ASTM D2256 单纱法测量纱线的拉伸性能
TIPS AND TRICKS
- ASTM D2256 is available as a pre-built test method within Bluehill Universal software. This method includes pre-configured calculations to help expedite test setup and simplify the testing process.
- This standard recommends a Constant Rate of Extension (CRE) test frame for operating at a 20 second time-to-break, paired with grips that provide adequate clamping throughout testing. If the frame cannot provide a 20 second time-to-break or the grips allow for slippage while testing, the standard allows for alternative testing methods. These alternatives will likely be dependent on each yarn’s material properties.
