Dimensions, mm For Test Specimens with Gauge Length Four times the Diameter (E8]. Test specimens made from powder metallurgy (P/M) materials are exempt from this requirement by industrywide agreement to keep the pressing of the material to a specific.ĪHM E8/E8M – 13a. The gauge length is the most significant difference between E8 and E8M test specimens. Dimensions, mm For Test Specimens with Gauge Length Four times the Diameter (E8.
