    Table 4 and Table 5 of the standard showing Charpy Impact Requirements list limits for the absorbed energy with one digit to the right of the decimal point. A370 recommends and will in future require to round measured absorbed energies to whole numbers (no digit to the right of the decimal point). This may cause troubles for the evaluation whether a test result meets the requirements or not. It is proposed to revise the tables to show limits in whole numbers similar to A333 for the equivalent grades.
