This European Standard specifies the safety rules related to new passenger and goods/passenger lifts permanently installed in existing buildings where in some circumstances due to limitations enforced by building constraints, some requirements of EN 81 20:2014 cannot be met (see also 4th sentence of Introduction).This European Standard addresses a number of these constraints and gives requirements for alternative solutions. It is intended to be read and applied in conjunction with the European Standard EN 81-20:2014.This European Standard covers:-either the construction and installation of one or more complete new lift(s) including new well and machinery spaces in an existing building; or-the replacement of one or more existing lift(s) by new ones in existing well(s) and machinery spaces.This European Standard does not cover:-replacement or modifications of some parts to a lift already installed;-other applications outside of the scope of EN 81 20:2014.
