The work of preparing Intern

16、ational Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with

17、 ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical

18、 committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to

19、the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

33、N ISO 15752:2010ISO 15752:2010(E) ISO 2010 All rights reserved 34.2 Retinal protection If the time to reach the aphakic weighted retinal radiant maximum exposure guideline is 30 min at maximum output, a retinal protection means shall be installed in the instrument to increase the time to W 30 min. T

34、he status of the protection means, whether enabled or disabled, shall be clearly evident to the user during surgery. 4.3 Stability of light intensity The endoilluminator light source shall be designed to ensure that, when operated at maximum output, differences in output due to ageing, maintenance,

35、servicing and correctly rated lamp and component replacements cannot reduce the time and/or number of pulses necessary to reach the maximum exposure guideline below the level determined in accordance with ISO 15004-2:2007, 6.5. This shall be applicable throughout the lifetime of the endoilluminator

36、light source when maintained in accordance with the manufacturers specifications. Among other methods, this may be achieved by a risk management process. 5 Test methods 5.1 Determination of irradiance, spectral irradiance and spectrally weighted irradiance for Group 1 and Group 2 instruments For end

37、oilluminators that produce a uniform beam on the retina, with a diameter greater than 1 mm at the recommended use distance, the following shall apply. For the determination of irradiance or spectrally weighted irradiance for standard/collimated light guides, the maximum radiant power or spectrally w

38、eighted radiant power for each light source at maximum intensity shall be determined over an averaging area of 1 mm in diameter at a distance of 15 mm from the exit aperture. For the determination of irradiance or spectrally weighted irradiance for wide-angle/diffusing and chandelier light guides, t

39、he maximum radiant power or spectrally weighted radiant power for each light source at maximum intensity shall be determined over an averaging area of 1 mm in diameter at a distance of 18 mm from the exit aperture. For the determination of irradiance or spectrally weighted irradiance for pic/forceps

40、 light guides, the maximum radiant power or spectrally weighted radiant power for each light source at maximum intensity shall be determined over an averaging area of 1 mm in diameter at a distance of 1 mm from the tip that is intended to be in contact with the macula. A measurement aperture equal t

41、o the diameter of the gauge of the endoilluminator shall be used for endoilluminators that produce a uniform beam on the retina with a diameter of less than 1 mm at the recommended use distance. Where the distance of use is not as specified above, measurements shall be made at the distance specified

42、 by the manufacturer. Measurements shall be made in water or a saline solution. The spectrally weighted retinal irradiance at maximum intensity is equivalent to the value of the maximum spectrally weighted radiant power in a 1 mm diameter area divided by the area (7,9 103cm2). For endoilluminators t

43、hat do not produce a uniform beam on the retina at the recommended use distance, a measurement aperture of 0,03 mm shall be used. BS EN ISO 15752:2010ISO 15752:2010(E) 4 ISO 2010 All rights reserved5.2 Determination of half-angle The output divergence half-angle shall be determined to be the angle a

44、t which the irradiance is equal to one half of the maximum irradiance when evaluated through a 1 mm aperture. The uncertainty in the angle shall be less than 1. A measurement aperture equal to the diameter of the gauge of the endoilluminator shall be used for endoilluminators that produce a uniform

45、beam on the retina with a diameter of less than 1 mm at the recommended use distance. For endoilluminators that do not produce a uniform beam on the retina at the recommended use distance, a measurement aperture of 0,03 mm shall be used. 5.3 Measurements to classify instruments in Group 1 or Group 2

46、 In order to classify instruments in Group 1 or Group 2, 5.1 and 5.2 of this International Standard shall apply, together with ISO 15004-2:2007, 6.1, 6.2 and 6.4. 5.4 Group 2 instrument measurements For Group 2 instrument measurements, 5.1 and 5.2 of this International Standard shall apply, together

47、 with ISO 15004-2:2007, 6.1, 6.3, 6.4, 6.5.1 and 6.5.2. 6 Information supplied by the manufacturer 6.1 General For endoilluminators classified as Group 2, ISO 15004-2:2007, Clause 7, shall apply. 6.2 Information supplied by the manufacturer of Group 2 combination of endoilluminator light source and

48、light guides 6.2.1 Manufacturers of combination endoilluminator light source and light guides shall provide the user with the exposure time(s) required to reach the aphakic weighted safety guideline with the endoilluminator light source set at maximum intensity and 50 % of maximum intensity, with an

These guidelines shall be provided either on the endoilluminator light source or in/on the packaging of each light guide. An example of information to be provided is given in Annex A. 6.2.2 The manufacturer of the endoilluminator light source shall provide the user, upon request, with a graph showing the relative spectral output of the endoilluminator between 320 nm and 1 100 nm, with and without the retinal protection means, when the
