Chemical Resistance Testing
Chemical resistance testing refers to a material’s
resistance to the application of chemicals to its
surface. Painted parts as well as fabrics are the most
common materials tested. For painted parts, the
samples are evaluated for cracking, puckering,
swelling, and loss of adhesion. For fabrics, the
samples are evaluated for their ability to be cleaned
after being soiled. The chemicals can be applied by
several different methods, a few examples are: sample
immersion, dripping, and wiping. The chemicals used
range from orange juice and motor oil to synthetic
soil and artificial perspiration. This testing can
also be conducted at specified temperatures. |
