Requirements for the fit of parts in various details of joinery.

This Part of BS 1186 specifies requirements for the fit of parts in various details of joinery, and indicates a degree of care to be exercised in the forming of joints and the application of adhesives.

The suitability and selection of joints for specific applications are not included in this Part of BS 1186.

This Part of BS 1186 does not apply to wood trim.

Guidance on machined surfaces and their treatment and on timber movement are given in Appendix A and Appendix B respectively. Methods of test for the assessment of finger joint strength are given in Appendix C.
