Textile glass yarn breaking force, elongation tensile test
Date:2019-05-27 Source:United Test Views:100

The test is applicable to various types of glass yarn (single, folded, cabled, strands, structures without twist, rovings, etc.). It is basically intended for single, folded and cabled glass yarns having a diameter of less than 2 mm, or a linear density lower than 2000 tex, taken from packages.

Test Procedure:

tensile testing machine execute a constant rate of extension of 200 mm/min +- 20 mm/min. The machine shall be capable of stressing the sample until failure occurs. If the test machine has a pre-tensioning capability, a pre-tension force of 5 mN/tex +- 22.5 mN/tex shall be applied to the specimen. By means of our testing expertise and modular product design, we will help find the solution that is right for you. Give our test engineers a call today for help configuring the best test machine and accessories according to your standard.


Example of clamps from standard

Sample gauge length: 250~350mm.

For radius clamp fixture, radius r should between 12mm to 25mm for yarns linear density lower than 500 tex, radius r should between 25mm to 45mm for yarns linear density higher than 500 tex.
