ASTM D6775 Break Strength and Elongation Test Equipment for Textile Webbing, Tape and Braided Material
This test method covers the determination of the breaking strength and elongation of textile webbing, tape and braided materials using a split-drum type specimen clamp.
This test method is limited to materials with a maximum width of 90 mm(3.5in.) and a maximum breaking strength of no more than 89000N(20000lb).
Equipment Required:
1.Tensile Testing Machine, CRE-type, conforming to Specification D76 with respect to force indication, working range, capacity and verification of recorded elongation, and designed for operation at a pulling speed of 75±25mm/min(3±1in./min).
2.Clamping Assembly, consisting of an upper and lower clamp, each a split-drum type, as shown in Fig.1 and Fig.2.
3.Computer or Microprocessor, interfaced, with auto-matic data gathering system, including photo or electronic instruments to measure elongation.(Optional).
