3、EN 81-21:2009.This standard gives the safety rules for the installation of new lifts intoexisting buildings where compliance with BS EN 81-1:1998 or BS EN 81-2:1998 is not possible due to problems with the existingmaterial fabric of the building, such as the lack of available space forpit and headro

4、om.When installing new lifts in the UK users of this standard should beaware that the Lifts Regulations (Statutory Instrument 1997 No. 831)require any lift installed without permanently available refuge space atextremes of travel to be subject to prior approval by the Department forBusiness, Innovat

5、ion and Skills (BIS).This refuge space has previously been agreed with BIS as being thatrequired in BS EN 81-1:1998, Subclauses 5.7.1.1 d), 5.7.2.2 c), 5.7.3.3a) and BS EN 81-2:1998, Subclauses 5.7.1.1 d), 5.7.2.3 a).Therefore, lifts installed into existing buildings where such refuge spacesare not

6、permanently available should obtain prior approval from BIS.In addition this standard gives rules for the continued use of perforatewell enclosures, where already installed. Such enclosures have notbeen described in lift standards since the 1970s and are as such to beavoided where possible. It is no

31、is document is a type C standard as stated in EN ISO 12100. When provisions of this type C standard are different from those stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and bu

32、ilt according to the provisions of this type C standard. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. Where one or several requirements in EN 81-1 or EN 81-2 !deleted text“ cannot be fulfilled, due t

33、o reasons such as the constraints of the structure of the existing building, the corresponding requirements in this European Standard apply. According to section 2.2 of Annex I to the Lifts Directive, the application of alternative measures to prevent the risk of crushing above and underneath the li

34、ft car is restricted to installations where the requirement for free space or refuge is impossible to fulfil and may be subject to prior approval by national authorities. The main concern dealt with in this standard is the reduction of top and pit clearances that may be required due to site conditio

35、ns. The adopted principle of safety is based on two levels of achievement: first by means of an electrical stopping of the lift car, then by means of a mechanical stopping of the lift car. When drafting this standard, it has been considered for reduced overhead and pit the following: a) Risk reducti

36、on measures that rely solely on operations in compliance with procedures are considered as not acceptable, except in a few situations in which mistake-proof solutions are not available (e.g. some activities in repair and installation in which safety devices cannot be operational); b) The risk reduct

37、ion measures shall be automatically (without any intervention) activated, or may be manually activated if mistake-proof-by-design, or a combination of both is used.

38、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 81-1 and EN 81-2 cannot be met (see also 4thsentence of Introduction). This European Standard addres

39、ses a number of these constraints and gives requirements for alternative solutions. It shall be read and applied in conjunction with the European Standards EN 81-1 or EN 81-2 !deleted text“, including their Clause 0. This European Standard covers: Either the construction and installation of one or m

40、ore 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 insta

41、lled; Other applications outside of the scope of EN 81-1 or EN 81-2. 2 Normative references The following referenced documents are indispensable for the application of this document.
