Summary
Tensile creep of 100 μm thick wood strips cut parallel to the grain was measured using a high resolution high accuracy creep apparatus. Rigorous attempts were made in both design and use of the apparatus to reduce errors to a minimum: the standard deviation of the random errors about a smoothed curve was assessed as 0.34 μm. By comparing elongation of strips under load with control strips at zero load viscous and visco-elastic elongation may be accurately measured.
