The Subcommittee covers the following topics:

• Realisation and dissemination of the SI unit of pressure specifically 
  • in the areas of gauge, differential and absolute pressure as well as very low gas flow related to vacuum and sealing technology; 
  • in gaseous and liquid media; 
  • as static and dynamic quantity. 
• Improvement, development and application of pressure measurement and related technologies such as 
  • dead weight and force compensated pressure balances; 
  • liquid column manometry; 
  • static and dynamic expansion systems; 
  • pressure sensors; 
  • dimensional metrology; 
  • material study; 
  • laser interferometry and liquid density measurement; 
  • flow modelling; 
  • optical absorption spectroscopy and refractometry. 
• Development of methods and guides for pressure calibration 
• Comparison of pressure standards
