PLANTSERV^® Charpy Impact and Tensile Testing in Liquid Helium (4.2 K / -269° C)

Reliable and Precision-engineered Testing Solutions for Extremely Low Temperatures

Cryogenic processes and applications demand advanced material testing solutions to evaluate the durability of structural alloys under extreme conditions. PLANTSERV^® ’s cutting-edge test setups for tensile and impact testing at liquid helium temperatures (4.2 K / -269° C) offer unmatched reliability, accuracy and efficiency. They adhere to global testing standards such as ASTM E1450, ISO 19819 and ISO 148.

Charpy Impact Testing — Cryogenic Precision You Can Trust

Our impact testing equipment is designed to fulfill the requirements defined in ISO 148, using liquid helium for cooling:

Encapsulation of Specimens  
For maximum temperature retention, the notched impact specimen is encapsulated to prevent the temperature from rising during transport from the dewar to the impact testing machine. Encapsulation of the specimen is a key prerequisite for ensuring ISO 148 compliance at liquid helium temperatures.

Enhanced Dewar Design
Our specialized system utilizes liquid nitrogen pre-cooling followed by liquid helium, protecting the testing environment against helium’s high volatility due to its extremely low evaporation enthalpy.

 

Advanced Setup for Tensile Testing – Reliable Data for High‑Performance Alloys

Highlights of our offering for structural alloys in ultra-low temperature environments include:

Specialized Dewar Technology
Engineered to cool metals to liquid helium levels within a specific timeframe, our vacuum-insulated dewars provide precise temperature control during testing. By minimizing heat transfer, the dewar achieves optimal conditions for even the most demanding requirements.

Compliance with Global Standards
Our tensile tests are conducted in full alignment with:

• ASTM E1450: Tension Testing of Structural Alloys in Liquid Helium
• ISO 19819: Metallic Materials — Tensile Testing in Liquid Helium
• ISO 6892-3: Metallic materials — Tensile testing — Part 3: Method of test at low temperature (liquid nitrogen temperatures of 77 K or -196° C)

High-performance Material Testing for Demanding Industries
This solution is ideal for industries requiring high-performance alloys such as aerospace and energy, and for cryogenic environments, where reliability and durability are non-negotiable.

Cryogenic Excellence Laboratory for Advanced Material Insights in Challenging LHe Environments

Our laboratory is highly specialized in material performance testing, delivering reliable data under a broad spectrum of conditions. Complementing our particular focus on cryogenic temperatures as low as 4.2 K / -269° C (liquid helium / LHe), we also provide testing at other cryogenic benchmarks such as 77 K / -196° C (liquid nitrogen / LIN).
