A Mill Test Report (MTR) documents a material''s physical and chemical properties. These quality assurance certificates show a metal product''s compliance with international standards. ANSI and ASME are two of the most important and common standards that require MTR information. Other names for mill test reports include: Certified Mill Test Report.

Powder processing operations can generate vast quantities of electrostatic charge via the movement of powder. The standard method of charging on powder processing operations is due to tribo-electrification, which is basically the contact and separation of the powder with processing equipment, the powder itself, or other factors that can cause charging, like surface contaminants.
