Visual Test

Last updated: July 16, 2019

What Does Visual Test Mean?

A visual test refers to the close examination of a material's surface (often a metallic surface) to determine its state of wear and/or the presence of corrosion based only on what can be seen and crossed-referenced with governing inspection standards.

Visual testing is typically the first type of test performed to determine corrosion infiltration. It is conducted in an environment with ample lighting and with reference to support publications to facilitate the proper identification of observed discrepancies.

A visual test may also be known as a visual inspection.

Corrosionpedia Explains Visual Test

Standard references such as ASTM International, ASME and ANSI are all crossed-referenced to draw finite conclusions of visually observed occurrences. Video cameras can be used to record observations for reference purposes. Visual testing is often followed by chemical or biological testing to make conclusive decisions.
