ASTM, (2002), "G84-89(1999)e1 standard practice for measurement of time-of-wetness on surfaces exposed to wetting conditions as in atmospheric corrosion testing", ASTM International, West Conshohocken, PA.
Abstract:
1. Scope

1.1 This practice covers a technique for monitoring time-of-wetness (TOW) on surfaces exposed to cyclic atmospheric conditions which produce depositions of moisture.

1.2 The practice is also applicable for detecting and monitoring condensation within a wall or roof assembly and in test apparatus.

1.3 Exposure site calibration or characterization can be significantly enhanced if TOW is measured for comparison with other sites, particularly if this data is used in conjunction with other site-specific instrumentation techniques.

1.4 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.
