3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN ISO 12100:2010 and the following apply.
ISO and TEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http://www.electropedia.org/
— ISO online browsing platform: available at https://iso.org./obp
3.1
paper making and finishing machine
machine with which pulp or paper fibres are obtained, processed, joined together to form and also to finish paper, board, tissue and lIbreboard
3.2
paper converting machine
machine which are downstream of paper making and finishing machines
EXAMPLE cutting machines (guillotine cutters), corrugated board making and processing machines Note 1 to entry: Safety requirements for paper converting machines are dealt with in the EN 1010 series (EN ISO 12643 series).
3.3
machine section
functional unit of a paper making machine
EXAMPLE wire section, press section. dryer section, smoothing unit, coater, winding unit
3.4
crawl speed
speed as low as possible, but a set value of not more than 0,25 rn/s (15 rn/mm)
Note ito entry: For drives of machine groups (multi-motor drive/ sectional drives) applies: Variations caused by the process can lead to increases of up to 5 rn/mm for a maximum of 10 s (dynamic tolerance). Diameter changes
- e.g. from roll grinding - may require monitoring tolerances of up to 10 % or 1,5 m/min (static tolerance). These tolerances apply to the motor speed being monitored for safety purposes.
Note 2 to entry: The crawl speed may differ depending on the type of machine. Machine-specific deviations from the defined values are described in the subsequent parts of this standard.
3.5
hold-to-run control
operation of the machine by means of a hold-to-run control device as defined in EN ISO 12 100:2010,3.28.3
3.63
trapping point
danger point where the body or parts of the body, hair or clothing can get entangled
Note 1 to entry: Hazards due to trapping points may occur in situations when the body and parts 01 the body are entangled, but also in situations when the body does not have any chance to get free from a hazardous situation.
3.7
paper
material which include board, cardboard or tissue, essentially made of fibres of mostly vegetable origin and formed on wires (screens) by dewatering a fibre suspension
3.8
broke
scraps of paper, paper breaks and paper with imperfections
3.9
perimeter fence
distance guard preventing access to a hazard zone with a minimum height of 1,4 m and a clearance between floor and lower edge of the fence of 0,4 m maximum
Note ito entry: This definition does not relate to fall-off protections.
Note 2 to entry: When access is required, perimeter fences have doors that are electrically or mechanically interlocked, taking into account the access frequency, equipped with guard locking where required.
3.10
nip bar
guard arranged directly on the nip of a pair of rollers or some other nip
Note ito entry: For examples of nip bars, see Figure 3.
4 List of significant hazards
For a list of all the significant hazards as far as they are dealt with in this document, see Annex B, Table Bi.
5 Safety requirements and/or measures
5.1 General requirements and requirements for safety devices
5.1.1 Machinery shall comply with the safety requirements and/or protective measures/risk reduction measures of Clause 5. This Clause specifies the types of guards required for paper making and finishing machines,BS EN 1034-1 pdf download.
