EN 14112 Oxidation Stability Biodiesel Rancimat Testing
The EN 14112 standard is a European Standard that specifies the procedure for determining the oxidation stability of biodiesel fuels. This test, commonly referred to as the Rancimat test, involves subjecting samples to controlled heating in an atmosphere of nitrogen or oxygen with a constant stirring rate under specified conditions. The primary goal of this testing method is to assess how well a fuel sample resists oxidative degradation over time.
The EN 14112 procedure is designed to simulate the real-world use environment, where biodiesel may be exposed to elevated temperatures and oxidative stress. By measuring the rate at which peroxides form in the fuel during this process, we can predict its shelf life and performance under various conditions. This information is crucial for quality managers, compliance officers, R&D engineers, and procurement teams responsible for ensuring that fuels meet strict regulatory requirements.
The test procedure begins with careful sample preparation to ensure accuracy. The biodiesel sample must be representative of the batch it represents and free from contaminants or additives that could skew results. Once prepared, the sample is introduced into the Rancimat apparatus, which consists of a glass tube immersed in an oil bath at a controlled temperature.
The test involves monitoring the formation of peroxides by measuring the absorbance of light at 235 nm using a photometer integrated into the Rancimat. The rate of increase in absorbance over time provides a direct measure of the fuel's oxidative stability. This process continues until an endpoint is reached, typically when no further significant increases are observed.
The results from this test provide valuable insights into the quality and shelf life of biodiesel fuels. Compliance officers can use these data points to ensure that their products meet regulatory standards such as EN 14214 or ASTM D6751. R&D engineers benefit by gaining a deeper understanding of how different components affect fuel stability, allowing them to optimize formulations for improved performance.
For procurement teams, knowing the oxidation stability of biodiesel helps in selecting suppliers who consistently deliver high-quality products. Understanding these parameters also aids quality managers in setting appropriate targets and monitoring progress towards improving product quality.
