Introduction
This European Standard is a type C standard as stated in EN 1070.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this standard.
This European Standard is intended to draw the attention of designers and manufacturers of tannery splitting and
bandknife shearing machines systematically to the relevant essential safety requirements and to suggest possible
solutions representing the state of the art of the profession with respect to safety.
1 Scope
This European Standard specifies safety requirements for design, construction, operation, adjustment, setting,
cleaning and maintenance of

splitting machines (see figures 1, 2) for limed hides and skins, wet blue and dry materials,

bandknife shearing machines (see figures 3, 4, 5, 6)
used in the splitting and shearing of leather and synthetic materials.
This standard takes account of intended use, foreseeable misuse, component and systems failure.
The machines are for fixed installation.
This European Standard applies to the machines manufactured after its date of issue.
All the significant hazards listed in clause 4 are safeguarded by the requirements included in clause 5 except dust
and fire.
For these hazards general guidelines are proposed in normative annex A.
Designers and manufacturers shall verify directly that the methods adopted to reduce these hazards have been
successful.
This standard does not establish any requirements for electromagnetic disturbances.
NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive
atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard
does not necessarily comply with Directive 94/9/EC. Additional safety requirements in a future revision of this standard can be
necessary to satisfy Directive 94/9/EC.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For
dated references, subsequent amendments to or revisions of any of these publications apply to this European
Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the
publication referred to applies (including amendments).

5 Safety requirements and/or measures
NOTE For hazards not covered by this European Standard which are to be reduced by the application of a B-standard
such as EN 292, EN 294, EN 418, EN 953, EN 60204-1 etc., a risk assessment is necessary to establish the requirements of
the B-standard to be applied. This specific risk assessment is part of the general risk assessment of the machine.
Machinery shall comply with the safety requirements and/or measures of this clause.
In addition, the machine shall be designed according to the principles of EN 292 for hazards relevant but not
significant which are not dealt with by this standard.
