21、-1. The extent to which hazards, hazardous situations and hazard results are covered is indicated in the scope of this standard. For machines which have been designed and built in accordance with the stipulations of this C type standard, the following applies: where C type standard stipulations devi
22、ate from respective stipulations in A or B type standards, the stipulations made in this C type standard take precedence over stipulations in the other standards. 1 Scope This European Standard applies to chests used in paper making and shall be applied together with !EN 1034-1:2000+A1:2010“. It dea
23、ls with all significant hazards, hazardous situations and hazard events relevant to chests when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). This European Standard does not apply to tanks for chemicals, storage tanks for starch and other additives u
24、sed in paper making or basins or vessels for waste water resulting from the paper making process. This European Standard does not apply to chests manufactured before the publication date of this European Standard. 2 Normative references The following referenced documents are indispensable for the ap
