**For moisture meter correction, the comparison of the Gann moisture meter readings to actual oven tests, were tested for at least six different samples of floors typically reading 6-8% on the meter and then oven dried to 0% and use the data to develop the Gann adjustment factor.
**For shrinkage, the different wood was measured at their width and for moisture content and then they were dried to 0%. 3" flat sawn and straight grain flooring samples were used to develop the shrinkage coefficient in both straight grain and flat sawn flooring.
**Disclaimer: These results were obtained in a non affiliated testing lab and the results are based on the samples of wood tested. They may vary from other samples and from the same species growing elsewhere. Therefore, HAWA bamboo cannot assume any liability for your use of this data. These test results we taken from various sites and publications and cannot be documented by Hawa bamboo for their results.
