higher Performance stanDarD en14052
That was the common EN 397, but in
2005 a higher performance standard
was defined as EN14052, making
available an industrial safety helmet
with considerably enhanced crown
penetration resistance and side
impact protection.
EN397
EN14052 introduced an impact test
in which the helmet is hit twice, once
close to the crown by a 5kg weight
dropped from 2 metres, and again by
the same weight dropped from one
metre and striking the shell at between
15 and 60 degrees, to test side impact
performance. The standard also
includes a two strike penetration test
with a 1kg flat bladed striker. This is
first dropped onto the crown area of the
helmet from 2.5 metres, and then again
onto the shell from 2 metres at an angle
between 15 and 60 degrees.
High performance industrial helmets
protect the wearer from falling objects
and off crown impacts and the resulting
brain, skull and neck injury. Although
some emergency services use the
higher specification helmets, there are
no regulations mandating this standard

and Technical Support Director, JSP
JSP testing procedures exceed requirements
for both EN397 and EN10452
EN10452
in other working environments, and
only one manufacturer is producing a
high performance industrial helmet for
the high risk industries such as mining
and tunnelling, demolition, construction,
refineries, and offshore working.
