If P is the failure load and D is the separation between the platens, the point load strength index (I s) is defined as IS = P D 2 (8.4) Corrections are applied to I S to allow for specimen size and shape to yield the size corrected point load strength index (I S50) which is defined as the value of I S for a diametral test with D equal to 50mm.Chat Online
