4、iso.org ISO 13017:2012/Amd.1:2015(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body

5、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 ISO, also take part in the work. ISO collaborates closely with the International Electrotech

6、nical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO

7、documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

20、ng subclauses to the end of 6.3.1.2.2 ISO 2015 All rights reserved ISO 13017:2012/Amd.1:2015(E) 6.3.2 Materials 6.3 .2. 1 A dh e s i v e d o u b l e s i d e d ta p e , without any residual adhesive on the adhered face after the removal of the tape, for the temporary joining of the specimens and the

21、tables of the device during the alignment procedure. 6.3.2.2 Cyanoacrylate adhesive, for fixing specimens on the lower- and upper-tables. 6.3.2.3 Self-curing acrylic resin, for embedding a non disk-shaped specimen in the embedding ring with properties in accordance with ISO 14233:2003. 6.3.3 Fixing

22、procedure 6.3.3.1 Fixation of specimens Adjust the position of the lower-table equipped with the device (6.3.1.2) using the X-Y stage so that both centers of the lower- and upper-table are aligned. Attach the mating face of the magnet (or magnetic assembly) to the centre of the lower-table using an

23、adhesive double sided tape (6.3.2.1). Note that the side attached to the double sided tape will be the side that mates with the other magnet (or keeper) once the alignment procedure is completed. Place a drop of the cyanoacrylate adhesive (6.3.2.2) on the top of the magnet (or magnetic assembly) att

24、ached on the lower-table with the double sided tape, being careful not to let the glue flow down the sides of the magnet (or magnetic assembly). Move the upper-table down slowly until it makes contact with the magnet (or magnetic assembly) containing the drop of glue. If necessary, reinforce the bon

25、ding area between the magnetic (or magnetic assembly) and the upper-table with the self-curing acrylic resin (6.3.2.3). After the adhesive joining the magnet (or magnetic assembly) with the upper-table is set, move the table upward and remove the adhesive double sided tape (6.3.2.1), which was used

26、for alignment, from the mating face of the magnet (or magnetic assembly). Put the magnet (or keeper) on the mating face of the magnet (or magnetic assembly) that is now bonded to the upper-table. Make sure that the magnet (or keeper) is properly aligned with the magnet (or magnetic assembly). Place

27、a drop of the cyanoacrylate adhesive (6.3.2.2) at the centre of the lower-table. Move the upper-table down slowly until the bottom of the magnet (or keeper) makes contact with the lower-table containing the drop of glue. If necessary, reinforce the bonding area between the magnet (or keeper) and the

28、 lower-table with the self-curing acrylic resin (6.3.2.3). Dont move the lower- or upper-table until the adhesive joining the magnet (or keeper) with the lower-table is set. Also, to keep the proper alignment of the magnet (or magnetic assembly) on the upper-table with the magnet (or keeper) on the

29、lower-table, do not uninstall the lower- and upper-tables from the device (6.3.1.2) even after the adhesive is set.Page 5, Subclause 6.3.2 Replace the subclause number 6.3.2 Test procedure with 6.3.4 Test procedure. Replace the second sentence of first paragraph with the following: “Install the devi
