ASTM D2256 싱글 스트랜드법(Single Strand Method)을 사용한 실의 인장 특성
ASTM D2256 is a testing standard that specifies the method for determining the tensile properties of monofilament, multifilament, and spun yarns. It provides a testing procedure for determining maximum force and elongation and provides directions for calculating other properties such as breaking tenacity and modulus. ASTM D2256 is intended to determine the quality of the raw material while aiding in quality control of the finished product.
Materials Testing System
Due to its high data capture rate, we recommend our high tier 6800 Series test frame as the optimal solution for ASTM D2256 testing, although our more affordable 3400 Series is also appropriate. A single column frame is adequate for most single-strand yarn specimens as the loads rarely exceed 5 kN. In cases where yarn specimens require greater force, a dual column system may be needed.

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.

2714-005 Pneumatic Cord and Yarn Grips
Pneumatic cord and yarn grips provide a convenient method for clamping fiber, cord, yarns and fine wires to reduce the problem associated with testing these materials. Rated capacity 1 kN.
2714 Series Pneumatic Tire Cord Grips (2714-040)
Pneumatic cord and yarn grips are designed to have interchangeable clamping blocks that accommodate fiber or yarns made from conventional fibers to newly developed high-performance fibers. A specially designed horn with a smooth,highly-polished or controlled surface roughness finish and a contoured surface with
a graduated cam allows for easy loading and a stress-reduced clamping area on the specimen. The clamping mechanism can be activated either automatically or through a footswitch to allow hands-free grip operation; this enables the operator to hold the specimen with both hands for easy loading.
Pneumatic cord and yarn grips provide selectable clamping force to accommodate different materials and excellent follow up action that compensates for decay of the holding force due to specimen creep.
