Introduction
This document is a type C standard as stated in EN ISO 12100-1.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of the other standards, for machines
that have been designed and built according to the provisions of this type C standard.
1 Scope
1.1 This standard applies for
 curing injection machines with infeed and outfeed devices;
 curing injection machines with infeed and outfeed devices and loading devices.
This standard does not apply to portable/hand guided curing injection devices.
This standard deals with all significant hazards, hazardous situations and events relevant to machines,
appliances and machinery when they are used as intended and under the conditions foreseen by the
manufacturer (see Clause 4).
This document deals with all significant hazards, hazardous situations and events relevant to curing injection
machinery when they are used as intended and under conditions of misuse which are reasonably foreseeable
by the manufacturer (see Clause 4).
This document is not applicable to curing injection machines which are manufactured before the date of
publication of this document by CEN.
1.2 This standard covers the following types of curing injection machines:
Curing injection machines consist mainly of a single or multilane curing needle station, holding down clamp,
infeed and outfeed devices, machine frame and related drive system, and electrical, electronic, or pneumatic
components, depending on machine type.
Curing injection machines in the scope of this standard can be equipped with:
 infeed chute;
 splash guard flaps;
 single or multi-lane curing needle bars (needle station);
 holding down clamp;
 infeed and outfeed conveyor belt;
 infeed and outfeed rake;
 interlocked transport car at the outfeed side;
 loading device with delivery chute.
The product being processed (raw meat, game or raw fish) is fed by hand to the infeed device of the curing
injection machine. The infeed device transports the product to the needle station; the product is then pressed
against the infeed device by a holding down clamp. The needles of the needle station inject the curing liquid or
other fluids into the product. The outfeed device then transports the product away from the needle station.
This standard also covers the loading devices, which can be necessary in the case of machines with high
capacity and/or great height.
Curing injection machines in the scope of this standard can be stationary or mobile.
1.2.1 Curing injection machines with single or multi-lane curing needle bars, infeed and outfeed device at
the infeed and outfeed side (see Figure 1).

The access to the danger points at the movable parts of the holding down clamp and needle bar above the
infeed/outfeed device shall be prevented. This can be achieved e.g. by observance of all of the following
measures:
5.2.4.1 At the zone of the needle station which is moving up and down, above the infeed/out-feed device,
an enclosed housing shall be available. The guard shall be either fixed or movable. A movable housing and
doors or hatches shall be interlocked with the functioning of the machine.
5.2.4.2 The lowering motion of the needle station shall come to a standstill within 2 s, after activating the
interlocking device of the movable housing or of the doors/hatches.
For requirements for the interlocking of the movable housing or the doors/hatches see 5.2.1.
5.2.5 Zone 4
Infeed/ outfeed device (see Figure 10).
The access to the danger points between the infeed/outfeed device and the bottom reservoir and also the
outlet ports in the bottom reservoir shall be prevented. This shall be achieved by fulfilling all of the following
conditions:
5.2.5.1 The distance A between the infeed and outfeed device and the bottom reservoir shall be > 25 mm
(see Figure 10).
5.2.5.2 The curing liquid out-feed openings D in the bottom reservoir shall have a diameter of D < 25 mm
or a slot width S < 15 mm (see Figure 10).
5.2.5.3 The distance A between the bottom reservoir and the transport rake shall be > 25 mm (see
Figure 10).

5.2.6 Zone 5
Infeed/out-feed chutes (see Figures 4 and 5).
Access to the danger points at the nip points of the infeed/outfeed chutes shall be prevented. This can be
achieved by fulfilling the following condition:
The transition chute (fixed) shall directly pass over in the infeed/outfeed device (movable) and shall have an
angle of pitch > 90°.
5.2.7 Zone 6
Drive system (see Figures 4 and 5).
The access to the danger points on the drive system shall be prevented. This shall be achieved by fulfilling all
of the following conditions:
5.2.7.1 At the drive system safety guards (e.g. doors) shall be provided according to 3.2 and 3.3 of
EN 953:1997. The guards (e.g. doors) can be fixed guards or interlocking movable guards.
5.2.7.2 If guards have to be opened for changing the machine operation or cleaning these guards shall
be interlocked.
Requirements for interlocking of the guards shall be in accordance with 5.2.1.
5.2.8 Zone 7
Machine parts, e.g. guard covers (see Figure 5).
Movable machine components (e.g. guards) shall be prevented from falling into a closed position. This can be
achieved by observance of one of the following measures:
5.2.8.1 A non-driven guard shall be provided with e.g. a counter balance weight, or a spring, when the
guard in its open position is not far enough behind its centre of gravity to prevent it falling. The guard shall be
provided with a handle.
5.2.8.2 For power-operated guards the closing time of the last 250 mm (measured at the outer closing
edge) of the closing distance shall be > 4 s. The measuring point is located at the greatest opening width of
the guard. If a drive system malfunctions (e.g. piping or hose rupture) the motion of the cover shall be
interrupted.
5.2.9 Zone 8 to 11
5.2.9.1 Loading devices on curing injection machines (see Figure 5)
Loading devices shall comply with the requirements of EN 13288 as far as applicable. For additional
requirements for lift-tilt devices see 5.2.9.2.
NOTE Lift-tilt devices of various designs exist, e.g. with
- Fixed lifting arms for holding transport cars;
- Lifting arms which allow the transport car to swivel in a gondola and thus remain horizontal;
- Vertical pillar mast and forks for holding the transport car or container.
Lift-tilt devices can be free standing or connected to the curing injection machine.
5.2.9.2 Additional requirements for lift-tilt devices on curing injection machines
5.2.9.2.1 Installation
5.2.9.2.1.1 Lift-tilt devices shall be designed in such a way, that they are stable.
5.2.9.2.1.2 A special device shall be provided to prevent the lift-tilt device or the curing injection machine
from falling over if the loading device is lowering and meets an obstacle. This can be achieved by fulfilling one
of the following conditions:
 use of a hold to-run control for the lowering of the loading parts;
 use of gravity only for lowering of the loading device;
 special device on the machine or lift-tilt device so that powered descent of the loading device onto an
obstacle cannot cause instability. This can be a level switch, to automatically stop the descent, if the lift-tilt
device is in a slope position.
5.2.9.2.1.3 Where the curing injection machine or the lift-tilt device is fixed to the floor, overload conditions
to the loading components of the lift-tilt device shall be prevented in the event of the power operated loading
device meeting an obstacle. This can be achieved by fulfilling of one of the following conditions:
 slipping clutch;
 overload cut out (e.g. control limit switches with snap action and slow action contacts, and positive
contact opening) to stop automatically the lowering motion.
