Deposit Weight (DWD) Analyses

The Sheppard T. Powell Associates, LLC (STPA) laboratory has the expertise to handle and analyze metallurgical samples for deposit weight which is also sometimes called deposit weight density (DWD) using the following analytical procedures.

• Mechanical Method of Deposit Weight (ASTM D3483, Method A)
• Bead Blast Method of Deposit Weight (ASTM D3483, Method C / NACE TM-0199-99)

The STPA normal procedure for determining the DWD of a metallurgical sample is the mechanical method. The DWD or specific deposit weight is reported in grams/square foot (g/ft²).
