4 Safeguarding of significant hazards
4.1 General safeguarding requirements

Safeguarding shall be provided in those areas where it is recognized that operators are exposed to

significant hazards. The guarding requirements of ISO 12643-1:2021 apply. Guard construction shall

meet the requirements as specified in ISO 14120:2015. All manually-fed stand-alone platen presses

shall have trip bar(s) or other protective devices in accordance with 4.3 and located where access to a

hazard is possible.

The impact hazard created by the movable platen while opening shall be guarded by the use of an

interlocking knee bar (See Figure 1, Item 5). The length of the knee bar shall be equal to or greater than

the width of the movable platen. The knee bar shall be constructed such that it will retain its shape

to ensure actuation of the trip function throughout its length. With the movable platen in the open

position, the clearance between the knee bar and front surface of the movable platen shall be at least

120 mm. (See Figure 2, item 7).

On platen presses 1 m wide or larger presence detection shall detect anyone on the bed of the movable

platen and prevent start-up when the presence of a person is detected, and the press is stopped. Further

movement shall require the operation of a reset control and a separate manual restart.

Presence detection can be by means of a laser scanner(s), VBPD or another equally effective electro-

sensitive protection device(s). See Figure 8.

Individual beams may be muted as the platen stroke closes to prevent unnecessary stopping of the

operating cycle. If the presence detection device is provided as a means of detecting access to the platen

in accordance with 4.3, muting of beams shall not interfere with this function.

All mechanical trip bars shall be provided with a switch mounted on each end of the trip bar.

Trip functions using mechanical devices (including knee bars) shall satisfy the requirements of

ISO 13856-2:2013 and PL e of ISO 13849-1:2015 or SIL 3 of IEC 62061:2005. Trip functions or presence

sensing functions using laser scanners, vision based protective devices (VBPD) or light curtains shall

satisfy the requirements of PL d of ISO 13849-1:2015 or SIL 2 of IEC 62061:2005.

4.2 Safeguarding side access

Various means may be used to prevent access from the sides of the press. These include, but are not

limited to, the following:

a) Fixed protective barriers, interlocking guards and/or interlocking tables that prevent access, from

either side of the press according to Tables 2 and 4 of ISO 13857:2019. See Figure 2, Figure 3(a),

Figure 3(b) and Figure 3(c).

To prevent climbing onto the moveable platen, the following additional requirements apply to the

interlocking tables: The interlocking tables shall extend a minimum of 1 000 mm from the side

frame outward and over the depth of the platen press, reaching from the front edge of the open

position of the movable platen to at least 250 mm behind the backward edge of the fixed platen. See

Figure 2. The minimum height of the tables shall be 1 000 mm.

b) Laser scanners on both sides of the platen that shall meet the requirements as specified in

IEC 61496-1:2012 and IEC 61496-3:2013. See Figure 4.

The size and shape of the scanned areas on the sides shall be such as to detect and safely stop any

hazardous movements before the danger point(s) can be reached.”

Access between the scanned zones and the machine housing from the front and rear of the platen

press to the danger zones shall be prevented by fixed guards.
c) Vision Based Protective Devices (VBPD) in accordance with 4.5

Means of preventing access to the dangerous zone between the movable platen and the fixed platen

other than those defined at a) and b) shall provide an equivalent level of protection.

4.3 Safeguarding front access

For all manually-fed platen presses, a trip bar, located on the front edge of the movable platen, shall be

provided (see Figure 1 and Figure 2). The trip bar shall pass under the U-shaped trip bar in its operating

position with a clearance of 12 mm maximum.
One of the following configurations shall also be provided:

a) On platen presses less than 1 m wide an interlocking protective device (U-shaped trip bar) that

covers both the sides and the top of the fixed platen (see Figure 1). The mechanism of the U-shaped

trip bar shall be rated such that a force of 20 N applied to the top contact edge of the device is

sufficient for actuation and triggering of the clutch/brake device. The pivot of the U-shaped trip bar

shall be below the fixed platen. The horizontal part of the U-shaped trip bar shall be wide enough to

ensure that the leading edge of the trip bar is at least 300 mm away from the fixed platen. (see 4.8)

b) On platen presses 1 m wide or larger, laser scanners in accordance with 4.4;

c) On platen presses 1 m wide or larger, Vision Based Protective Devices (VBPD) in accordance with

4.5 (see Figure 5b).

d) On platen presses 1 m wide or larger, light beams or light curtains in accordance with 4.8..

The machine stroke shall be arrested to prevent crushing between the platens (see 4.7).

NOTE The u-shaped trip bar (interlocking guard) should be activated within 20 mm of movement measured

at the furthest point from the pivot point in order to initiate the position switches to stop the movement.

An opening between the top of the movable platen and the bottom of the top scanned area can be

provided to allow loading and unloading of work pieces. This aperture shall have a maximum height of

300 mm.
