BRITISH STANDARD

National foreword
This British Standard is the UK implementation of EN 61587-1:2017. It is
identical to IEC 61587-1:2016. It supersedes BS EN 61587-1:2012, which
is withdrawn.
The UK participation in its preparation was entrusted to Technical
Committee EPL/48, Electromechanical components and mechanical
structures for electronic equipment.
A list of organizations represented on this committee 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.
