Laboratory Test to Evaluate the Vapor-Inhibiting Ability of Volatile Corrosion Inhibitor Materials for Temporary Protection of Ferrous Metal Surfaces


Volatile corrosion inhibitor (VCI) materials are widely used to provide temporary corrosion protection for the surfaces of ferrous and nonferrous metal parts. This standard test method evaluates the vapor-inhibiting ability (VIA) of various forms of VCI materials for temporary corrosion protection of ferrous metal surfaces, and is called the “VIA-Ferrous” test. It can be performed reproducibly with relatively simple and low-cost apparatus. The VIA-Ferrous test provides for standard conditions in a test jar of water-saturated, warm air without the presence of accelerating contaminants. This test method evaluates the combination of (1) vapor transport across a gap containing air, water vapor, and VCI, and (2) corrosion protection.
