BS EN 12409:2008+A1:2011EN 12409:2008+A1:2011 (E) 5 Introduction This document is a
30、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 standard are different from those which are stated in type A or B standards, the
31、 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. BS EN 12409:2008+A1:2011EN 12409:2008+A1:2011 (E) 6 1 Scope This European Standard deals with all signif
32、icant 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 foreseeable by the manufacturer (see Clause 4). A thermoforming machine may co
33、nsist 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; preheating unit; edge heating unit; component feeding/inserting unit;
34、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: which have a separate control system; and/or are located separately. N
35、OTE 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 considered separately applying relevant standards and taking into accoun
36、t 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 European standard does not apply to units which incorporate heating systems
37、which are fuelled by gas. BS EN 12409:2008+A1:2011EN 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 Guideline and consequently do not fall within the scope of Directive 94
38、/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 application of this document.
