GSO ISO 4470:2015 Scope
1.1 This International Standard specifies two methods for the determination of the average moisture content of a homogeneous lot of sawn timber of the same cross-section.
1.2 The method using an electrical moisture meter is applicable to timber having moisture contents from 7 to 28 % (m/m), and does not require cutting of the test pieces. The method cannot be used for determining the moisture content of frozen sawn timber.
If measuring the moisture content of sawn timber having a wet surface, due to water or to a surface protection treatment, the electrical moisture meter should be used with electrode needles that are covered, except for their tips, with an insulated coating.
1.3 The method by drying requires cutting of the test pieces. It is applicable irrespective of the moisture content, and is the only method applicable in cases of dispute.
