Foreword
This document (EN 50636-2-94:2014) has been prepared by CLC/TC 116 "Safety of motor-operated
electric tools".
The following dates are fixed:

(dop) 2014-12-20
• latest date by which this document has to be
implemented
at national level by publication of an identical
national standard or by endorsement
(dow) 2016-09-30

with this document have to be withdrawn

– alignment to the European Machinery Directive 2006/42/EC;
– alignment to EN 60335-1:2012.
This document is to be used in conjunction with EN 60335-1:2012 “Household and similar electrical
appliances - Safety – Part 1: General requirements”.
When “Part 1” is mentioned in this standard, it refers to EN 60335-1:2012.
This document supplements or modifies the corresponding clauses in Part 1, so as to convert that
publication into the European Standard “Safety requirements for scissors type grass shears”.
Where a particular subclause of Part 1 is not mentioned in this document, that subclause applies as
far as is relevant. Where this standard states “addition”, “modification” or “replacement”, the relevant
text in Part 1 is to be adapted accordingly.
Compliance with the relevant clauses of Part 1 together with this Part 2 provides one means of
conforming to the specified essential health and safety requirements of the Directive.
This European Standard follows the overall requirements of EN ISO 12100.
Other harmonised standards referred to in this European Standard are listed in Annex ZC of Part 1
and this document. The annex lists the valid edition of those documents at the time of issue of this EN.
All references are however to be understood as references to the latest edition.
The following numbering system is used:
– subclauses that are numbered starting from 101 are additional to those in Part 1;
– additional annexes are lettered AA, BB, etc.;
NOTE In this European Standard the following print types are used:
- requirements proper: in roman type;
- test specifications: in italic type;
- explanatory matter: in smaller roman type.
Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the associated
noun are also in bold.
