BSI will assume no liability whatsoever for the,failure on the part of any user of this standard not to consider this aspect.,JYecautions are urged to ensure that comingling of MIO nuts to the two standards,concerned is avoided.,Compliance with a British Standard does not of itself confer immunity,from legal obligations.,Summary of pages,This document comprises a front cover, an inside front cover, the EN title page,pages 2 to 6, an inside back cover and a back cover,This British Standard, having,been prepared under the Amendments issued since publication,direction of the Enaineerina .,Sector Board, was published Anid.
