ASTM A370 고강력 철근의 인장 및 굽힘시험 (Rebar)
인장시험에는 불규칙한 철근의 표면에 발생할 수 있는 미끄러짐을 줄여주기 위한 초기 파지력 때문에 유압식 웨지그립이 사용된다. 이 유압식 웨지그립은 직경 10 mm (0.39 in)에서 70 mm (2.75 in)까지의 철근을 잡을 수 있다. 그립 죠(grip jaw)는 V자 형태로 되어있으며 철근의 표면의 립부분(rib)을 위한 맞춤형 홈이 가공되어 있다.
마지막으로 연신율 측정을 위하여 자동 신율계(automatic extensometer)가 사용된다. M300B 모델은 표점거리를 10 mm에서 300 mm (대부분의 철근 시험에 요구됨)까지 조절이 가능하다. 이 자동 신율계는 시험이 시작되면 철근 시편 표면에 자동으로 장착되고 시험 중 지정한 지점에서 자동으로 벌어지도록 되어있다. 연신율 데이터는 탄성계수(modulus)와 항복점(yield calculations) 계산 등에 사용된다.
Industrial Series Brochure
The trend toward high-strength, lightweight materials for the aerospace, energy, construction, and transportation industries requires materials testing systems to be durable, yet maintain precise control while generating critical test data. Software user interfaces must be easy to use, yet flexible enough to meet the increasing demands of the testing world. The Industrial Series delivers exceptional performance packaged in reliable, innovative system designs that offer superior accuracy and repeatability, improved safety, and an overall enhanced user experience.
