ASTM D5035 Breaking Strength and Elongation of Textile Fabrics (Strip Method)
ASTM D5035 provides a testing procedure for determining the maximum force and elongation at maximum force of various textile fabrics using raveled strip and cut strip methods of testing. If required, the force and elongation at rupture are recorded as well.
The raveled testing method is mainly applicable to woven fabrics, whereas the cut strip test is mainly applicable to nonwoven, dipped or coated fabrics, and felted fabrics. However, the methods from this testing procedure are not meant for knitted fabrics or others with high breaking elongation. It is important to review the full standard in order to fully understand the test setup, procedure, and results requirements.
Materials Testing System
As with most textiles testing, it is important to consider data rate when choosing a testing instrument. To consistently and accurately measure the tear strength of your material, it is important to remember that the data sampling rate needs to be high enough that the test peaks and troughs are adequately captured. We recommend Instron’s high tier 6800 Series systems due to their data capture rate of up to 5 kHz. For most textile fabrics testing to ASTM D5035, a single column frame is appropriate as the loads rarely go above 5 kN.

TIPS AND TRICKS
- This standard recommends a Constant Rate of Extension (CRE) frame for testing, however, it also notes that Constant Rate of Load or Constant Rate of Traverse are acceptable as well. When different testing machines are used for testing the same materials, a constant time-to-break of 20 +/- 3 seconds is recommended for the most comparable results. It should be noted that results still can vary significantly based on the frame used.
- ASTM D5035 requires that two sets of specimens are prepared, one in the warp direction and one in the weft direction.
- Instron’s Bluehill Universal testing software has advanced pre-built methods available with pre-configured calculations helping to ensure compliance to ASTM D5035.
