Two methods are specified: a) Measuring the electrical resistance or conductance of the test pieces using an electrical moisture meter and b) determining the loss in mass after drying test pieces until absolutely dry.
Abstract
Overview
ISO 4470:1981 is an international standard developed by the International Organization for Standardization (ISO) that specifies methods for determining the average moisture content of a lot of sawn timber. The moisture content of timber is a critical parameter affecting its quality, durability, and suitability for various applications. This standard outlines two practical and reliable methods of measurement: (a) using an electrical moisture meter and (b) the drying method involving mass loss determination. Both methods are designed to ensure consistent and accurate assessment of moisture content in homogeneous lots of sawn timber.
