Quality & Certifications

Interm modules are built to a documented quality system with third-party verification. Every module is tested before shipment.

Certifications & Standards

ISO

ISO 9001 Certificate

ISO 9001:2015 certified quality management system covering design, manufacture, and delivery of thermoelectric modules.

MIL-STD

MIL-STD-883 Test Summary

Selected Interm TEC modules pass MIL-STD-883 environmental and mechanical testing, including thermal shock, vibration, and hermeticity screening.

MTBF

MTBF Statement

Documented mean time between failures of ≥200,000 hours under standard operating conditions, calculated per Telcordia SR-332 methodology with field return data from production shipments.

ROHS

RoHS Compliance Declaration

Standard catalog modules comply with EU RoHS Directive 2011/65/EU. High-temperature variants (Tmax=150°C) are exempt per Annex III due to the physical requirements of lead-containing solders at elevated temperatures.

ISO 9001:2015 Certificate — Interm

Manufacturing & Testing Processes

100% Final Test

Every Interm module passes a full electrical test before shipment. Performance parameters (dTmax, Qmax, Imax, Vmax) are measured at ambient and verified against specification limits.

Harman Method

We use the Harman AC/DC measurement technique to verify the thermoelectric figure of merit (ZT) on production modules, confirming material quality and junction integrity at the device level.

Vertical Integration

Interm is one of fewer than 5 manufacturers globally that grow their own Bi₂Te₃ semiconductor material. Full control from crystal growth to finished module eliminates supply chain variance.
