The strength and stretch variables of careful gloves are significant for its quality and execution. Tensile testing of careful gloves is proceeded according to the global norms of ASTM D412 for its acknowledgment around the world. The normalization guarantees that the careful glove won’t tear or come up short, and has adequate stretch. Allow us to examine the utilization of tensile test in various industries, explicitly for careful gloves.

Ideal tensile testing – ASTM D412
ASTM D412 is one of the worldwide principles which work under ASTM International. Under this norm, careful glove material is tested for its tensile pressure (or strain,) tensile strength, yield point and ideal stretching.

The ‘test technique A’ for tensile testing of clinical gloves are as per the following:
1.Cut a sample from the glove material in a ‘free weight’ shape.
2.Set the example inside the grasps firmly and guarantee no slippage ought to be there.
3.Stretch it from one or the flip side by an ASTM D412 normalized tensile testing machine at a steady speed until it breaks.
4.There should be a PC on the machine which can gather the information live while the test is on.
5.Once the example breaks, its stretching will be determined and recorded.

The tensile test can be rehashed for those examples which have been gone through the ‘quickened maturing cycle’s in warming chambers according to ASTM D573.

This test analyzes glove’s actual properties for its whole timeframe of realistic usability which is typically a ‘uncommon case’ situation. On the off chance that the gloves are appropriately put away in a cool and dry spot, avoided daylight, warmth, and stickiness, it will show a preferred strength and stretching over the ‘post-maturing’ tested examples.

Tensile strength necessity:

  • The least required tensile strength for latex gloves = 18 MPa (before its maturing)
  • The least required tensile strength for latex gloves = 14 MPa (post-maturing)
  • The least tensile strength for nitrile gloves = 14 MPa (when maturing) Stretching necessity:
  • The least required stretching for latex gloves = 650% (prior to maturing)
  • The least required stretching for latex gloves = 500% (in the wake of maturing)
  • The least required lengthening for Nitrile gloves = 500% (prior to maturing)
  • The least required lengthening for Nitrile gloves = 400% (in the wake of maturing)


  • What significance do the test results have while choosing and wearing gloves?
    It’s not generally the situation that high tensile strength is needed for clinical gloves. The most noteworthy number doesn’t really signify ‘best execution’. Glove producers should keep a harmony between strength, stretch, and solace. Too high tensile strength can once in a while make the glove unbending or hard to wear.

    Lengthening is a significant factor to pass judgment on the presentation of glove. High lengthening makes the glove stretch instead of tearing. A glove with great prolongation number will stretch and fit by the hand, improving the solace and quality.

    Utilization of tensile testing machine is constantly needed in various industries including clinical firms. Consequently it is critical to get the procedure and instrument right.
