18、rolled Copy, (c) BSI EN 13827:2003 (E) 4 1 Scope This European Standard specifies methods for the determination of the mean lateral displacement between cords, and for the determination of the vertical displacement of cords relative to a mean level of steel cords within a conveyor belt as described
19、in prEN ISO 15236-1. 2 Normative references Not applicable. 3 Method A. Determination of cord pitch and supported belt width 3.1 Apparatus NOTEIf there are other measuring tools with the same or better precision these can also be used. 3.1.1Measuring tape, graduated in divisions of 1,0 mm. 3.1.2Hand
20、 held optical magnifier, incorporating a scale graduated in divisions of 0,1 mm and having a magnification of not less than x8. 3.1.3Dial gauge micrometer, graduated in divisions of 0,1 mm. 3.1.4Flat horizontal surface to support the full width of the conveyor belt. 3.2 Test piece The test piece sha
21、ll be of full belt width and not less than 50 mm long. The cut edges shall be smooth, free of contamination and shall expose the cords clearly. If the cut edges are not smooth enough the test piece can be prepared in a different way so that the position of the cords can be measured with a precision
22、given in this European Standard. 3.3 Procedure 3.3.1Determination of mean cord pitch (tm) Using the measuring tape (3.1.1), measure the distance to the nearest 1,0 mm between the outer edges of the first and last cord across the width of the test piece (see Figure 1), and record this value as (bt +
23、d). Alternatively, use the measuring tape to measure the belt width to the nearest 1,0 mm and measure the thickness of the edge rubber, bk, at both edges to the nearest 0,5 mm; (bt + d) is the belt width less edge rubber thickness. Using the micrometer (3.1.3), or the hand held optical magnifier (3.
24、1.2), measure the diameter of either the first or the last cord in the test piece to the nearest 0,1 mm and record the value as (d). Count the total number of cords across the width of the test piece and record the number as (n). Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 11:10:23 GMT+00
