This European Standard specifies the test method to be used in determining the racking strength and stiffness of timber frame wall panels. The test method is intended primarily for panels as described, to provide: - comparative performance values for the materials used in the manufacture of the panels, and - data information for use in structural design. The principle of the test method is suited to other sizes and shapes of panels and to other methods of hold down as well as panels which are partially sheathed and to combinations of panels. NOTE – The method is detailed for a general situation where the client for the test knows the materials to be used in the construction, which may cover a range of different panels and walls and therefore wishes to test a standard configuration of panel. Where specific details are fixed they may be incorporated into the test but any additions or changes to the standard configuration are indicated in the test report and, later, can lead to limitations on the use of the test data.
