    7、ar forces to those in the test). The test is applicable to all types of ribbed insole, or to strips of insole material with ribs affixed along the edges. NOTESection4.6 is based on SATRA 1)Method AM 5. 2 Principle A force is applied to the lip of an attached insole rib, parallel to the insole surfac

    8、e and in the outward direction. The force is increased until failure occurs. 3 Supplementary information In the case of strips of insole material, the procedure described in this Section requires to be completed by information on the means of attaching the ribs to the insole material. This informati

    9、on shall be derived from the British Standard, or other specification, for the material under test or shall be the subject of agreement between parties interested in the results of the test. 4 Test pieces NOTEShear tests are usually combined with peel tests on the rib.Figure 1 andFigure 2 show conve

On each of two insoles, mark out two test pieces, each25mm wide, across the insole rib (seeFigure 1). 4.2 Insole material. (See also th

    11、e note to7.2.) Cut strips of material approximately75mm wide and350mm long. If the insole material has a direction marked for cutting out, cut one strip with its length in this direction. Otherwise, cut one strip in the machine direction and one strip in the cross direction. Attach ribs to the longe

    12、r edges of the strips, using the agreed method (see clause3). Mark out four test pieces,25mm wide, two on each longer edge as shown inFigure 2. 1) Shoe and Allied Trades Research Association Figure 1 Test piece layout for the determination both of the shear strength and the resistance to peeling of

Prepare each test piece by cutting along the parallel lines25mm apart, ensuring that each cut penetrates right through the rib and its stuck-down flanges into the insole. (It is unnecessary to detach the test pieces completely from the

    14、 remainder of the ribbed insole or insole material.) 5 Apparatus Use an apparatus, similar to that shown diagrammatically inFigure 3, embodying the following essential features (letters shown in brackets refer to the corresponding lettered parts ofFigure 3).

    16、le steel load beam (A) clamped rigidly at one end between cast iron bolsters (B), is measured by a gauge (C), calibrated to give a direct reading, in newtons, of the deflecting force applied at the free end of the beam. The device should show a full scale deflection of the load gauge for a shearing

    17、force of900N (90kgf). b) Rib clamp (D), attached to the end of the load beam, with jaws191mm wide. c) Pair of supports (F), fixed to the base of the device and providing a fulcrum for the insole clamp pivots(G). d) Insole clamp (H), fitted with clamping screw (J), pivots (G) and a lever handle (K) f

    18、or application, by hand, of the shearing force. The width of the clamp jaws shall be191mm. Clamp (H) shall be so positioned relative to clamp (D) that the force it exerts on test piece (E) is in the plane of the bond between the rib and insole material. NOTEOne suitable apparatus is the SATRA sole a

    19、dhesion tester (STD 185) fitted with attachments (STD 185/R) for shear strength testing. 6 Procedure Test each test piece by the following procedure. 6.1 Insert the rib of the prepared test piece fully into the rib clamp, positioning the section of rib symmetrically in the clamp, and tighten the cla

    20、mp whilst ensuring that the insole section of the test piece is vertical. Rotate the gauge dial to bring the pointer to “zero”. Slide the insole clamp into position along the insole until the clamp pivot rests on its support and the jaws are about2cm above the rib of the test piece. Tighten the inso

    21、le clamp firmly, making certain that the edge of the rib flange is not gripped. 6.2 Press down on the handle of the insole clamp so as to apply an increasing shearing force on the rib assembly, and to cause failure of the test piece in3s to4s. Record the force at failure and describe the type of fai

    22、lure occurring. NOTEFor a stuck-on rib of conventional design the most common types of failure can be described as follows: a) shear failure within the insole material; b) failure of adhesion to the insole; c) non-coalescence in the adhesive; d) failure of adhesion to the rib fabric; e) tearing of t

    23、he rib fabric (usually on the inside of the rib). 7 Expression of results 7.1 Ribbed insoles. Calculate the mean of the four results, i.e. the two results from each of the two sampled insoles. Express this mean, in newtons, as the shear strength. 7.2 Insole material. Calculate the mean of the four r

    24、esults for each direction of cutting of sample strips (see4.2). Express this mean, in newtons, as the shear strength for this direction. NOTEWith some cellulose boards, there may be a difference in results corresponding to the two directions along the length of the roll (i.e. usually at right angles

    25、 to the heel-toe direction of cut insoles). If this effect is apparent (either from the test results or the type of failure) then results for each of these two directions should be obtained and reported separately. 8 Test report Include the following items in the test report: a) the result expressed

    26、 in accordance with7.1 or7.2 as appropriate (the equivalent values in kgf may be added in brackets); b) the type(s) of failure occurring; c) nature and full identification of the sample(s); d) in cases where, for the purpose of the test, ribs were affixed to insole material strips, details of the me

    27、thod of attachment; e) reference to the method of test (i.e. Section4.6 of BS5131); f) date of testing.BS 5131-4.6: 1975 BSI 389 Chiswick High Road London W4 4AL BSIBritishStandardsInstitution BSI is the independent national body responsible for preparing BritishStandards.
