What is EN ISO 13390:2019?

EN ISO 13390:2019 is an international standard that provides guidelines and requirements for the determination of material properties through the use of dynamic mechanical analysis (DMA). DMA is a technique used to measure the mechanical behavior of materials as a function of time, temperature, and frequency. This standard applies to various types of materials, including plastics, rubber, composites, and metals.

Understanding Dynamic Mechanical Analysis (DMA)

DMA is a versatile method that can be used for characterizing a wide range of material properties such as modulus, damping, and viscoelastic behavior. It involves subjecting a sample to periodic stress or strain and measuring the resulting response. By applying different frequencies, temperatures, and amplitudes, researchers can gain insight into how the material behaves under different conditions.

The key advantage of DMA is its ability to provide detailed information about a material's behavior over a broad range of temperatures and frequencies. This allows engineers and scientists to better predict how a material will perform in real-world applications and tailor its properties to specific requirements.

Key Features of EN ISO 13390:2019

EN ISO 13390:2019 specifies the necessary procedures and calculations for carrying out DMA tests and reporting the results. It covers sample preparation, test conditions, data analysis, and interpretation. The standard also provides guidance on test equipment calibration, verification, and validation.

One important aspect of this standard is the determination of key parameters for characterizing a material's viscoelastic properties, such as storage modulus, loss modulus, and damping factor. These parameters are crucial in understanding how a material responds to stress and strain, and they play a vital role in engineering design and material selection.

EN ISO 13390:2019 is a valuable tool for researchers, engineers, and manufacturers who rely on accurate material property data to optimize product performance. By following the guidelines outlined in this standard, they can ensure consistent and reliable test results, leading to improved product quality and reliability.
