This standard test method was developed to address a number of testing parameters involved in the laboratory corrosion testing of clean metal test specimens in static chemical cleaning solutions at temperatures above boiling 100°C [212°F]}. Specifically, this standard addresses those parameters not covered in ASTM D 3263, including surface-to-volume ratio, inhibitor handling, localized corrosion and pitting, and the reporting procedure, and is for use specifically by those involved in the industrial cleaning industry. The intent is that these factors will make the reported corrosion rates more useful for comparing chemical cleaning solutions and inhibitors.

Because chemical cleaning solutions are used over a wide range of applications, no universal test method to cover all cases is possible. This standard is intended to be used to obtain data relevant to the cleaning of industrial equipment, such as boilers, heat exchangers, piping systems, and tanks. Note that these tests use clean test specimens in a clean solution and the severity of corrosion obtained in these tests will not be the same as if actual deposits were present.

This standard was prepared by NACE Task Group T-3M-5, a component of Unit Committee T-3M on Chemical and Mechanical Cleaning, and is published by NACE International under the auspices of Group Committee T-3 on Corrosion Science and Technology.

1.1 This standard describes a simple test method for measuring the relative corrosiveness of solutions used for chemical cleaning in a static system at temperatures greater than 100°C (212°F). The test described is conducted with corrosion test specimens in the clean condition (i.e., no deposits). The test consists of exposing metallic test specimens to cleaning solutions under controlled conditions in a test vessel. The test specimens are weighed before and after the test and the corrosion rate is calculated from the mass loss. Localized corrosion such as pitting is also evaluated.

Procedures for test specimen handling and reporting of test results for a better comparison of data among laboratories are also included.
