There are no publications that deal with impact resistance specifically in respect of plasterboard, however there are sections within British Standards (see below) that deal with aspects of this. Health Technical memorandum 56 has design and specification guidance for the strength and stability of partitions (within health buildings) – this relates to the requirements of BS5234: Part 2, and covers aspects of impact resistance required.
The British Standards that are most relevant to aspects of impact resistance including the use of plasterboards and associated products are as follows:
BS5234: Partitions (including matching linings).
Part 1: 1992 Code of practice for design and installations.
Part 2: 1992 Specification for performance requirements for strength and robustness including methods.
BS5588: Part 5: 1991 Code of practice for firefighting stairs and lifts.
BS8000: Part 8: 1994 Code of practice for plasterboard partitions and drylinings.
BS8212: Part 1: 1995 Code of practice for dry lining and partitioning using gypsum plasterboard.
