TIS 166-2549 Figure A.7 Gauge for testing minimum withdrawal force
Product No: SC-TIS166-2549-FA.7-1 · SC-TIS166-2549-FA.7-2
Standard: TIS 166-2549 – Thai Industrial Standard for Plugs and Socket-Outlets for Household and Similar Purposes: Plugs and Socket-Outlets with Rated Voltage not Exceeding 250 V. Appendix A of the standard defines the gauges: Figures A.1 to A.5 check the dimensions of the socket-outlet, Figures A.6 and A.7 check the withdrawal force, and Figures A.8 to A.10 are the additional gauges for socket-outlets.
Application
The Figure A.7 gauge checks the minimum withdrawal force of a socket-outlet (TIS 166-2549, clause 22). The length of the gauge body is chosen so that the mass of the gauge itself equals the withdrawal force required by the standard.
The gauge is inserted into the socket-outlet with the engagement face in the most unfavourable position: it shall not come out of the socket-outlet under its own weight.
Two gauges are supplied so that both pole systems of the standard can be checked.
Construction
- Body and pin in corrosion-resistant stainless steel, as required by Figure A.7
- Body length chosen so that the gauge mass equals the withdrawal force specified in clause 22
- Supplied in pairs so that both pole systems can be checked
- Engraved with TIS 166-2549, Figure A.7 and the production number
