The Short Span tester is an advanced instrument which yields the national and international standard such as ISO, Tappi, and SCAN etc. The short span compression tester also reduces the factor which gives variation; Tester also reduces loading and unfavorable stress. It also avoids these factors giving result which have a material property unaffected by density and gram mage. The accuracy and repeatability of test result depends on the correct sample conditioning. The internal programming provided the rapid means of setting up the instruments. The facilities such as Peak hold at max load auto return after the completion of that test.
A test specimen, 15 mm wide is clamped in pneumatically operated two clamps, 0.7 mm (0.0276 in.) apart.
The clamps are forced towards each other until a compressive failure occurs. The maximum force causing failure is measured.
