4、 A comma is used as the decimal marker. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 145 “Plastics and rubber machines” (Secretariat: UNI, Italy). The responsible German body involved in its preparation was the Normenauss
5、chuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-60-10 AA Warmformmaschinen of Section Kunststoff- und Gummimaschinen. Representatives of manufacturers and users of thermoforming machines, and of the employers liability insurance associations contributed to t
6、his standard. This standard contains specifications meeting the essential requirements set out in Annex I of the new “Machinery Directive”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate
7、proof of compliance with the essential requirements of the directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive

36、12409:2011-12 EN 12409:2008+A1:2011 (E) 5 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standa
37、rd 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. DIN EN 12409:2011-12 EN 12409:
38、2008+A1:2011 (E) 6 1 Scope This European Standard deals with all significant hazards, hazardous situations and events relevant to thermoforming machines for continuous sheet and single sheets of thermoplastics materials, when they are used as intended and under conditions of misuse which are foresee
39、able by the manufacturer (see Clause 4). A thermoforming machine may consist of a forming unit or a forming unit linked to one or more additional units. This standard covers the following units: continuous sheet unwind unit; single sheet feed unit; material intake; conveying equipment; heating unit;
40、 preheating unit; edge heating unit; component feeding/inserting unit; forming station; finishing station; stacking station; discharge station; residual sheet winding unit; sheet cutting unit. This European standard does not apply to units mounted upstream or downstream of the thermoforming machine:
41、 which have a separate control system; and/or are located separately. NOTE 1 This European Standard specifies requirements for machines supplied as a single forming unit or a number of units designed to operate as a single machine. Additional units that may be introduced at a later stage should be c
42、onsidered separately applying relevant standards and taking into account any hazards arising through their interaction with the thermoforming machine. This European Standard does not apply to units which are integrated into form, fill and seal machines. These are covered in EN 415-3:1999. This Europ
43、ean standard does not apply to units which incorporate heating systems which are fuelled by gas. DIN EN 12409:2011-12 EN 12409:2008+A1:2011 (E) 7 NOTE 2 Thermoforming machines generally do not create explosive atmospheres. In principle they therefore correspond with line F of Table 2 of the ATEX Gui
44、deline and consequently do not fall within the scope of Directive 94/9/EC. This European Standard is not applicable to thermoforming machines which are manufactured before the date of its publication as EN. 2 Normative references The following referenced documents are indispensable for the applicati
