GTR9-9-06 Proposed amendments of the three-point bending certification test figure Current : When performing certification tests according to the figure, the ground and knee makes contact. Contact Current figure Actual Test
GTR9-9-06 Proposed amendments of the three-point bending certification test figure Proposal : Instructions for setting up the spacer to prevent contact have been added to the figure.
