EN ISO 15105 Gas Permeability Testing of Plastic Films
The EN ISO 15105 standard provides a comprehensive framework for determining the gas permeability properties of plastic films and sheets. This critical test is particularly important in sectors such as packaging, where understanding how gases interact with materials ensures product integrity and safety. In this context, gas permeability testing plays a pivotal role in optimizing barrier performance to extend shelf life and protect contents from spoilage.
The standard specifies the methodology for determining the rate at which different gases can pass through plastic films under controlled conditions of temperature, humidity, and pressure. This information is essential for quality managers and compliance officers who must ensure that their products meet regulatory standards and industry expectations. R&D engineers also rely on this data to innovate and improve product designs.
The testing process involves precise specimen preparation, which includes cutting the plastic film into standard-sized samples. These samples are then placed in a test cell with known gas concentrations and exposed to specific temperature and humidity levels. The rate at which gases permeate through the sample is measured using sensitive instrumentation, such as the diffusion constant method or mass balance approach.
The accuracy of these measurements directly impacts the reliability of the results, making it crucial for laboratories to adhere strictly to the standard’s procedures. Compliance officers need reliable data to ensure that their products meet regulatory requirements and industry benchmarks. For R&D engineers, this test is a cornerstone in developing new materials with enhanced barrier properties.
The EN ISO 15105 method allows for the testing of various gases, including oxygen (O₂), carbon dioxide (CO₂), nitrogen (N₂), and water vapor (H₂O). This versatility makes it applicable to a wide range of applications beyond just packaging. For instance, in medical device manufacturing, understanding gas permeability is crucial for ensuring that devices remain sterile over extended storage periods.
Another important aspect of this test is its contribution to the sustainability goals of many industries. By optimizing barrier properties, manufacturers can reduce material usage and improve recyclability without compromising product protection. This aligns with broader environmental objectives, making gas permeability testing an integral part of sustainable manufacturing practices.
The results from EN ISO 15105 tests are typically reported as the permeability coefficient (PC) or diffusion coefficient (D), which quantify how readily gases can pass through the film under specified conditions. These coefficients provide valuable insights into the material’s suitability for specific applications, enabling informed decisions in product development and quality assurance.
In conclusion, EN ISO 15105 gas permeability testing is a vital tool for industries that rely on plastic films to protect their products. By adhering to this standard, laboratories ensure accurate, reliable data that supports compliance, innovation, and sustainability goals across various sectors.
Applied Standards
The EN ISO 15105 standard is widely recognized for its rigorous methodology in determining gas permeability. It builds upon several international standards, including ASTM D3985 and ISO 15106, which are also used in similar testing protocols. These standards provide a consistent framework that ensures comparability of results across different laboratories and jurisdictions.
- EN ISO 15105: This standard specifies the procedure for determining the gas permeability of plastic films and sheets under controlled conditions.
- ASTM D3985: Although primarily focused on packaging materials, this American Society for Testing and Materials (ASTM) standard complements EN ISO 15105 by offering additional insights into the properties of gas barriers in various applications.
- ISO 15106: This international standard provides supplementary information on testing methods that can be used alongside EN ISO 15105 to ensure comprehensive evaluation of plastic films and sheets.
The use of these standards ensures a harmonized approach to quality assurance, facilitating seamless integration within global supply chains. Compliance with these standards is crucial for maintaining high-quality products and meeting international regulatory requirements.
