ISO 1402 Pressure Tests

ISO 1402 outlines the methods you'll use to conduct pressure tests on composite hoses, ensuring they meet required safety standards. When preparing to apply this standard, you must first understand the significance of pressure duration and test repeatability, two critical parameters that affect the reliability and safety of the hoses in various applications.

Pressure duration refers to the length of time the hose must withstand the test pressure without failure. This duration is important as it simulates the real-world conditions under which the hose will operate, ensuring it can sustain long-term pressure demands. The standard specifies minimum durations for different types of tests, such as short-term burst or long-term stability, to guarantee performance across a range of expected conditions.

Test repeatability is another essential aspect covered by ISO 1402. It ensures that when you repeat the same test under identical conditions, the results will be consistent. This consistency is essential for validating the quality and reliability of the hose. To achieve high repeatability, you must strictly adhere to the standardized procedures, including the preparation of the hose, the environment of the testing area, and the exact method of applying pressure.

ASTM D380 Testing Procedures

While ISO 1402 provides a solid foundation for pressure testing, ASTM D380 outlines specific procedures to evaluate the performance and durability of composite hoses under varied conditions.
