Application-specific standards

Power-operated guards
EN 953:1997+A1:2009 Power-operated guards, type B standard
Requirements for guards are described in detail in the product standard DIN EN 953.
Particular attention must be paid to Section "5.2.5.2 Operating forces".
Excerpt from EN 953:1997+A1:2009, Section 5.2.5.2:
"Where guards are power operated they shall not be capable of causing injury (e.g. from
contact pressure, force, speed, sharp edges). Where a guard is fitted with a protective
device which automatically initiates reopening of the guard, the force to prevent the guard
closing shall not exceed 150 N. The kinetic energy of the guard shall not exceed 10 J. Where
no such protective device is fitted these values shall be reduced to 75 N and 4 J
respectively."
Machine tools – Safety – Turning machines
EN ISO 23125:2010+A1:2012 Machine tools safety – Turning machines, type C standard
Section 5.2.2.2 b) "For power-operated guards"
Excerpt from EN ISO 23125:2010+A1:2012, Section 5.2.2.2 b):
"3) the force to prevent the guard from closing shall not exceed 75 N and the kinetic energy
of the guard shall not exceed 4 J. When the guard is fitted with a protective device which
automatically initiates reopening of the guard on actuation, this may be a maximum of 150 N
and the kinetic energy a maximum of 10 J;"
Injection molding machines
DIN EN 201:2009 Plastics and rubber machines – Injection molding machines – Safety
requirements; German version EN 201:2009, type C standard
Section 5.8.10 "Power operated guards"
Excerpt from DIN EN 201:2009, Section 5.8.10:
"For power operated guards the following additional requirements shall apply:
● where there are contact forces more than 75 N and less or equal to 150 N, a pressure
sensitive edge in accordance with EN 1760-2:2001+A1:2009 shall be supplied. Actuation
of the sensitive edge shall stop the closing movement of the guard in accordance
with EN ISO 13849-1:2008, PLr = c;
● where there are contact forces more than 150 N, these shall not exceed 300 N and a
pressure sensitive edge in accordance with EN 1760-2:2001+A1:2009 shall be supplied.
Actuation of the sensitive edge shall stop the closing movement of the guard in
accordance with EN ISO 13849-1:2008, PLr = c, and allow the reversing movement
without creating any additional hazard. Closing of the guard shall be achieved by a hold-
to-run control device in accordance with of EN ISO 13849-1:2008, PLr = c; ..."
