Coal and Charcoal Testing

Charcoal is still a popular fuel used by barbecue enthusiasts. The charcoal briquet is the most common form of charcoal used by consumers today. Quality of the charcoal is an important attribute to assure performance and safety. To ensure high quality, charcoal testing briquets for moisture and sulfur content as well as how much smoke is generated just to name just a couple of tests. Ash testing determines the residue remaining after burning the charcoal. Since charcoal is produced in many places around the world, the content and composition of charcoal can vary widely. A standardized range of tests can also measure the performance of the briquet such as how long it burns and how much heat (BTUs) it will generate. Much in the same way anthracite and bituminous coal can be tested according to similar methods. Dallas Laboratories has been a leading lab for many years in the testing of charcoal and coal for performance and emission and residue.
