1 Scope
This document specifies a method for evaluating depositions on real structures and
equipment by wiping. Depositions become corrosion and/or degradation factors for metals,
alloys and organic materials, and can be analysed quantitatively to control the corrosion
and degradation of real structures and equipment.
The method specified in this document is suitable for evaluating the type and amounts
of depositions on real structures and equipment in all industries. This method identifies
the type of depositions and gives instantaneous values of the concentrations of water-soluble
and insoluble depositions, which are expressed by mass per area without a time component.
These values provide information on environmental factors related to corrosion and
degradation. The method can be used to detect water-soluble depositions, including
chloride ion, sulfate ion and other ions, and can assist users in understanding the
synergistic and antagonistic effects that accelerate corrosion.
This document is applicable to:
metals and their alloys;
metallic coatings;
organic coatings;
concretes and other structural materials.
