 Committee Scope

The Subcommittee on Measurement Quality (COMQ) is a joint committee with ASTM International (ASTM) through ASTM Committee D02. However, not all standards developed by the committee are joint API-ASTM standards.

COMQ develops, approves, and maintains standards pertaining to measurement quality of hydrocarbons (sometimes in conjunction with other COPM Subcommittees) including:

  • Temperature Determination, MPMS Chapter 7
  • Sampling, MPMS Chapter 8
  • Density Determination, MPMS Chapter 9
  • Sediment & Water Determination, MPMS Chapter 10
  • Physical Properties, MPMS Chapter 11
  • Statistics, MPMS Chapter 13
