Transition from Qualitative to Quantitative: Instrumentation of Tests
Precision in measuring various material properties and environmental conditions is a crucial concern in many application domains. Instrumentation technologies enable a shift from qualitative to quantitative evaluation by providing measurable and reliable data. This transformation is achieved through physical and environmental data acquisition systems capable of measuring factors such as shocks, vibrations, temperature, humidity, and pressure.
Physical and Environmental Data Acquisition Systems
One of the most commonly used tools in this context is the accelerometer, which allows measuring the shocks experienced by products during tests. With this precise measurement, it becomes possible to simulate real-life situations a product may encounter and evaluate its resistance and durability based on this data.
Other systems monitor and measure environmental factors such as temperature, humidity, and pressure. This data can be particularly useful for tests under specific conditions or to assess the impact of these factors on the product's performance.
Characterization of Packaging Materials
Another crucial aspect of instrumentation involves the characterization of packaging materials. Whether for comparative or ecological reasons, it is possible to plot dynamic damping curves, also known as "cushion curves." These curves visualize the efficiency of a packaging material in damping shocks and vibrations. This can be particularly helpful for evaluating and comparing the effectiveness of different materials or for verifying compliance with specific environmental standards.
Product Resonance Research
Instrumentation also enables product resonance research by performing frequency spectrum scans. These analyses can reveal potential structural weaknesses or areas of stress in a product, which can be valuable for improving product design and long-term durability.
Behavioral Analysis with High-Speed Camera
Finally, the use of a high-speed camera can provide valuable insights into product behavior during tests. By recording tests in real-time, it is possible to analyze product behavior under different stresses and conditions, which can help identify potential issues and make targeted improvements.
Standards
Instrumentation can also help ensure compliance with specific standards. For instance, ASTM D6537, D1596, EN15433, and other standards can be met through the use of specific instruments and precise testing protocols.
