Corrosion and Corrosivity

As of October 1, 2005, the DOT no longer references ASTM G 31, but instead adopts the UN Model Regulations Section 37 test protocol for evaluating substances for possible assignment to Class 8 Packing Group III materials. The new protocol is more elaborate and complex and requires a longer exposure time, greater number of test specimens, more sophisticated interpretation of the resultant data, etc.

A manufacturer asked Alliance Technologies to test a liquid product used in printer ink products to determine the DOT packaging group for proper shipping.

In a separate project, Alliance focused on the corrosion testing of 1020 carbon steel for four weeks according to specific protocols determining that the corrosion rates of carbon steel and aluminum in this product did not exceed the DOT threshold rates.
