Deposit Weight (DWD) Analyses

STPA laboratory has the expertise to handle and analyze metallurgical samples for deposit weight and 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)

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).
