Instron Bluehill Universal adds multi-furnace high-temperature testing

Instron has released a High-Temperature Add-On for its Bluehill Universal materials testing software that extends integrated ASTM E21 and ISO 6892-2 full-test temperature compliance to multi-furnace workflows. The company positions the release around a practical constraint: in elevated-temperature tensile testing, furnace heating and soak times often exceed the duration of the mechanical test itself, making throughput the bottleneck.

What does the add-on change?

The software now allows multiple add-on furnaces to mount to a single test frame. Additional specimens heat and soak while a prepared specimen undergoes testing, and all associated furnace and mechanical data land in the same specimen record. Instron lists three resulting benefits: increased testing throughput, reduced idle time between tests, and streamlined data management across multiple specimens.

The add-on consolidates control and data capture into one system, which Instron says reduces manual intervention, improves testing consistency, and raises overall productivity.

How does it handle temperature control?

Elevated-temperature tensile testing demands precise control and continuous monitoring of indicated temperature from heat-up and soak through the determination of mechanical properties. The stakes are material-driven: elevated-temperature alloys are acutely sensitive to the temperature and strain rate at which their properties are determined. That sensitivity is why ASTM E21 and ISO 6892-2 specify temperature control and soak behavior — and why the software tracks compliance continuously rather than at isolated points.

Instron's proprietary Automatic Loop Control algorithm addresses the strain-rate half of that equation. It adjusts system response automatically to the changing stiffness of the specimen during the test, which the company describes as best-in-class strain rate control. Bluehill Universal builds on this foundation, and the latest release adds secure data-integrity protocols to critical temperature parameters and results.

What can operators configure?

New furnace-specific controls in Bluehill Universal let users:

• Set target temperatures and soak durations directly in the software
• Define and monitor acceptable overshoot limits
• Track multiple thermocouples for secondary soaking configurations, or apply optional furnace-level monitoring

The workflow support runs from thermocouple installation through reaching setpoint and confirming temperature stability, with continuous monitoring and documentation at each step. Temperature and materials data combine into a single test record with full traceability, and the record exports seamlessly for downstream analysis. Continuous temperature recording during heating, soak, and testing phases supports compliance and yields a complete record of test conditions.

What does the vendor claim versus measure?

Instron claims the highest accuracy and repeatability in mechanical testing and describes the add-on as delivering the most accurate, repeatable, and reproducible results. The company did not publish quantitative accuracy figures, calibration intervals, or test conditions with the announcement, so labs evaluating the release should verify performance against their own ASTM E21 and ISO 6892-2 qualification protocols. The compliance-relevant capabilities — continuous indicated-temperature recording, soak monitoring, and overshoot limits — are concrete software functions rather than performance claims.

Dean Lovewell, Metals Market Manager at Instron, framed the release around data management: "With this add-on, we're building on a strong foundation of elevated-temperature testing capabilities, including automatic loop control, to deliver even greater confidence in test results. By enhancing how temperature and materials data are managed within a single environment, we're helping customers exceed compliance requirements while strengthening data integrity, security, and traceability — so they can trust every result and every record."

For metals labs running elevated-temperature tensile programs, the open question is adoption economics: whether mounting multiple furnaces on one frame and consolidating records in one software environment cuts enough soak-related idle time to justify the add-on against existing manual or hybrid workflows.
