26、ic stainless steel complying with ISO7153-1 or other materials providing the instrument made therefrom meets the requirements of clause6. 5.2 Material of handle The material of the handle, selected at the discretion of the manufacturer, shall meet the requirements of clause6. 6 Requirements 6.1 Surf
27、ace finish 6.1.1 All surfaces All surfaces shall be visibly free from pores, crevices, grinding marks, residual scales, acid, grease and residual grinding and polishing materials, when inspected using normal vision. 6.1.2 Satin finish Satin finish shall be both uniform and smooth, and it shall reduc
28、e glare. 6.1.3 Mirror finish Mirror finish shall be ground to remove all surface imperfections and polished to remove grind marks, resulting in a highly reflective surface. 6.2 Vickers hardness of working end The Vickers hardness of the finished instrument, when tested in accordance with ISO6507-2,
29、shall be within the range of class1 or class2. The manufacturer shall state the appropriate(hardness) class for each instrument pattern or range of instruments in the documentation. 6.3 Resistance against corrosion When tested in accordance with7.2 or7.3, there shall be no visible signs of corrosion
30、. With the exception of serrated martensitic stainless steel handles, any blemish shall be considered as evidence of corrosion. 6.4 Resistance against thermal exposure When tested in accordance with7.4, there shall be no alteration of its physical appearance. The Vickers hardness after thermal expos
31、ure shall still be within the stipulated hardness range. 6.5 Union of working end and handle The union between the working end and the handle of the instrument, previously tested in accordance with7.1, shall not become loosened under tensile load when tested in accordance with7.5.1 and under torque
32、when tested in accordance with7.5.2. 6.6 Design and dimensions The instrument shall have the design and dimensions specified in the appropriate part ofISO13397.

After completion of the tests rub the instrument(s) vigorously with a cloth to remove any blemishes. 7.2 Autoclave test Carry out the autoclave test a
34、s specified in ISO13402. 7.3 Boiling water test Carry out the boiling water test as specified inISO13402. 7.4 Thermal test Carry out the thermal test as specified in ISO13402. 7.5 Test for union of working end and handle 7.5.1 Test under tensile load Subject the union between the working end and the
35、 handle to a tensile force of600N, applied in the direction parallel to the centreline of the handle, for a duration of at least5s. 7.5.2 Test under torque Subject the union between the working end and the handle to a torque of400Ncm for a duration of at least5s.ENISO13397-1:1995 BSI 01-2000 5 Annex
36、 A (informative) Measurement of dimensions A.1 General This method of measurement is applicable to most types of dental hand instrument and is based on the use of an optical projector. Dimensions are measured parallel, and at right angles, to the centreline of the instrument and are constructed from
37、 a datum point at its working end. Although this is the preferred method, it is by no means the only technique available. A.2 Apparatus A.2.1 Optical projector (shadowgraph) fitted with 10 magnifying lens and micrometer stage. A.2.2 Glass specimen slide and plasticine, or A.2.3 Mechanical holding de
38、vice (e.g.light machine vice), or A.2.4 V-block A.3 Procedure A.3.1 Preparation for measurement A.3.1.1 Support or hold the dental instrument using one of the devices inA.2.2, A.2.3 orA.2.4. A.3.1.2 Place the supported instrument on the micrometer stage of the projector(A.2.1) and ensure that the fo
39、llowing requirements are met: a) the working end of the instrument projects beyond the holding device; b) the instrument is securely held; c) there is an unobstructed view of the working end. A.3.1.3 Ensure that the dental instrument is parallel to the micrometer stage by focussing on, and traversin
40、g the length of, the handle. If the handle remains in focus over the traversed distance, then the instrument is ready for measurement. If the handle does not remain in focus, repeatA.3.1.2 andA.3.1.3 until the handle remains in focus through the field of traverse. A.3.1.4 Align the centreline of the
41、 dental instrument with the vertical and horizontal cross-wires on the projector screen. A.3.2 Horizontal and vertical measurements A.3.2.1 Refer to the illustration, table of dimensions and table of measurement points related to the instrument to be measured and, using the micrometer stage, bring t
42、he appropriate point of the projected image to either the vertical or horizontal cross-wire, whichever is appropriate to the datum measuring point of interest. A.3.2.2 Zero the micrometer and move the micrometer stage to the final measurement position and record the measurement. A.3.2.3 Realign the
43、instrument(A.3.1.4) and repeat stepsA.3.2.1 andA.3.2.2 for the remaining dimensions. A.3.3 Angular measurements A.3.3.1 Refer to the illustration, table of dimensions and table of measurement points related to the instrument to be measured and, using the micrometer stage, bring the appropriate point
44、 of the projected image to either the vertical or horizontal cross-wire, whichever is appropriate. A.3.3.2 Rotate the bezel of the projector screen to the datum measuring point and note the angular reading. A.3.3.3 Rotate the bezel to the final measurement position, subtract the initial angular read
45、ing from the final reading and record the measured angle.ENISO13397-1:1995 6 BSI 01-2000 Annex ZA (normative) Normative references to international publications with their relevant European publications This European Standard incorporates by dated or undated reference, provisions from other publicat
