Why is the copper corrosion strip test by industrial aromatic hydrocarbons important?

This ASTM D849 is suitable for setting specifications, for use as an internal quality control tool, and for use in development or research work on industrial aromatic hydrocarbons and related materials. It also gives an indication of the presence of certain corrosive substances which may corrode equipment, such as acidic compounds or sulfur compounds.

Summary of the test method

A polished copper strip is immersed in 200 mL of specimen in a flask with a condenser and placed in boiling water for 30 minutes. At the end of this period, the copper strip is removed and compared with the ASTM copper strip corrosion standards.

Why should you use a  Tamson copper corrosion bath to determine corrosiveness to copper of industrial aromatic hydrocarbons?

Our copper corrosion baths are the most robust in the market with a temperature range from ambient +5°C to 250°C. The apparatus for ASTM D849 consists of a six position TC40 circulator bath and it is standard delivered with six sets of glassware (250 mL flask and condenser). The cover of the bath has six openings, each with a lid and stand-rods with clamps to hold the glassware in the same position. All essential parts of the copper corrosion bath are made from stainless steel. The copper corrosion bath has a standard drain to empty the bath content. All the required accessories and consumables for ASTM D849 tests are supplied by Tamson. Examples of consumables and accessories for copper corrosion tests are the ASTM copper strip corrosion test standard, copper strips (99.9% purity), P220 sanding paper, a multistrip vise, silicon carbide powder (1 kg), and flat viewing test tubes.
