The purpose of ASTM D1506 is to determine the ash content of carbon black. The quantity of non-carbon components left over after combustion is known as the ash content of carbon black. The catalyst in the feedstock and the water used in the production process are the primary ash sources. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM D1506 tests for our clients.
What Is the ASTM D1506 Test Method and How Does It Work?
| Muffle Furnace Technique | Porous quartz fiber crucibles with optional disks are ignited in a furnace set to 550–625°C for 15 minutes. Porcelain crucibles with covers are placed in a muffle furnace for an hour. After one hour of drying in a gravity-convection oven, the sample is weighed and cooked for sixteen or one and a half hours at 550°C. After that, the crucible is covered and weighed again until the mass remains consistent. |
| Microwave Furnace Technique | Crucibles and covers are preheated to 550°C for one hour, then cooled to room temperature to prepare carbon black. A carbon black sample is placed in a container and dried at 125°C in a gravity convection oven. Once the crucible is empty, it is weighed, and 2 grams of carbon black is added. The samples are placed in a desiccator, heated in an ashing chamber of a microwave furnace, and then the crucibles are taken out. Once the mass shift is less than 0.5 mg, the mass loss is calculated and heated. |
What Are the Test Specimen Requirements for ASTM D1506?
| Specimen Detail | Carbon black is the test specimen used in ASTM D1506 |
| Specimen Size | 2 ± 0.1 g of carbon black is used in the muffle furnace method. 2g of carbon black is used in the microwave furnace technique |
