Introduction
This document is a type-C-standard as stated in EN ISO 12100:2010.
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
above-mentioned 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);
— consumers (in the case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
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.
1 Scope
This document deals with all significant hazards, hazardous situations or hazardous events relevant to
derinding, skinning and membrane removal machines, when they are used as intended and under
conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex D).
This document deals with the hazards which can arise during all the lifetime of the machinery
(see EN ISO 12100:2010, 5.4).
This document is not applicable to derinding, skinning, and membrane removal machines for domestic
purposes, hand-guided machines and table-top machines.
This document is not applicable to fish heading and filleting machines as described in EN 15467:2014.
This document is not applicable to derinding, skinning and membrane removal machines manufactured
before the date of its publication.
