Introduction and Purpose
The purpose of these tests is to detect possible water, solid contaminants, microbial debris, surfactants and/or other petroleum products in aviation fuel by visual inspection. These tests are not precision tests; they are considered subjective. Experience is the important element; any condition that varies from the normal is a cause for concern. Questionable or unsatisfactory results obtained from these simple tests must be reported to your superiors and may require that certain specification tests must be performed to determine if the product is indeed on specification or not. These are the simplest tests, low cost and easy to run.
