ASTM E595-15 Testing System

Automated Outgassing Testing System Compliant with ASTM E595-15

Go further with our automated solution for determining Total Mass Loss (TML) and Collected Volatile Condensable Materials (CVCM), achieve reliable and repeatable results with full ASTM compliance.

Thermal vacuum testing is an essential for the qualification of materials and samples in a wide range of industries, not only related to areospace industry. To address this need, REDshift developed an innovative automated system fully compliant with ASTM E595-15, ensuring both functional reliability and structural integrity of materials under extreme conditions such as those in high vacuum environments.

How it works

Testing procedures quantify outgassing and evaluate thermal behaviour and material stability. The REDshift E595 TML system is equipped with a desktop application software, giving full control over every parameter.
Below is a brief overview of the method performed:

• Samples pre-conditioned are introduced in the boats.
• Vacuum starts at least at 7 × 10−3 Pa (5 × 10−5 torr), heating at 125 °C for 24 hours. This causes vapor from the heated specimen to stream from the hole in the specimen compartment.
• Vapor passes into a collector chamber in which it condenses on a previously-weighed and independently temperature-controlled,
chromium-plated collector plate at 25 °C.
• After 24-h, the chamber is cooled and the repressurized with dry, inert gas. The specimen and the collector plates are weighed and the percentages of TML and CVCM are obtained.
• If desired, the specimen is stored for 24-h at 23 °C and 50 % R.H. to permit sorption of water vapor. The specimen mass after this exposure is determined and the percentage WVR is obtained.

Core Test Capabilities

VACUUM STABILITY

Continuously controlled vacuum, temperature and humidity during the 24-h test with implementation of alerts and audit logs.

ENVIRONMENTAL CONDITIONING

Assesses a material’s potential to contaminate nearby components via its outgassing properties. Leave the long and repetitive work to the E595 system.

PERFORMANCE EVALUATION

Tests mechanical stability and functional integrity of materials after exposure to a simulated extreme stress condition by monitoring the released vapors.
