TIS 166-2549 Figure A.10 Gauge for testing minimum withdrawal force of current-carrying pole for flat-round pin socket-outlet
Product No: SC-TIS166-2549-FA.10
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.10 gauge checks the minimum withdrawal force of the current-carrying pole of a flat-round pin socket-outlet (TIS 166-2549, clause 22).
The length of the gauge body is chosen so that sufficient weight is obtained within a height of 50 mm. The gauge is inserted in one current-carrying opening and shall not come out of the socket-outlet under its own weight, with the socket-outlet placed in the most unfavourable position.
The drawing in the standard expresses the dimensions and the construction of the gauge only.
Construction
- Body and pin in corrosion-resistant stainless steel, as required by Figure A.10
- Pin profile matched to the current-carrying opening of the flat-round pin socket-outlet
- Body length giving sufficient weight within a height of 50 mm
- Engraved with TIS 166-2549, Figure A.10 and the production number
