TIS166-2549 Figure A.9 Flat-Round Pin Max Withdrawal Force Gauge

GNGPL-TIS166FA9 TIS166-2549 Fig A.9 Test Gauge is manufactured in accordance with Thai Standard TIS 166-2549 Appendix A, Clause 22, specially for maximum withdrawal force test of flat-round pin socket-outlets. Additional weights can be mounted at 50 mm height to apply pulling load, testing the ultimate clamping capacity of socket contact sleeves and preventing safety hazards such as loose plugs, poor contact and overheating. It is the designated test fixture for flat-round pin Thai socket-outlets for TIS safety certification. The gauge is made of non-corrosive stainless steel, all dimensions comply strictly with tolerances specified in the standard drawing.

Specifications:
• Compliance Standard: TIS 166-2549 Appendix A, Figure A.9, Clause 22
• Applicable Sample: Flat-round pin socket-outlets
• Material: Stainless steel (non-corrosive metal)
• Dimensions: Fully comply with all millimeter dimensions and tolerances on drawing
• Structure Feature: Reserved position for additional weights at 50 mm height
• Function: Maximum withdrawal force test for flat-round pin socket-outlets

Test Procedures:
• Insert the gauge smoothly and fully into the flat-round pin socket-outlet.
• Mount additional weights gradually at the specified 50 mm height as required by standard.
• Record the load when the gauge separates from the socket as the maximum withdrawal force.
• Compare measured data with standard limits to judge the qualification of socket clamping performance.
• Repeat the full test on all socket positions of the sample.

Applications:
• Pre-compliance testing for Thailand flat-round pin socket-outlets applying for TIS 166-2549 certification
• R&D clamping force verification and factory outgoing inspection for flat-round pin Thai standard socket-outlets
• Third-party electrical safety testing laboratories
• Compliance verification of ultimate clamping performance for flat-round pin socket contact sleeves
• Mitigate risks including loose plugs, power interruption and thermal ignition
