ASTM E139: Standard for material creep testing
What is ASTM E139?
ASTM E139 is a standardized test method developed for measuring the mechanical and thermal properties of materials under long-term stress. This standard is essential for evaluating the creep behavior of materials, such as metals and plastics, that are loaded under constant stress or high temperatures. The test is very important in various industries, such as aviation, energy and construction, where ensuring the structural integrity of materials is crucial.
Why is ASTM E139 important?
The application of ASTM E139 offers several advantages:
- Long-term performance: By measuring creep behavior, manufacturers can evaluate the performance of their materials in critical applications.
- Quality Assurance: The standard helps companies comply with the required quality standards and regulations, which is essential for market acceptance.
- Improved designs: Test results enable engineers to optimize their designs and select materials that are suitable for long-term stress.
How does ASTM E139 work?
The process typically includes the following steps:
- Sample preparation: materials are prepared according to established standards for accurate measurements.
- Application of loads: the sample is exposed to controlled forces that are applied over a long period of time.
- Data collection: During the test, deformations and other important parameters are measured and analyzed.
Relation to ISO 204
ISO 204 is a relevant standard that provides procedures for testing the mechanical properties of plastics, specifically focused on their response to long-term stress. While ASTM E139 focuses on a wider range of materials, ISO 204 provides specific guidelines for thermoplastic and thermoset plastics. The use of both standards enables companies to gain a detailed insight into the long-term performance of their products under different conditions.
