Designed for Performance Verification
IEC 60068-3-5 focuses on verifying the performance of unloaded temperature test chambers, ensuring they meet the stringent requirements set forth in the IEC 60068-2 series—such as thermal shock (IEC 60068-2-14), damp heat cycling (IEC 60068-2-30), and other climate-related test procedures. At TESTEQ, our chambers are not only compliant but optimized for precision monitoring, supporting users in routine validation of controlled environments essential for aerospace, automotive, electronics, and industrial R&D sectors.
This standard is essential for:
Validating chamber accuracy before conducting mission-critical reliability tests
Ensuring consistent results across multiple test cycles and locations
Supporting quality audits, ISO certifications, and regulatory compliance
At its core, IEC 60068-3-5 verifies three key aspects: temperature ramp rates, thermal stability, and spatial uniformity—all of which TESTEQ has mastered through proprietary engineering.
Extreme Thermal Performance: +125°C → –55°C at ≥10°C/min (Unloaded, Full-Stroke Average)
TESTEQ’s high-speed thermal chambers achieve an exceptional average cooling rate of ≥10°C per minute from +125°C down to –55°C (unloaded)—well beyond typical industry benchmarks. This enables:
Accelerated life testing (ALT) with realistic thermal shock simulation
Faster turnaround times without sacrificing data integrity
Compliance with military, automotive, and telecom standards requiring aggressive thermal profiles
This level of performance is made possible by:
Dual-stage cascade refrigeration systems
High-efficiency insulation and airflow design
Intelligent PID+ control algorithms that optimize energy use while maintaining precise trajectory tracking
Whether simulating desert-to-alpine transitions or satellite re-entry thermal swings, TESTEQ ensures your products face the extremes—repeatedly, reliably.
Built for Real-World Durability & Repeatability
Compliance isn’t just about passing a single test—it's about enduring thousands. TESTEQ chambers are built for long-term reliability, designed to handle repeated thermal cycling, including demanding sequences like 23°C/50%RH ↔ 95°C/50%RH per IEC 60068-2-30. Combined with support for auxiliary standards like IEC 60068-3-11 (thermal transition rate verification), our systems offer full traceability and validation capabilities essential for ISO-accredited labs and export-ready certification.
In today’s competitive markets, environmental testing must be more than compliant—it must be predictable, scalable, and future-proof. With IEC 60068-3-5-compliant design, industry-leading ramp rates, and lab-grade precision, TESTEQ delivers turnkey solutions trusted by engineers worldwide. Whether validating component durability or qualifying next-gen electronics, our chambers provide the foundation for confidence in every test cycle.
