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.
