Impact energy, equivalent mass and drop height table
| Energy/J | 2 | 5 | 10 | 20 | 50 |
| Equivalent mass /kg | 0.5 | 1.7 | 5 | 5 | 10 |
| Drop height ±1%mm | 400 | 300 | 200 | 400 | 500 |
| Notes: 1. See note in IEC 60068-2-75 3.2.2 1. In this part, the energy (J) is calculated taking the standard acceleration due to the earth’s gravity(g), rounded up to the nearest whole number, that is 10m/s². |

| 1) 85≤HRR≤100, Rockwell hardness according to ISO2039-2. 2) Fe490-2, according to ISO1052; Rockwell hardness according to ISO6508. |
| NOTE- The values shown in the brackets for the equivalent mass and the diameter of the striking elements for the energy value equal to or less than 1 J are those in the current test Ef. The values currently in test Eg are also shown for these two parameters. For co-ordination purpose, the values in brackets will be deleted fives years from the publication of this standard. |
