend: Standard published Standard in development Possible future development Standards under revision Structure of the EN81 Series of StandardsOverview today EN 81 Family of Standards EN 81-1x Basics & Interpretations EN 81-2x Lifts for Transport of Persons & Goods EN 81-3x Lifts for Transport of Goods only EN 81-4x Special Lifts for Transport of Persons & Goods EN 81-5x Evaluations EN 81-6x Documentation for Lifts EN 81-7x Particular Applications Persons & Goods EN 81-8x Existing Lifts 10 System of EN81 Series of Standards 1 Passenger & Goods/Passenger Lifts-Electric 30 Service Lifts 40 Stairlifts & Inclined Lifting Platforms 60 Technical File & Instruction for Use Special Lifts for Persons & Goods 70 Accessibility for Persons with Impaired Mobility 80 Improvement of Safety of Existing Lifts 51 Type Examination of Lifts 31 Accessible Goods-only Lifts 41 Vertical Lifting Platforms 61 Technical File & Instruction for Use Goods only Lifts 71 Vandal Resistant Lifts 81 Modernization of Lifts 12 Procedures for risk Assessment (ISO/TS 14798 is being applied today) 2 Passenger & Goods/Passenger Lifts-Hydraulic 58 Landing Door Fire Test 43 Lifts for Access to Workplaces 68 Remote Monitoring 72 Firefighters Lifts 82 Accessibility Improvement of Existing Lifts 21 Passenger Lifts in Existing Buildings 22 Passenger Lifts, Inclined 73 Behavior of Lifts in the Event of Fire 83 Vandal resistance Improvement of Existing Lifts 28 Remote Alarm for Passenger & Goods/Passenger Lifts 76 Use of Lifts for the Evacuation of Disabled 29 Interpretations 77 Lifts Subject to Seismic Conditions

  33. Structure of the EN81 Series of StandardsRationale • Groups a number of dedicated stand alone standards • Deal with all type of lift drives • Avoid redundancy in requirements • Address all type of interested parties • Users could easily identify the safety standards related to lifts • Simplify standardisation work
