European foreword
This document (EN 1539:2015) has been prepared by Technical Committee CEN/TC 271 “Surface
treatment equipment - Safety”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2016, and conflicting national standards shall be
withdrawn at the latest by April 2016.
This document supersedes EN 1539:2009.
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 the EU Directive
2006/42/EC.
For relationship with the EU Directive, see informative Annex ZA, which is an integral part of this
document.
This European Standard is part of a series of standards in the area of safety for development and
construction of machines and plants for the coating of surfaces with organic substances (paints,
lacquers and similar products).
This European Standard was prepared with contribution of the following TCs:
— TC 186 "Industrial thermoprocessing - Safety";
— TC 198 "Printing and paper machinery - Safety";
— TC 200 "Tannery machinery - Safety";
— TC 202 "Foundry machinery".
NOTE 1 Although a dryer as a whole is not subject to the ATEX Directive 94/9/EC in a formal way, this
document is based on a fundamental risk assessment according to this Directive.
NOTE 2 This European Standard is based on an explosion protection concept which does not define zones for
areas with potentially explosive atmosphere.
In relation to the previous version of the standard, the following main modifications have been made
— the scope has been adjusted to meet the fields of application of the standard;
— the requirements for safety related controls have been modified for clarification;
— guidance for implementation of safety related control systems has been included;
— requirements for monitoring of heating system have been implemented;
— requirements for type B dryers have been detailed;
— requirements for minimization of energy usage and environmental impact have been included.

Introduction
This document is a type C standard as stated in EN ISO 12100.
This document is of relevance in particular for the following stakeholder group representing the market
players with regard to machinery safety:
— machinery manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organisations, market surveillance).
The machinery concerned and the extent to which hazards, hazardous situations and hazardous 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.

1 Scope
This European Standard deals with all significant hazards, hazardous situations and hazardous events
relevant to ovens and dryers in which flammable substances are released by evaporation from and
curing of coating materials.
The specific significant risks related to the use of this machinery with foodstuff and pharmaceutical
products are not dealt with in this European Standard.
This European Standard is only applicable to machines which are used as intended and under the
conditions which are foreseeable as malfunction by the manufacturer (see Clause 4).
For ovens and dryers in which flammable substances are released by evaporation from and curing of
coating materials, in which the concentration of these flammable substances shall not, under no
circumstances, exceed 3 % of the LEL, EN 746-1 and EN 746-2 may be applied instead of this European
Standard.
This European Standard is not applicable to:
— ovens for hardening metals;
— enamelling plants;
— portable heating systems for drying (for instance infrared radiant heaters, hot-air blowers, blow-
dryers);
— solvent recovery plants;
— distillation and/or refraction plants;
— textile dry-cleaning systems.
This European Standard is not applicable to machinery manufactured before the date of its publication
as EN.
