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of an identical text or by endorsement, at the latest by January 2010, and conflicting national standards shall be withdrawn at the latest by January 2010. This document includes Amendment 1, approved by CEN on 2009-06-05. This document supersedes EN 13042-2:2004. The start and finish of text introduced or altered by amendment is indicated in the text by tags
!". 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 EC Directive(s). It is one of a series concerning machinery for the treatment and processing of hollow glass. !For relationship with EC Directive(s), see informative Annexes ZA and ZB, which are integral parts of this document." According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 13042-2:2004+A1:2009 (E) 4 0 Introduction This document is a type C document 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 document are different from those which are stated in type A or B documents, the provisions of this type C document take precedence over the provisions of the other documents for machines that have been designed and built according to the provisions of this type C document. Handling machines for the feeding of melted glass are independent mechanical devices working in one or more axes to pick up melted glass from the (working) bowl of (melting) furnaces, e. g. by winding up the high-viscous melt on ball-shaped receivers (ball-feeders) or by sucking up into gathering containers (suction feeders). The handling machines transport the gathered post off melted glass to the forming machine or to the glass blower's place and deposit it there. Noise is not a significant hazard. Noise emitted by air-cooling devices of machinery linked to the handling machine for feeding may be so high that there is a need for the operator of the handling machine to wear ear protection. When compiling this document, it was assumed that: state of the art requires an interference in the motion path of the handling machine by the operator especially during the first cycles of the forming machine to be supplied; adequate lighting is provided.

1 Scope 1.1 This document contains the requirements for safety for the design and installation of stationary handling machines for feeding from the taking up of a post of melted glass out of the working bowl of a glass melting furnace through transport to delivery to a glass blower or to a forming machine for hollow glass. 1.2 !This European Standard deals with all significant hazards, hazardous situations and events relevant to handling machines for feeding, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from significant hazards during commissioning, operation and maintenance." 1.3 !This European Standard does not deal with the exclusive feeding with shears alone, with the transport of the melted glass post by its own weight in free fall or by trueing (gob feeder, see EN 13042-1)." 1.4 This document is not applicable to handling machines for feeding which are 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.
