This European Standard is a type C standard as stated in 6.3.2 of EN 1070:1998.
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.
Transfer and special purpose machines present a wide range of hazards due to the variety of processes and
configurations with possible obstructions to vision on these machines, in particular, those hazardous events
which result from contact with:
Moving tools especially when being rapidly rotated in spindles;
Fast moving machine parts;
Fast moving workpieces;
Power operated mechanisms for workpiece handling, load or unload.
The figures in annex C (informative) are examples only and are not intended to illustrate the only interpretation

machining operations and process parameters.
1.2 This standard takes account of intended use, including reasonably foreseeable misuse, maintenance,
cleaning, and setting operations. It specifies access arrangements to machining positions and manual
load/unload stations (see 3.4). It presumes access to the machine from all directions. It describes means to
reduce risks to operators and other exposed persons.
1.3 This standard also applies to transport devices for workpiece load/unload when they form an integral
part of the machine.
1.4 This standard deals with significant hazards relevant to transfer and special purpose machines when
they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). The safety
requirements and/or protective measures to prevent or minimise those hazards identified in Table 1 and
procedures for verification of these requirements or measures are found in clause 5. Safety requirements
and/or measures are not specified for: Fire and Explosion
1.5 Where machines employ processes which are covered by other standards (e.g. grinding, turning,
forming, EDM, laser processing), the requirements of those standards should be applied (see Bibliography).
1.6 This standard applies to machines which are manufactured after publication of this standard by CEN.
