Testing methods for GRP doors as per IS 4020- 1994 Fimen doors undergo following test
Dimensions and defects of square ness tests.
General Flatness tests.
Local plainness test
Impact indentation test
Edge Loading test
Shock resistance test
Buckling test.
Slamming test.
Screw holding power test.
Varying humidity test.
End immersion test.
Impact resistance (Shock resistance):
By conducting this test, Strength of the Door is checked.
Braking Strength:
Cross braking Strength of the laminate is tested at different points
Hardness:
Hardness of the laminate is tested using barcol impresser.
Tensile Strength:
Tensile strength of laminate is tested at different points.
