JIS K 7361 Barrier Properties Testing of Outdoor Plastic Films
The JIS K 7361 standard is a critical component in ensuring that outdoor plastic films, used extensively across various sectors such as agriculture and construction, meet the required performance standards for moisture vapor transmission rate (MVTR), water vapor permeability, oxygen permeability, and carbon dioxide permeability. These properties are essential to prevent degradation due to environmental factors like humidity, UV radiation, and temperature fluctuations.
The testing of barrier properties is particularly important in outdoor plastics because they are often used as protective films for plants or structures exposed to the elements. By accurately measuring these properties, manufacturers can ensure that their products not only provide the necessary protection but also maintain their integrity over time.
Testing according to JIS K 7361 involves precise measurement of moisture vapor transmission rates under controlled conditions. This process helps identify any potential weaknesses in the film's barrier performance which could lead to premature degradation or loss of protective function. The test parameters include temperature, humidity levels, and exposure times that simulate real-world conditions where these films will be used.
Proper specimen preparation is crucial for obtaining accurate results from JIS K 7361 tests. Specimens must be cut to standard dimensions specified in the relevant sections of the JIS document. Ensuring consistent thickness and surface integrity can significantly impact the test outcomes, hence it's vital that they are prepared under controlled conditions.
The testing equipment used for this purpose includes permeameters designed specifically for measuring barrier properties. These instruments provide highly accurate measurements necessary to comply with international standards like JIS K 7361. Once the specimens have been prepared and placed into the instrument, the test can begin by subjecting them to specified temperature and humidity conditions.
After the prescribed exposure period has elapsed, the instrument calculates the rate at which water vapor or other gases pass through the material based on changes in weight or pressure inside the chamber. These measurements allow for comparison with industry benchmarks ensuring that products meet expected performance levels.
The results of JIS K 7361 tests are typically reported as MVTR values expressed in g/m²·day, which represent how much moisture vapor passes through a given area over time under specified conditions. Reporting these figures provides valuable insights into the effectiveness of different materials against environmental factors like humidity.
Compliance with JIS K 7361 ensures that manufacturers produce high-quality outdoor plastic films capable of delivering optimal protection while maintaining durability and longevity in harsh environments. This standard plays a key role in quality assurance processes by providing consistent criteria for evaluating barrier properties across various types of plastics used outdoors.
Non-compliance with JIS K 7361 can result in substandard products that fail to meet the required performance standards, leading to reduced effectiveness and potential damage to crops or structures. It is therefore crucial that all parties involved understand and adhere strictly to this important testing protocol when developing and manufacturing outdoor plastic films.

Applied Standards
The application of JIS K 7361 is primarily focused on evaluating the barrier properties of outdoor plastic films, which are crucial for their performance in various applications. This includes agricultural mulch films used to retain soil moisture and control weed growth, as well as construction materials like geomembranes that provide protection against water infiltration.
- For agriculture, ensuring proper barrier properties helps improve crop yields by maintaining optimal conditions within the root zone.
- In construction, effective barriers prevent leaks in waterproofing systems, extending the lifespan of buildings and infrastructure projects.
