WebRecord the dial gauge reading, and the proving ring reading every thirty seconds up to a strain of 6%. The reading may be taken after every 60 seconds for a strain between 6%, 12% and every 2minutes or so beyond 12%. Continue the test until failure surfaces have clearly developed or until an axial strain of 20% is reached.
WebDec 30, 2015 · PROVING RING CONSTANT. Your graph should start at the origin of the two axes. If you have zero load, you have zero deflection of the proving ring. Add load in consistent increments. For example, if you expect a total load of "X" then do increments of 0.1X. This should give you a reasonable plot of load vs. deflection of the proving ring.
