Mechanical environment reliability

Test Background

Quick connectors need to withstand environmental stresses such as vibration, temperature changes, and humidity during transportation, installation, and operation. Insufficient mechanical environmental reliability may lead to connector loosening, seal failure, or material aging.

Test Introduction

Through vibration tests, temperature cycle tests, damp-heat aging tests, and extreme temperature storage tests, the environmental stresses that quick connectors are subjected to during their entire life cycle are simulated to verify their environmental adaptability.

Testing Objectives

Verify that there is no leakage or loosening under vibration conditions

Evaluate the impact of temperature cycles on sealing materials

Ensure that there is no corrosion or aging in a damp-heat environment

Verify the functional integrity after extreme temperature storage

FAQ
Q: Will the insertion and extraction forces change after wet-heat aging? A: The sealing material may swell or harden, resulting in changes in the insertion and extraction force, which need to be controlled within ±20%.
