Failure Investigation: Field Sampling and Communication to Maximize the Effectiveness of Laboratory Analysis

Failure Investigation: Field Sampling and Communication to Maximize the Effectiveness of Laboratory Analysis
Available for download

An accurate and comprehensive coating failure analysis often hinges not only on the quality of the field investigation and the laboratory analysis but also on effective communication between the field analyst and the forensic laboratory. Several steps can be taken during a field investigation to ensure that samples of coating removed for laboratory analysis fairly represent the condition of the coatings and give the forensic laboratory the best possible chance of discovering the root cause of the coating failure.

An accurate and comprehensive coating failure analysis often hinges not only on the quality of the field investigation and the laboratory analysis but also on effective communication between the field analyst and the forensic laboratory. Several steps can be taken during a field investigation to ensure that samples of coating removed for laboratory analysis fairly represent the condition of the coatings and give the forensic laboratory the best possible chance of discovering the root cause of the coating failure. The first step involves developing a sampling strategy. Among other considerations, the strategy involves the sampling of coatings in appropriate areas of failure as well as in areas where no failure has occurred coating. A second step involves the physical removal of coating samples to maximize the effectiveness of the subsequent laboratory examination. No single sampling technique is universally effective. Sampling techniques vary depending on the nature of coating failure, the physical condition of the coating (i.e., adhesion, thickness, hardness, etc.), the anticipated laboratory analytical technique, and the nature of the coated substrate. Effective communication between the field analyst and the laboratory analysts is critical. In most cases the decision on which laboratory analytical methods to employ depend on both the observations made during the failure analysis field investigation and on the preliminary microscopic examination of the coating samples. The observations made in the field and the microscopic observations are generally made by two different people with a differing understanding of the nature of the coating failure. Both the field analyst and a laboratory analyst must communicate their understanding of their observations to each other in order to develop an effective laboratory testing scheme.

This paper discusses a classic example where the facts surrounding the failure of a lining system were ignored and undue reliance was placed on laboratory analysis. This “blind faith” in analytical data without a sound causal theory caused the failure analysts to disregard or overlook the obvious.

Regardless of the sophistication of the laboratory, the ability to determine the cause of a coating failure can depend on the type and quality of the samples. This paper discusses the type of samples needed and gives suggestions on how to obtain them.
