I am Currently Working on Measuring Various Mechanical Properties of Metalic Materials using Universal Testing Machine (UTM) at Various Temperatures. I know that for Testing at Ambient Conditions, ASTM E8/E8M is followed.
By Literature Review, I have Identified the Specimen Dimensions for My Experiments.
Due to Lack of Adequate Experimental Data, I am Unable to Identify the Specimen Dimensions with respect to ASTM E21 and ISO 15579 for Testing at Elevated and Low Temperatures respectively.
Since, These Standards are Quite Costly to be Purchased Individually, Should I take the Specimen Dimensions at Room Temperature for Experiments at Low and High Temperatures ?
Is there a Major Difference in the Dimensions presented by these Standards or Can I Complete the Analysis using My Assumptions ?
