ASTM D4444-92(1998)e1
Historical Standard: ASTM D4444-92(1998)e1 Standard Test Methods for Use and Calibration of Hand-Held Moisture Meters
SUPERSEDED (see Active link, below)
ASTM D4444
1. Scope
1.1 These test methods apply to the measurement of moisture content of solid wood, including veneer, and wood products containing additives, that is, chemicals or adhesives (subject to conditions in 6.4 and 9.4). They also provide guidelines for meter use and calibration by manufacturers and users as alternatives to ovendry measurements.
1.2 Conductance and dielectric meters are not necessarily equivalent in their readings under the same conditions. When these test methods are referenced, it is assumed that either type of meter is acceptable unless otherwise specified. Both types of meters are to be calibrated with respect to moisture content on an oven-dry mass basis as determined by Test Methods D4442.
1.3 The method title indicates the procedures and uses for each type of meter:
Section Method A Conductance Meters 5 to 7 Method B Dielectric Meters 8 to 101.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
