BS 5234 Part 2

Duty Ratings

BS 5234: Part 2 comprises a series of tests which examine a partition systems' suitability for a given partition duty. Each test method is specific for the duty grade required and has strict acceptance criteria.

The test methods are:

 

  • Partition Stiffness -a point load is applied to the partition and the maximum deflection together with any residual damage recorded.
  • Hard body impacts - two levels of impact are applied to the partition firstly to assess the resistance
    to damage of the partition lining and the second to assess the resistance to perforation.
  • Soft Body Impact - two levels of impact are applied the first to assess the resistance to aesthetic
    damage and the second to assess the resistance to structural damage.
  • Door slamming- a door built within the partition system is mechanically slammed and the
    deformation and damage on the partition system assessed.

The standard also includes optional test methods, which are not included in the duty grading
system. These are:

  • Crowd Pressure - a line load is applied to the partition and the partitions ability to resist the load
    assessed.
  • Heavyweight anchorages - wall cupboard and wash basin
  • Lightweight anchorages - pull out and pull down

It is possible to perform a full duty rating, or undertake individual annexes as required; please contact our Structures department for a quote or further information.
