When requirements of this type-C-standard are different from those which are stated in type-A- or type-
B-standards, the requirements of this type-C-standard take precedence over the requirements of the
other standards for machines that have been designed and built according to the requirements of this
type-C standard.
1 Scope
This document specifies safety and hygiene requirements of clipping machines (hereafter referred to as
machine) for closing of casings filled with foodstuffs (hereafter referred to as product) by a clip deformed
by a closing tool, and which are intended to be used in butcheries, meat processing factories, main
kitchens and other food processing factories.
This document deals with all significant hazards, hazardous situations and hazardous events relevant to
machinery when it is used as intended and under conditions of misuse which are reasonably foreseeable
by the manufacturer (see Annex D).
This document does not cover any devices whose clip is exclusively formed manually.
This document is not applicable to clipping machines manufactured before the date of its publication.

3.2 Descriptions
This clause describes the types of clipping machines, semi-automatic machine (see Figure 1 and Figure 2)
and automatic machines (see Figure 3).
Clipping machines are used to close casings with a single clip (one side) or a double clip (end locking and
start locking).
The machines are equipped with a closure tool, which creates the closure by deforming the clip.
On semi-automatic machines every closure operation is triggered by the action of an operator.
An automatic machine, once started, performs each further closure operation without manual
intervention or start command.

Clipping machines shall comply with the safety requirements and/or protective measures of this clause.
In addition, the machine shall be designed according to the principles of the EN ISO 12100:2010, Clause 4,
for relevant but not significant hazards which are not dealt with by this document (e.g. sharp edges).
The interlocking devices associated with guards shall at least comply with EN ISO 14119:2013 Type 1,
and shall not be positioned in the food area (e.g. inside the machine housing or another housing).
Machines safety functions are implemented and ensured through Safety-Related Parts of the Control

— a movable tunnel-shaped cover. Depending on the height H of the outlet opening, the length L of the
tunnel-shaped cover (see Figure 12) shall correspond to the values of Table 3. The actuating force
for lifting the guard shall be ≤ 50 N. The tunnel-shaped cover shall be interlocked (see 4.1) to stop
the machine if the tunnel-shaped cover has been moved by ≤ 20 mm out of the closed position, and
the required performance level PL of the safety-related parts of the control system shall present at
r
least a performance level “c” according to EN ISO 13849-1:2015;
— a fixed tunnel-shaped cover. Depending on the height H of the outlet opening, the length L of the
tunnel-shaped cover (see Figure 12) shall correspond to the values of Table 4.
Openings, except the outlet opening, in the tunnel-shaped cover and distances to neighbouring
constructional elements (e.g. chute, conveyor) shall correspond to EN ISO 13857:2019, Table 4.
