of EN ISO 12100-1 and EN ISO 12100-2 for hazards relevant but not significant, which are not dealt with by
this document.
5.1.2 Before using this document it is important to carry out a risk assessment of the machine to check that
it has the hazards identified in this clause.
5.1.3 For hazards which are to be reduced by the application of type B-standards referred to in this
document (EN 294, EN 349, EN 547-2, EN 547-3, EN 842, EN 894-1, EN 894-2, EN 894-3, EN 953,
EN 60204-1, EN 61310-1, EN 61310-2), the manufacturer shall carry out a risk assessment to establish the
requirements of these type B-standards which are to be applied. This specific risk assessment shall be part of
the general risk assessment of the machine.
5.2 Special requirements
5.2.1 Mechanical hazards
5.2.1.1 Crushing, shearing, cutting and entanglement
5.2.1.1.1 General
Means shall be incorporated to reduce the hazards created by exposed moving parts, including as appropriate:
barriers conforming to EN 294 to prevent contact with moving parts;
gaps at the end-of-travel conforming to EN 349;
guards conforming to EN 953.
Rotating shafts, in particular those with exposed keys and keyways or other projections that could cut or catch
shall be protected or guarded.
Fixed guards for reducing risks from contact with parts of a pump, except for the pump inlet screen
(see 11.3.2.6), shall be removable only by using a tool. It shall not be necessary to remove the guard in order for
the pump to function normally.
Covers giving access for adjustment or setting of controls or sensors whilst the pump is in operation shall be
secured against unintended opening both when open and closed, and as far as possible remain attached to
the pump when open but shall not be required to be interlocked.
Machined or cut parts exposed, or likely to be exposed, at any stage during installation, operation, or servicing of
the pump shall be treated to remove burrs, rags and sharp edges by radiusing or chamfering.
5.2.1.1.2 Operating controls
Operating controls shall be clearly identified (see 11.4.1) and easy to operate as specified in EN 894 (all parts).
Manual controls and other operating devices shall be easy to reach and operable without unreasonable effort.
Operating controls shall be designed to ensure that crushing hazards are avoided, in accordance with EN 349,
as well as shearing or cutting hazards (e.g. by providing adequate clearance).

5.2.1.2.4 Static test pressure
The static test pressure for boosted pumps p shall be 1,5 times the nominal delivery pressure, i.e.:
ps
p = 1,5 × p
ps N
For floating pumps and submersible pumps p = p .
ps N
5.2.1.2.5 Dynamic test pressure
The dynamic test pressure p shall conform to Tables 2 to 4.

5.2.1.2.6 Safety equipment
It shall be possible to fit safety equipment to ensure that:
n cannot be exceeded;
0
the temperature of the water cannot exceed 60 °C in any mode of operation;
the limit pressure p can be monitored or cannot be exceeded.

5.2.1.2.7 Forces and moments on pipe connections
For rotodynamic pumps forces and moments on pipe connections shall conform to EN ISO 5199, EN ISO 9905,
EN ISO 9908.
5.2.2 Electrical hazards
Only extra low voltage as specified in EN 60204-1:1997, 6.4.1 shall be used. The protection against direct
contact shall be min. IP 2X as specified in EN 60529.
