Overview
This standard specifies the additional or deviating requirements to EN 81-20:2014 for new passenger and goods passenger lifts, which may be used for firefighting and evacuation purposes under firefighters control. This is the second version of the standard. EN 81-72:2015 is a full revision of the standard which reflects developments since the publication of EN 81-72:2003 and experience gained from its application. Consequently, most clauses have some changes. The main changes can be identified thus: - Revision of the elements dealing with building design and the inclusion of a new informative annex on the building interface. Items to be considered in the use of pressurization of lift wells have been added including the noise level at the fire communication points. - Deletion of the requirement for a firefighters lift to serve every floor of the building. The floors to be served are assumed to be determined as part of the design of the building for fire. - New requirements for protection of electrical equipment against water; in the lift well and the roof and walls of the lift car. - New measures to prevent water ingress into the lift well which are strongly preferred over measures to control the level of water in the lift pit alone. The measures considered are described in a new annex on water management. - Revision of clauses dealing with the rescue of trapped firefighters with rationalized requirements for movable ladders and reduced maximum distance between consecutive landings. The use of fixed ladders and rope ladders has been removed. - New requirements for the interface between firefighters lift switches and the control system. - New requirements for dual entry lift cars where not all the safe areas to be used in firefighting operations are on the same side that is more than one car door could be used during firefighting operations. - Revision of requirements for the control system including new requirements for when a firefighter's key switch is used in the lift car (subject to negotiation). Revised requirements, in phase 2, for car doors to close under constant pressure from door close or car call buttons and for opening. This standard contains the German version of EN 81-72:2015 which has been prepared by Technical Committee CEN/TC 10 "Lifts, escalators and moving walks" at the European Committee for Standardization (CEN). This document will replace EN 81-72:2003. The national interests during the preparation were represented by Working Committee NA 060-33-01 AA "Aufzüge" ("Lifts") of the Standards Committee Mechanical Engineering (NAM) at DIN. Representatives of manufacturers and users of lifts, and of the employers' liability insurance associations contributed to this standard.
