3 Terms and definitions
Add, after term and Definition 3.9, the following new term and definition:
3.10
small equipment
equipment, either positioned on a table top or standing on the floor which, including its cables
fits in a cylindrical test volume of 1,2 m in diameter and 1,5 m above the ground plane
