Lists other ASTM standards that are essential for using D6307, including:

  • ASTM D979 (Sampling of Asphalt Mixtures)
  • ASTM D3666 (Specification for testing agencies)
  • ASTM D4753 (Specification for laboratory balances)

Procedure Summary for Daily Use

  1. Dry the sample to constant mass at 110 ± 5°C.
  2. Record initial mass (including the pan).
  3. Preheat the furnace to the specified ignition temperature (typically 538°C).
  4. Place the sample in the furnace and ignite until carbon is gone (usually 30–45 minutes).
  5. Cool the residue to room temperature in a desiccator.
  6. Weigh the residue (including the pan).
  7. Calculate binder content using the formula with your correction factor.

Why is ASTM D6307 Important?

  • Speed: A test that once took hours using solvent extraction can now be completed in 30–45 minutes.
  • Safety: Eliminates the use of hazardous solvents (chlorinated solvents are now heavily regulated).
  • Accuracy: When calibrated correctly, the ignition method offers excellent accuracy for most aggregate types.
  • Quality Control: Allows producers to quickly adjust plant operations to keep binder content within specification, saving millions in rejected materials.

Key Definitions

  • Antimicrobial Agent: A chemical or physical agent that destroys, inactivates, or inhibits the growth of microorganisms.
  • Hydrophobic Materials: Materials that repel or resist water.
  • Polymeric Materials: Materials composed of large, repeating molecular structures (polymers).

Introduction to ASTM D6307

Propylene, also known as propene, is a critical raw material in the production of polypropylene, a widely used plastic in various applications ranging from packaging materials to automotive parts. The purity of propylene concentrates is paramount, as impurities can significantly affect the quality of the final product and the efficiency of the production process. ASTM D6307 is designed to provide a precise method for determining hydrocarbon traces in propylene concentrates, thereby ensuring that the material meets the required specifications for industrial use.
