National foreword

This British Standard is the UK implementation of EN 474-10:2006+A1:2009.
It supersedes BS EN 474-10:2006, which is withdrawn.

The UK participation in its preparation was entrusted by Technical Committee
B/513, Construction equipment and plant and site safety, to Subcommittee
B/513/1, Earth moving machinery (International).

A list of organizations represented on this subcommittee can be obtained on
request to its secretary.

This publication does not purport to include all the necessary provisions of a
contract. Users are responsible for its correct application.

Compliance with a British Standard cannot confer immunity from
legal obligations.
