The present work establishes a methodology in order to trueness and precision in the estimating the uncertainty of moisture content of wood. This is a requirement in the accreditation of the method for the determination of moisture content applying the ASTM D4442-2016 standard within the framework of ISO / IEC 17025- 2005, hence, ensuring the quality of the results issued by the laboratory. The estimated uncertainty for a moisture content of 12.03% was 1.12 % in the year 2018, which was reduced to 0.44 for the year 2019 through the adaptation of the methodology used and better conditioning of specimens. The sources of uncertainty associated with the measurement were bias, formula, and repeatability. It was found that the source that contributes more uncertainty was the one associated with the repeatability of the method, with a value of 0.57for the year 2018 and 0.21 for the year 2019, at the same moisture content of 12.03%
