25、ed in !EN ISO 12100“. The extent to which hazards are covered is indicated in the scope of this standard. In addition, machinery shall comply as appropriate with !EN ISO 12100“ for hazards which are not covered by this standard. 1 Scope This European standard specifies safety requirements relating t
26、o the design and construction of multi-roll calenders intended for the processing of rubber or plastics. This standard concerns the calender alone including all components fixed to its frame. Annex A shows examples of various types of calenders and annex B shows examples of calendaring processes. Th
27、e following machines are excluded: two-roll calenders forming an integral unit with an extruder (roller head); two or three-roll polishing , laminating or embossing units (which are not calenders) installed downstream of extruders in film processing lines. This standard deals with the significant ha
28、zards listed in clause 4. The following hazards are not dealt with: hazards generated by the materials being processed (see informative annex C); hazards generated by the processing of explosive materials, or materials which give rise to an explosive atmosphere; fire hazards due to ignition of flamm
29、able materials by contact with hot parts of the calender (e.g. in case of oil leakage); hazards due to electromagnetic, laser or ionising radiation; hazards generated if the calender is installed in an explosive atmosphere. This standard applies to machinery manufactured after the date of approval o
30、f this standard by CEN. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent
31、 amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies. !deleted text“ BS EN 12301:2000+A1:2008EN 12301:2000+A1:2008 (E) 5 EN 294:
