29、er by publication of an identical text orby endorsement, at the latest by June 2004, and conflicting national standards shall be withdrawn at the latest byJune 2004.Regulations concerning the safety upgrading of existing lifts vary from member state to member state and havenot, to date, been harmoni

30、sed at either international or European level.CEN/CENELEC have embarked on a programme of work to produce a series of related machinery and lift safetystandards as part of the process of European harmonisation. This standard both makes use of and refers toEN 292 parts 1 and 2 and most of the EN 81 s

31、eries of standards (see clause 2).This standard is part of the EN 81 series of standards: “Safety rules for the construction and installation of lifts”.This is the first edition of the standard.Annexes A and B are informative.This document includes a Bibliography.According to the CEN/CENELEC Interna

32、l Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain,

33、 Sweden, Switzerland and the United Kingdom.EN 81-80:2003 (E)5IntroductionBackground of this standardMore than 3 million lifts are in use today in EU and EFTA and almost 50 % were installed more than 20 years ago.Existing lifts were installed to the safety level appropriate at that time. This level

34、is less than todays state of the artfor safety.New technologies and social expectations have led to todays state of the art for safety. This has led to the situationtoday of different levels of safety across Europe causing accidents. However, users and authorised persons expecta common acceptable le

35、vel of safety.In addition, there is a growing trend for people to live longer and for disabled people to expect access and designfor all. Therefore it is especially important to provide a safe means of vertical transport for disabled and elderlypersons without supervision.Lift attendants and in many

36、 cases building caretakers are not so common anymore, so it is important that relevantsafety features for the rescue of trapped persons should be provided.Furthermore the life cycle of a lift is longer than most other transportation systems and building equipment, whichtherefore means that lift desi

37、gn, performance and safety can fall behind modern technologies. If existing lifts arenot upgraded to todays state of the art of safety the number of injuries will increase (especially in buildings whichcan be accessed by the general public).With the freedom of movement of people within the EU for bo

38、th users and authorised persons, familiarisation withthe different installations is becoming more and more difficult.Approach of this standardThis standardcategorises various hazards and hazardous situations, each of which has been analysed by a riskassessment;is intended to provide corrective actio

39、ns to progressively and selectively improve, step by step, the safety of allexisting passenger and goods passenger lifts towards todays state of the art for safety;enables each lift to be audited and safety measures to be identified and implemented in a step by step andselective fashion according to

40、 the frequency and severity of any single risk;lists the high, medium and low risks and corrective actions which can be applied in separate steps in order toeliminate the risks.Other designs to previous national regulations or standards, providing they have an equivalent safety level, may beacceptab

41、le.Use of this standardThis standard can be used as a guideline for:a) national authorities to determine its own programme of implementation in a step by step process via a filteringprocess (see annex A) in a reasonable and practicable1)way based on the level of risk (e.g. extreme, high,medium, low)

42、 and social and economic considerations;b) owners to follow their responsibilities according to existing regulations (e.g. Use of Work Equipment Directive);1) “Reasonable and practicable” is defined as follows: “In deciding what is reasonably practicable the seriousness of a risk toinjury should be

43、weighted against the difficulty and cost of removing or reducing that risk. Where the difficulty and costs arehigh, and a careful assessment of the risk shows it to be comparatively unimportant, action may not need to be taken. On theother hand where the risk is high, action should be taken at whate

44、ver cost.”EN 81-80:2003 (E)6c) maintenance companies and/or inspection bodies to inform the owners on the safety level of their installations;d) owners to upgrade the existing lifts on a voluntary basis in accordance with c) if no regulations exist.In making an audit of an existing lift installation

45、 annex B can be used to identify the hazards and corrective actionsin this standard. However, where a hazardous situation is identified which is not covered in this standard aseparate risk assessment should be made. This risk assessment should be based on ISO/TS 14798(see bibliography).EN 81-80:2003

46、 (E)71 Scope1.1 This European Standard gives rules for improving the safety of existing lifts with the aim of reaching anequivalent level of safety to that of a newly installed lift by the application of todays state of the art for safety.NOTE Due to situations such as the building design etc. it ma

47、y not be possible in all cases to reach todays state of the artfor safety.1.2 This standard applies for permanently installedelectric lifts, with traction or positive drive;hydraulic liftsserving defined landing levels, having a car designed for the transportation of persons or persons and goods and

48、moving between guide rails inclined not more than 15 to the vertical.1.3 This standard includes the improvement of safety of existing passenger and goods passenger lifts for:a) users;b) maintenance and inspection personnel;c) persons outside the well, machine room and the pulley room (but in their i

49、mmediate vicinity);d) any authorised persons.1.4 This standard is not applicable to:a) lifts with drive systems others than those defined in EN 81-1 or EN 81-2;b) lifting appliances such as paternosters, mine lifts, theatre lifts, appliances with automatic caging, skips, lifts andhoists for building and public works sites, ships hoists, platforms for exploration or drilling at sea, constructionand maintenance appliances;c) installations where the inclination of the guide rails to the vertical exceeds 15;d) safety during transport, installation, repai
