ESA ECSS-Q-ST-70-09C Electrical Connector Outgassing Testing
The ESA ECSS-Q-ST-70-09C standard is a critical guideline for outgassing testing of electrical connectors used in the aerospace and aviation sectors. This procedure ensures that materials do not off-gas volatile organic compounds (VOCs) or other contaminants that could contaminate spacecraft systems, thereby compromising mission success.
Outgassing refers to the release of gases from materials when exposed to a vacuum or reduced pressure environment—a condition commonly found in space. The standard is essential for aerospace and aviation components to ensure they meet stringent quality requirements set by international standards such as ISO 17852-4.
The testing process involves placing the electrical connector into a chamber where it is subjected to a vacuum environment at specified temperature cycles. The outgassed materials are captured, analyzed, and quantified to ensure compliance with the maximum allowable limits set by ECSS-Q-ST-70-09C. Failure to meet these criteria can lead to contamination of sensitive spacecraft systems, which could result in mission failure or significant delays.
Our laboratory uses state-of-the-art equipment to conduct this testing, ensuring accuracy and repeatability. The process is meticulously controlled with precise temperature cycling and vacuum conditions that mimic the space environment. This allows for a comprehensive assessment of the connector's outgassing properties under realistic conditions.
The standard also covers the preparation of samples prior to testing, which includes cleaning procedures and conditioning processes to ensure accurate measurement. The testing apparatus is designed to capture even trace amounts of volatile compounds, ensuring compliance with stringent environmental standards.
