FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

19.101.3.1 Straight work
19.101.3.1.1 Fence dimension
In order to ensure the vertical stability of the workpiece, the single spindle vertical moulder
shall be equipped with fences which:
– have a minimum height greater than the usable spindle length;
– have a minimum length of
• the table length (for both fences), or
• 300 mm (for each fence),
whichever is the smaller.
Compliance is checked by inspection and by measurement.

19.101.3.1.2 Fence adjustment
The fence assembly shall be capable of being fixed securely to the table and shall be adjustable
to take account of the cutting tool diameter and the position of the spindle.
When transverse adjustments are carried out, the fence plates shall remain integral with their
supports.
The lateral adjustment of the fence plates shall allow any necessary opening for the cutting tool
to be reduced to a minimum. The fence plates shall either be fitted with a device ensuring
continuity between the fence plates or shall be equipped with fixing arrangements which would
permit such a device (e.g. false fence) to be fitted.
A fine adjustment control for transverse movement of the outfeed fence plate with respect to
the infeed fence plate shall be provided. When moved in this way, the fence plate shall remain
parallel to the fixed fence plate and their re-alignment shall be checked using a method given
by the manufacturer in the instruction manual (see 8.14.2 b) 107)).
All adjustments shall be capable of being undertaken without the aid of a tool.
The part of the fence plates close to the cutting tool shall be made of light alloy, plastic or wood.
Compliance is checked by inspection.
19.101.3.2 Curved work
A workpiece guiding device suitable for curved work, see Figure 109, shall be provided and
consist of either
– a guiding steady (ring guide)
• the shape or adjustment of which shall allow a progressive penetration of the cutting tool
into the workpiece;
• that supports and guides the workpiece during working;
• that shall have the tangential point where the depth of cut is measured clearly marked;
• the adjustment range of which shall take account of all possible positions of the cutting
tool with respect to the table; and
• that during adjustment shall remain parallel to the table within 0,5 mm over a length of
100 mm
or
– a lead-in device which allows the use of a ball ring guide
• that allows progressive feed of the workpiece to the cutting tool;
• where the tool has two directions of spindle rotation, shall be designed to allow for its
use whichever direction of rotation is selected; and
• where the guard supporting device is designed to allow for the fixing of a guiding steady
and the lead-in device is also capable of being fixed to the supporting device, shall be
capable of being moved out of position whilst remaining integral with the workpiece
guiding device to allow for the use of the guiding steady.
Compliance is checked by inspection and by measurement.
