This European Standard specifies the safety rules for new escalators/moving walks replacing existing escalators/moving walks installed in existing buildings where, due to limitations enforced by building constraints, certain requirements of EN 115-1:2017 cannot be fully met. This standard shall only be used when replacing existing escalators/moving walks where structural constraints within an existing building make the installation of fully EN115-1:2017 compliant escalators/moving walks impossible. The escalator/moving walk installer must liaise with the customer and recommend altering the building structure in the first instance and deviations from EN115-1 should only be considered as a last resort. This standard addresses a number of these constraints, gives requirements for alternative solutions and covers:  the replacement of an existing escalator/moving walk by a new one in an existing building. This standard does not cover:  construction and installation of a new escalator / moving walk in  an existing building, which is not replacing an existing escalator/moving walk;  replacement or modifications of some parts of existing escalator/moving walk, e.g. intruss modernization;  major modifications of existing escalator/moving walk, e.g. change of the location (see EN 115-1:2017, Annex L);  other applications outside of the scope of EN 115-1:2017

This document specifies the emission limits in relation to electromagnetic disturbances and test conditions for lifts, escalators and moving walks, which are intended to be permanently installed in buildings. It is possible, however, that these limits do not provide full protection against disturbances caused to radio and TV reception when such equipment is used within distances given in Table 1. This document is not applicable for apparatus which are manufactured before the date of its publication

This document specifies the requirements for product quality and product testing of enamelled valves and pressure pipe fittings for untreated and potable water supply. It does not apply to chemical service glass-enamel and apparatus enamel.

This document specifies the technical requirements for the two-way communication system of passenger and goods passenger lifts, to communicate with a reception equipment. This document is not applicable to lifts installed before the date of its publication.

This document specifies dimensions, materials and performance requirements, including test methods, for combined temperature and pressure relief valves, of nominal sizes from DN 15 to DN 40, having working pressures ) from 0,3 MPa (3 bar) to 1,0 MPa (10 bar). Combined temperature and pressure relief valves control and limit the temperature and pressure of the water contained in a hot water heater to the valves rating pressure and a temperature not exceeding 100 °C and will prevent water to steam formation when other temperature controls fail. Combined temperature and pressure relief valves are classified having a maximum opening temperature range from 90 °C to 95 °C for class A and 75 °C to 80 °C for class B. They are not intended to act as an expansion valve and do not control cold water flow. Alone it does not constitute the control functions for a water heater. A combined temperature and pressure relief valve is an independently mechanically operating device, therefore operating without an external energy source. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information, see Annex B).
