Introduction
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
abovementioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
The above-mentioned stakeholder groups have been given the possibility to participate in the process of
drafting this document.
This document is a type-C standard as stated in ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are
covered are indicated in the Scope of this document.
When requirements of this type-C standard are different from those which are stated in type-A or type-B
standards, the requirements of this type-C standard take precedence over the requirements of the other
standards for machines that have been designed and built according to the requirements of this type-C
standard.
The full set of requirements for machines in the scope of this document are those given in this document
EN 415-4 applicable to that type, together with the relevant requirements from EN 415-10:2014.
As far as possible in EN 415-4 safety requirements are referenced to the relevant clauses of
EN 415-10:2014 to avoid repetition and reduce their length.
EN 415-10:2014 applies when this document does not provide requirements.
Therefore, this document EN 415-4 is intended to be used in conjunction with EN 415-10:2014.
When a requirement of EN 415-4 differs from a requirement of EN 415-10:2014, the requirement of
EN 415-4 will prevail.
When a machine covered by EN 415-4 incorporates functions described by other standards of the EN 415
series, those functions are expected to comply with those standards.
EXAMPLE 1 In the case of a palletizer which incorporates cartooning mechanisms, the palletizing mechanisms
are expected to comply with EN 415-4 and the cartoning mechanisms are expected to comply with
EN 415-7:2006+A1:2008.
EXAMPLE 2 In the case of a palletizer which incorporates a pallet wrapping mechanism, the palletizing
mechanisms are expected to comply with EN 415-4 and the pallet wrapping mechanisms are expected to comply
with EN 415-6.
Annex ZA of this document will not list the EHSR of Annex I of the Machinery Directive which are
completely covered by EN 415-10:2014.
Annex ZA of this document will not list the EHSR which are not relevant for this kind of machines or are
not covered for any other reason.
