26、N 12629-4:2001+A1:2010 (E) 4 Introduction !This European Standard is a Type C-standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situation and events are covered are indicated in the scope of this document. When provisions of this type C document a

27、re 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. This document specifies the addit

28、ional requirements to and/or the deviations from EN 12629-1:2000+A1:2010 specific for the concrete roof tile making machines as described in 1.1. With the aim of clarifying the intentions of the document it should be noticed that the following assumptions were made when producing it: specific condit

29、ions of use or environmental conditions out of the scope of the document shall be the subject of negotiations between the manufacturer and the user/owner, the equipment will only be used by competent and designated persons, the place of use/installation is adequately lit, all operations are carried

30、out by specially trained operators.“ 1 Scope ! 1.1 This part of EN 12629, taken together with EN 12629-1:2000+A1:2010, applies to concrete roof tile making machines. EN 12629-1:2000+A1:2010 specifies general requirements applicable to machines for the manufacture of constructional products from conc

31、rete and calciumsilicate. This document specifies the additional requirements to and/or the deviations from EN 12629-1:2000+A1:2010 specific to the machines it covers.“ 1.2 Limits of the machine The tile making machine is considered to begin at the point where moulds and/or the concrete are delivere

32、d to the fixed part of the machine and ends after the tile cutting process where products on their moulds are delivered on to an outfeed conveyor (see Annexes A and B). Moulds and concrete may be delivered to and removed from the machine by hand. The preparation of the concrete mixture and the trans

33、port from the mixer to the machine are not covered by this standard. The equipment for the transport and handling of formed products is not covered by this standard. BS EN 12629-4:2001+A1:2010EN 12629-4:2001+A1:2010 (E) 5 ! 1.3 This European Standard deals with all significant hazards pertinent to t

34、hese machines, including the interfaces, when they are used as intended and under 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 the significant ha

35、zards. This standard establishes safety requirements and/or methods of protection which applies to these machines.“ ! 1.4 This document is not applicable to concrete roof tile making machines, which are manufactured before the date of publication of this document by CEN.“ 2 Normative references !The
