A3.6             INTERPRETATIONS TO EN81-1: 1978, EN81-1: 1985, EN81-1: 1998, EN81-2: 1987, EN81-2: 1998

 

Safety standards are very necessary, but the documents that describe them are boring.  The same thing goes for Interpretations to the standards.  Until there is an argument.  Then every word is picked over.  If you are a designer, manufacturer, installer, maintainer, owner, inspector or consultant you do need to keep up to date.  BSI will publish EN81-29 “Safety rules for the construction and installation of lifts - Lifts for the transport of persons and goods - Part 29: Interpretations”, as DD CEN TS 81-29:2005.  This contains a complete listing and description of interpretations to the current 1998 versions of EN81-1/2 (series 500-572) and a cross reference to those interpretations still relevant made to the earlier EN81-1/2 standards (series 1‑272).  These latter interpretations were published by BSI in BS HB 10105: 2000 as the Lifts Handbook “An explanatory supplement to BS5655: Parts 1 and 2”.  This seems to have been mysteriously withdrawn from the BSI catalogue.

 

The table below gives the interpretation number on a clause by clause basis with a “X” in the column of the standards relevant to the clause.  Only a brief description is given, so it will necessary to examine the actual text to see the full text.

 

New interpretations are issued on an ad hoc time scale.  Eventually these are collected together and published. This does mean you can be out of date without knowing it.  Elevatori publishes the basic text of each new interpretation shortly after it becomes available.  An additional table is provided below at the end of the Part 29 series showing Interpretations 573-580, the abstracts of which have been recently published in Elevatori.

 

A WARNING Interpretations do not have the same status as the standards to which they are related. However the application of interpretations should give to the interested parties confidence that the relevant standard has not been wrongly applied.
