EN 13035-3:2003+A1:2009 (E) 4 0 Introduction This document is a type-C standard as stated in !EN ISO 12100-1". 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 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 1.1 This standard contains the requirements for safety for the design and installation of machines with one movable bridge for cutting of flat glass, which operate by scoring of the glass placed on a horizontal support.
This standard covers the transport of the glass on the machine. 1.2 !!!!This European Standard deals with all significant hazards, hazardous situations and events relevant to flat glass cutting machines, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards during commissioning, operation and maintenance." Hazards from noise are not considered to be significant. 1.3 This standard does not apply to flat glass cutting by abrasive cutting or by the use of high pressure liquid or lasers. 1.4 This standard does not apply to loading and unloading of flat glass on to or from cutting machines and the breaking out (see !EN 13035-5" and !EN 13035-6"). 1.5 This standard does not apply to conveyors (see EN 619) and fans as used as integral parts of the machinery.
If there are specific risks that arise in connection with flat glass cutting machines, appropriate measures are specified. 1.6 This standard does not apply to cutting of laminated glass (see !EN 13035-7"). 1.7 This standard does not apply to cutting while the glass is moving. 1.8 This document is not applicable to machinery which is manufactured before the date of publication of this document by CEN. 2 Normative references The following referenced documents are indispensable for the application of this document.
