Product Description Test Method: Provides an indication of relative coke forming properties of petroleum oils. The residue remaining after a specified period of evaporation and pyrolysis is calculated as a percentage of the original sample.
Features and Benefits
- Conforms to ASTM D189 specifications

A weighed quantity of sample is placed in a crucible and heated to a high temperature for a fixed period. The crucible and the carbonaceous residue is cooled in a desiccator and weighed. The residue remaining is calculated as a percentage of the original sample and reported as conradson carbon residue.

Conforms to the specifications of: ASTM D189, D6074; ANS Z-11.25; IP 13; ISO 6615; DIN 51551; FTM 791-5001; NF T 60-116.

The burner that comes with this is not recommended for propane so be sure to order K80039-LPG High Temperature Burner LPG as well where propane will be used.
