NACE Resources
Use and Misuse of Laboratory Tests Laboratory corrosion tests are used in many ways. They can provide a simple basis for comparing the severity of corrosion of two or more materials in a simple standardized way. Laboratory testing can also be a convenient means for closely simulating service environments to obtain useful information for materials selection. Finally, laboratory corrosion tests can also be utilized for qualifying materials for specific uses or serve as a basis for lot acceptance during purchase. In some cases...
