This Technical Specification gives test methods for prefabricated timber stairs. These stairs are made from timber and/or wood-based materials.The methods included in this document can also be used for single components used in stairs (e.g. steps, handrails, balusters, …).This document does not consider the overall structure design of these elements. Stairs that are designed to contribute to the overall stability of the works or to the strength of the structure are not covered by this standard.The surfaces of the timber elements may be exposed or covered by finishes.NOTE 1Where stairs are supplied with a finish or covering, some basic characteristics will not be covered by this standard and references should be made to the appropriate product standard (e.g. colour fastness of carpet finishes)NOTE 2Where the term "stair" is used in this document, it may also apply to individual element or component where appropriateTests can be carried out on a complete fully assembled system according to manufacturer installation instructions or on individual components.A fully assembled stair test cannot be used to evaluate individual components.There is no particular hierarchy of sequences or the need to carry out all the tests.NOTEThe nature of used tests and elements can be given by national regulations.
