Specific to Mixed Acid Etchants.

Analytical procedures and specifications are introduced for each type. Etchants within all of the requirements can be described as "meeting SEMI specifications." Where analytical procedure differs from that provided and is substituted by a user or supplier, the burden of proof is on said user or supplier to confirm the equivalency.
