DIN EN ISO 868 Shore Hardness Testing of Plastic Films
The DIN EN ISO 868 standard specifies the method for determining the hardness of plastic films using a Shore hardness tester. This test is essential in quality control, ensuring that products meet the required specifications and are fit for their intended use. The Shore hardness measurement provides valuable insights into the mechanical properties of plastic materials, which are critical parameters in product design and development.
During this testing process, small samples of plastic films or sheets are subjected to indentation by a standardized indenter under controlled conditions. The depth of penetration is measured with precision, allowing for accurate determination of the hardness value. This method is particularly useful for assessing the rigidity and flexibility of plastic materials, which can vary significantly depending on the formulation and processing techniques used.
The Shore hardness test is performed using a Shore A scale, which ranges from 0 to 100. For plastic films and sheets, values typically range between 25 and 85 Shore A units, with higher numbers indicating greater rigidity. This test is not only crucial for quality assurance but also plays a key role in research and development (R&D) processes where material properties need to be optimized.
A key aspect of this testing method involves the preparation of the samples. Samples are cut into standard sizes and shapes, ensuring that each sample is representative of the entire batch. The surface of these samples must be smooth and free from defects that could affect the test results. Proper specimen preparation ensures accurate and reliable measurements.
The instrumentation used for this test includes a Shore hardness tester capable of providing precise readings. These testers are equipped with standardized indenters that ensure consistent testing conditions across different samples. The equipment is calibrated regularly to maintain accuracy and reliability. Calibrating the instrument before each batch of tests helps prevent errors due to wear or misalignment.
The process begins by selecting a sample from the batch, ensuring it meets the required dimensions. The sample is then mounted on the testing machine in a manner that allows for accurate measurement of the indentation depth. Once positioned, the tester applies force gradually until the specified penetration depth is achieved. The machine records this data automatically and converts it into a Shore hardness value.
After conducting multiple tests on several samples from each batch, statistical analysis can be performed to determine if the results fall within acceptable limits defined by industry standards or customer specifications. If any sample fails to meet these criteria, further investigation is warranted to identify potential issues in manufacturing processes that may need correction.
The importance of DIN EN ISO 868 Shore hardness testing extends beyond just compliance with international regulations; it helps manufacturers ensure consistent product quality and reliability across all batches produced. By regularly performing this test during production cycles, companies can catch deviations early on before they become significant problems later in the supply chain or end-user applications.
This standard is widely accepted globally due to its robustness and repeatability, making it a preferred choice among industries dealing with plastic materials. Its widespread adoption ensures uniformity in testing practices worldwide, facilitating easier communication between suppliers and customers across different regions.
