ASTM E793 Enthalpy of Fusion by DSC
The ASTM E793 standard method is a critical tool used to measure the enthalpy of fusion of crystalline materials. This test is particularly useful for characterizing polymers, metals, and alloys that exhibit a clear melting transition when heated. The primary focus of this service is on determining how much energy (in joules per gram) is required to melt one gram of a substance at its melting point.
The Differential Scanning Calorimetry (DSC) technique is employed in ASTM E793. During the test, a sample and an empty reference crucible are heated at a constant rate while their temperatures are measured continuously. The difference between the heat flows to the sample and the reference is monitored as a function of temperature.
The enthalpy of fusion can be calculated from the area under the heat flow curve during the melting process. This test provides detailed insights into the crystalline structure, purity, and molecular weight distribution of materials. It’s widely used in quality control to ensure uniformity across batches and in research and development for material characterization.
For accurate results, proper sample preparation is crucial. The sample should be homogeneous with no visible impurities that could affect the melting process. Commonly tested materials include polyethylene, polystyrene, and certain metals like copper or aluminum.
The DSC instrument used in this service must adhere to international standards such as ASTM E793. This ensures consistency and reliability across tests performed by different laboratories around the world. The equipment is calibrated regularly using certified reference materials provided by organizations like NIST (National Institute of Standards and Technology).
ASTM E793 also specifies that samples should be heated at a controlled rate, typically 10°C per minute, to ensure consistent results. The melting point of the sample is determined from the peak temperature during the test.
The data generated by this service can help in various applications including pharmaceuticals where it aids in understanding the polymorphic changes of active ingredients; electronics manufacturing where it assists in selecting appropriate solder materials; and aerospace engineering where it contributes to optimizing fuel tank designs.
In summary, ASTM E793 Enthalpy of Fusion testing is a vital method for material scientists and quality assurance professionals. It provides detailed information about the thermodynamic properties of crystalline materials which can be leveraged across numerous industries from pharmaceuticals to aerospace.
