📋 Material Calibration & Data Submission Protocol

To maintain the metrological integrity of our Substance Database, all proposed material additions or density adjustments must satisfy our metrological verification criteria:

  • Authoritative Citation: Submissions must reference a recognized international standard body (such as NIST, ASTM International, ISO, API, USDA FoodData Central, or published IUPAC/CRC handbooks).
  • Temperature Specification: Density without reference temperature is mathematically incomplete. Please specify whether density is calibrated at standard petroleum reference (15°C / 60°F) or standard room ambient (20°C / 68°F).
  • Measurement Methodology: Disclose whether values represent true physical density, apparent specific gravity in air, or settled granular bulk density (for agricultural solids).
