This standard defines procedures to measure in laboratory the impact sound level reduction of isolated heavy landings connected to a heavy wall, isolated heavy flights of stairs connected to a heavy landing, floor or ceiling, and lightweight stairs connected to a heavy wall, floor or ceiling. This standard also considers the characterization of isolating elements for heavy landings or heavy flights of stairs in terms of an insertion loss expressed as an impact sound level difference. The corresponding procedure is given in a normative annex (Annex A), separated from the other procedures for the sake of clarity.
