9. Timing circuit for sustained loading tests on PVA
adhesives
Describes tests for (1) the staining properties of the adhesive on wood; (2) the strength of double lap joints under three-point loading in shear, under dry and damp conditions; (3) the resistance of double lap joints to sustained three-point loading, under dry and damp conditions. A freeze-thaw treatment, designed as a preliminary to the strength tests, is included. Appendices to the standard cover the preparation of the test joints and a timing device for the sustained loading test.
