21、 Uncontrolled Copy, (c) BSI Page 3 EN 1837:1999 BSI 12-1999 Introduction To illuminate visual tasks within and/or at machines integral lighting systems (built in or at machines) can be required. These integral lighting systems require special characteristics that allow both safe use and efficient pe
22、rformance of the visual task by the operator during operation and service. 1 Scope This standard specifies the parameters of integral lighting systems designed to provide illumination in and/or at both stationary and mobile machines to enable the safe use of the machine and the efficient performance
23、 of the visual task within and/or at the machine to be carried out. This standard does not specify lighting systems mounted on the machine to specifically illuminate visual tasks outside the machine. The function and requirements of these systems are specified in the European Standard dealing with t
24、he lighting of work places. This European Standard is under preparation. This standard does not establish additional requirements for the operation of lighting systems: in severe conditions (extreme environmental conditions such as freezer applications, high temperatures, etc.); subject to special r
25、ules (e.g.explosive atmospheres); where the transmittance is reduced by environmental conditions, such as smoke, splashing, etc. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the a
26、ppropriate places in the text and the publications are listed hereafter. For dated references, subsequent 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 pu

29、s of prEN 12665 apply. 3.1 machinery (machine) an assembly of linked parts or components, at least one of which moves, with the appropriate machine actuators, control and power circuits, etc., joined together for a specific application, in particular for the processing, treatment, moving or packagin
30、g of a material The term machinery also covers an assembly of machines which, in order to achieve one and the same end, are arranged and controlled so that they function as an integral whole. EN 1070:1998 3.2 integral lighting system (of a machine) a lighting system consisting of lamp(s), luminaire(
31、s) and associated mechanical and electrical control devices which forms a permanent part of the machine, designed to provide illumination in and/or at the machine 4 Lighting requirements 4.1 General When arranging the lighting for machines, ergonomic and lighting-engineering principles shall be take
32、n into account. The visual tasks to be carried out in and/or at the machine vary in size, contrast, position and speed of movement. Thus, for adequate vision, the exact lighting condition required shall be determined from detailed task analysis. The lighting requirements specified in this standard a
33、re based on average difficulty of visual tasks, found in the work space during operation or maintenance and servicing. For specific tasks, reference shall be made to the relevant standards on work place lighting (i.e. prEN 12464). 4.2 Illuminance The required illuminance depends upon the visual task
34、 and shall be sufficiently high and uniform as to enable a safe and comfortable perception of the details of the visual task. In general, a maintained illuminance of at least 500 lx shall be provided with a minimum uniformity (Emin/E) of 0,7 on the task area and 0,3 in the immediate surroundings of
35、the task. Where a visual aid or protective visor is required for use with the machine, the illuminance shall be multiplied by the reciprocal value of the transmitttance of this device. Where the transmittance is unknown the illuminance shall be increased by at least 50 %. In control cabins or where
36、processes are affected by light, the above illuminance may be reduced.

37、or and other workers in adjacent areas. Any reflected glare shall be avoided as far as possible. NOTEIt is possible to achieve this by suitable shielding of the lamp(s), by location and direction of the luminaire(s), and by the use of light, matt surface finishes. 4.4 Directionality The lighting sys
38、tem shall be designed and adjusted to avoid disturbing shadows on the visual task. The directionality of the lighting shall ensure a perception of form which is appropriate for the visual task. 4.5 Colour quality The colour rendering properties and colour appearance of the lamp(s) shall be suitable
39、for colour discrimination of the visual task and for operator comfort. 4.6 Stroboscopic effect The lighting system shall be designed to avoid stroboscopic effects which can lead to dangerous situations by changing the perceived motion of rotating or reciprocating machinery. NOTEThis can usually be a
40、chieved for example by use of d.c. electrical supply for incandescent lamps, or by operating incandescent or discharge lamps at high frequencies (around30kHz). 5 Lighting equipment and installation 5.1 Lamps Lamps shall be chosen to be safe in operation and not present a hazard to the machine operat
41、or. NOTEIt is advisable that in general, lamps are enclosed to protect the operator from injury caused by e.g. damaged lamps, excessive heat or emission of harmful radiation. 5.2 Luminaires Luminaires shall be designed to: a) provide the required lighting on the task; b) minimize the accumulation of
42、 dirt on lamps and optical surfaces; c) minimize premature ageing of optical elements; d) facilitate ease of service; e) comply with EN 60598; f) be compatible with the machine, for example withstand vibration, radiation, etc. 5.3 Installation Luminaires shall be mounted in such a way as to: a) prov
43、ide the required lighting on the task; b) avoid interference with the task and hazard to the operator; c) minimize the accumulation of dirt on lamp(s) and luminaire(s); d) facilitate ease of service. Examples showing the principles of some possible solutions are given in the informative annex A. 5.4
44、 Availability of illumination Where failure of the integral lighting system of the machine can give rise to dangerous conditions the lighting system shall consist of more than one light source. One of these sources shall be supplied from an alternative electrical supply. 5.5 Electrical supply The li
45、ghting system shall be connected to the electrical supply so that it is capable of operation even when the machine is switched off. 6 Verification procedures The manufacturer of the machine with integral lighting shall: a) measure the illuminance and check the uniformity (Emin/E) in the task area an
46、d the immediate surroundings. Illuminance should be measured with an illuminance-meter having a cosine and V(l) corrected photocell; b) check by visual inspection that glare control, directionality, colour properties and stroboscopic controls are satisfactory; c) provide a test report of the lightin
47、g system; d) supply a testing and maintenance schedule. 7 Information for use The performance of the lighting system shall be checked regularly, at least once a year, in accordance with 6d) and appropriate action shall be taken. The lighting system shall be cleaned and maintained as given in the mac
48、hines maintenance schedule in accordance with 6d).
