BS EN 12629-8:2002+A1:2010EN 12629-8:2002+A1:2010 (E) 4 Introduction !This European Standard is a Type C-standard as stated in EN ISO 12100. The machinery concerned and the exte
26、nt 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 the
27、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 machines and equipment for the manufacture of constructional
28、 products from calcium silicate (and concrete) 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 conditions of use or environmental conditions out of the scope of the document shall
29、 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 out by specially trained operators.“ 1 Scope 1.1 !This part of EN 12629, taken
30、 together with EN 12629-1:2000+A1:2010 applies to hydraulic machines for the manufacture of bricks, blocs and elements of calcium-silicate (as illustrated in Annexes A and B). NOTE Calcium-silicate can be replaced by concrete. EN 12629-1:2000+A1:2010 specifies general requirements applicable to mach
31、ines for the manufacture of constructional products from concrete 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 !This European Standard deals with all significant hazards pertine
32、nt 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 European Standard specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards. Noise hazard
33、 and vibration hazard are considered as not significant for those machines.“ BS EN 12629-8:2002+A1:2010EN 12629-8:2002+A1:2010 (E) 5 1.3 This European Standard applies to the machines from the point at which the mixture enters the machine (see point 1 at annex A, B) until the point where the green p
34、roducts are removed from the machine to the curing system (see point 2 of annex A, B). !deleted text“ 1.4 !This document is not applicable to machines and equipment for the manufacture of constructional products from calcium silicate (and concrete), which are manufactured before the date of publicat
