The machinery concerned and the extent to which hazards, hazardous situation and events are covered are in
24、dicated 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 accord
25、ing 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 pipe prestressing machines as defined in Clause 3. With the aim of clarifying the intentions of the document it should be noticed
26、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 equipment will only be used by competent and designated persons, t
27、he place of use/installation is adequately lit, all operations are carried out by specially trained operators.“ BS EN 12629-5-3:2003+A1:2010EN 12629-5-3:2003+A1:2010 (E) 5 1 Scope 1.1 !This part of EN 12629, taken together with EN 12629-1:2000+A1:2010, applies to pipe prestressing machines as define
