Precision and Bias11.1 No precision and bias statement can be made for testmethod 7.2, bending force test, since a controlled round-robintest program has not been run at this time. A controlledround-robin test program is not considered feasible due to theunique nature of th
49、e testing apparatus. No information can bepresented on the bias of the test procedure in test method 7.2,bending force test, because no material having an acceptedreference value is available.12.
