Nondestructive determination of spruce lumber wood density using drilling resistance (Resistograph) method
Open accessAbstract
The use of Resistograph for the purpose of nondestructive evaluation of certain properties of standing trees and wooden materials has increased in recent years. The resistance to penetration of a fine drill bit is measured and recorded by the device. A number of properties of the wood can be assessed by the amplitude values obtained from the Resistograph. The aim of this study was to assess the utility of the IML-Resistograph F 500 as a nondestructive tool for estimating spruce wood density using the amplitude data generated and the application of statistical modeling. Wood density data were determined using a volumetric method and were compared with the density data generated by the model. In this model, amplitude was used as an independent variable and the dependent variable for experimental purposes was wood density. No statistical difference (P = 0.176 > 0.05; 95% confidence level) was found between the groups. Moisture content was added as second independent variable and a second model was built. The results demonstrated that wood density can be estimated nondestructively using Resistograph data from lumber and/or large wooden materials, but more comprehensive models are required for the practical use of the device in the forest products industry.

When density was estimated using the Resistograph in new timber, R2 and StE are usually higher than in recovered timber.
“When density was estimated using the Resistograph in new timber, R 2 and StE are usually higher than in recovered timber as shown in several studies.”

The Results and discussion (p. 5) report that Resistograph data can predict spruce lumber density, and Table 3a (p. 6) gives an R² and a standard error of estimate for one model. The paper does not compare new with recovered timber or establish that either statistic is usually higher in new timber. (LLM, conf=0.82)

The relationship between drilling resistance and wood density is influenced by various factors, including tree species and the device itself. It is important, therefore, that the Resistograph be calibrated for the species of interest.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
