24、 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 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

25、 the other documents, for machines that have been designed and built according to the provisions of this type C document. This document specifies the additional requirements to and/or the deviations from EN 12629-1:2000+A1:2010 specific for the block making machines as described in 1.1. With the aim

26、 of clarifying the intentions of the document it should be noticed that the following assumptions were made when producing it: specific conditions 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

27、 equipment will only be used by competent and designated persons, the place of use/installation is adequately lit, all operations are carried 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 machines for the manufacture

28、of blocks, kerbs, paving stones and similar concrete products. EN 12629-1:2000+A1:2010 specifies general requirements applicable to machines for the manufacture of constructional products from concrete and calciumsilicate. This document specifies the additional requirements to and/or the deviations

29、from EN 12629-1:2000+A1:2010 specific to the machines it covers.“ 1.2 !This European Standard deals with all significant hazards pertinent to these machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This Europe

30、an Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.“ 1.3 This European Standard applies to the machines from the point at which the mixture enters the machine (see point 1-2 of annex B) and the point where the pallet boards are

31、brought to the assembly (see point 3 of annex B) until the point where the green products are removed from the machine assembly to the curing system (see point 4 of annex B). !deleted text“ BS EN 12629-2:2002+A1:2010EN 12629-2:2002+A1:2010 (E) 5 !1.4“ This European Standard deals with the hazards !d
