The test specimen shall be 127mm in length(L). 13mm in height(h) and 6.35mm in width(b). Dimensions of the specimen are determined by the mean value of two measurements in the center area for the width and a measurement in the center area for the depth. The test shall basically be made on the specified test specimen without any special compensation. In case the dimensions of the test specimen are different from the specification, the dimensions of the specimen shall be measured and the load shall be compensated accordingly as shown below so that the correct heat deflection temperature can be measured.
