Each assembly is provided with ready to
use connections fittings. Test rig is designed to accurately
determine specimen stress requirements. Test specimen size
5mm-6mm, width 15-25mm, and with length of 150mm is suitable for
testing four point bending specimens. Stress corrosion specimen
is smoothly machined before putting in the test jig.
Four point bend test jig comes with
digital deflection meter attachment to measure accurate
deflection. 4-point bend test jigs are fabricated from
precision-machined stainless steel with high accuracy. Stress
level can be easily adjusted using a workshop wrench on the
tension-adjusting screw and lock nut. Four- point bends provide
a uniform tensile stress over a relatively large area of the
specimen
Test vessel with standard environment
chamber is machined from clear, durable perspect / acrylic to
permit instant visual observation of the specimen at all times.
Glass with acrylic vessels is also available at option of user.
O-ring seals are provided to prevent any leakages from test
vessel. Individual test vessels are tested with Hydrotest of air
before dispatch. At a time maximum 8-10 sets of samples can be
tested. This depends on thickness of material.
In the test vessel, solution of sodium
chloride+ acetic acid or synthetic ocean sea water as per ASTM
D1141 is used with known pH.
Samples are stressed as per ASTM G39
specifications and immersed in the solution for the test
period.
At the end of the test, samples are
evaluated for cracks using magnetic particle inspection or
standard metallographic test and pH of the test
solution.
