Foreword
This document (EN 1248:2001/prA1:2008) has been prepared by Technical Committee CEN/TC 202 “Foundry
machinery”, the secretariat of which is held by DIN.
This document is currently submitted to the Formal Vote.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this
document.
The new safety requirements as stated in this document comply with the additional relevant Essential
Requirements of the new Machinery Directive 2006/42/EC complementing the existing Machinery Directive
98/37/EC.
1 Modification to "Contents"
Add "Figures" and "Tables" at the end of the contents and update the table of contents:
Figures
Figure B.1 — Processing scheme with ….
Tables
Table 1 — Significant hazards, hazardous ….
2 Modification to "Foreword"
th
Replace the 4 paragraph with the following:
"For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral parts of this
document.".
3 Modification to "Introduction"
Replace the text of the clause "Introduction" with:
"This European Standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this European Standard.
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.
Where for clarity an example of a preventative measure is given in the text, this should not be considered as
the only possible solution. Other solutions can be used as far as they fulfil correctly the criteria expressed in
the requirement.
This European Standard assumes, that the equipment is operated and maintained by trained personnel.".
4 Modification to Clause "2 Normative references"
st
Replace the 1 paragraph with:
"The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced

7 Modification to "5.1 General"
Replace the sub-clause 5.1 with:
"5.1 General
5.1.1 Machinery shall comply with the safety requirements and/or protective measures formulated in Table

principles of EN ISO 12100-2 for relevant but not significant hazards which are not dealt with by this
document.
5.1.2 When selecting the adequate safety measures the manufacturer shall apply the following principles
in the given order:
1) elimination or minimisation of risks by integration of the safety concept into the design of the machine;
2) establishment of adequate safety measures against remaining risks (e.g. guard scaffolding, light barriers);
3) instruction to personnel concerning the remaining risks (e.g. service manuals, danger signs).
When more than one measure is necessary to safeguard a hazard then all the necessary measures shall be
used. When selecting the safety requirements and/or measures consideration shall be given to the different
hazards that may appear at the same time. Warning signs alone are not sufficient in cases of significant risk.
5.1.3 Where access is into a working area is by guards/doors the safety related parts of the electro-
mechanical/electronic control system shall be in accordance with at least performance level PL=d with use of
category 3 according to EN ISO 13849-1:2006. The hydraulic and pneumatic systems shall be in accordance
with at least performance level PL=c with use of category 1 accor
