Representatives of manufacturers and users of blade granulators, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set

32、ncerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over th
33、e provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. DIN EN 12012-1:2010-02 EN 12012-1:2007+A1:2008 (E) 6 1 Scope This document specifies the essential safety requirements applicable to the design and construction of
34、 blade granulators used to reduce objects and materials made from plastics and rubber into granules. The machine begins with the outer edge of the feed opening, or feeding device if it is an integral part of the machine, and ends with the discharge area. Only the significant hazards listed in clause
35、 4 and dealt with in clause 5 are subject to this document. This document does not deal with hazards caused by processing harmful materials. This document is not applicable to machines which are manufactured before the date of its publication as an EN. 2 Normative references The following referenced
