Tensile Testing Device



This In House Test Method of Tensile Testing Device describes the method of test in order to determine the strength of attachment of press-studs (poppers) to textile materials used in garments.


The correct numbers of test specimens are to be prepared and tested as specified within this test method in order to achieve a performance assessment of the product/fabric as described within the scope.

A sample is taken from the garment, consisting of a sandwich of several fabric layers through which a press-stud (popper) has been applied. This is subjected to a known load, applied in such a way that the fabrics apply forces across the two halves of the press-stud component in opposing directions, thus tending to prise the two halves apart. Male and female halves of the press-stud (popper) are tested separately.


Tensile testing device of the constant rate of elongation type, capable of determining the applied load to ±5% accuracy at a rate of traverse 50 ±5mm/minute.Jaw width 50mm Gauge length Variable to suit test specimens being evaluated.


The test specimens are to be conditioned in the standard atmosphere of 65% Relative Humidity (RH) +/- 2% and 20°C +/- 2°C for a minimum of 4 hours. All tests should also be carried out in this atmosphere. Specification Force range: 10 ~ 1000N Test travel: 350 mm Sensing method: push pull meter Test speed: 5 ~ 300mm / min adjustable (can be customized) Power System: AC motor Volume: 560 × 345 × 1080 mm


Safety goggles must be worn.


Prepare the specimens as described in 5.2 such that the fabric strip has a maximum length and width (up to 200mm length and 50mm width), with one male, or one female, press-stud (popper) component positioned centrally within the width and as centrally as possible in the length direction. Testing press-stud/Fabrics removed from the garment. Cut a parallel strip of fabric from the garment that contains a single male, or female, press stud (popper) component such that:

  • The press-stud (popper) component is positioned centrally in the width of the fabric strip.
  • The width of the fabric strip is at least 20mm (up to a maximum of 50mm).
  • The press-stud component is positioned approximately centrally in the length-wise direction of the fabric strip.
  • The length of fabric on either side of the press-stud (popper) is between 25mm and 100mm. Note: Ensure that all four edges of the fabric strip have been cut. It may be necessary to separate the layers of fabric by cutting through lines of stitching.


  • Grip the test specimen in the jaw of the Tensile Testing Device in the manner shown in Diagram
  • Determine the force to remove the press-stud (popper) component.
  • Test a minimum of three male and three female components.

ASSESSMENT OF RESULTS:Ensure that comments as to how the components have broken down are reported.


  • The number of male and female press-stud (popper) components tested.
  • The average press-stud (popper) removal force for the male and female components separately.
  • Conclusion
  • The minimum press-stud (popper) removal force for the male and female components separately by Tensile Testing Device
