In today's demanding industries-from electronics to aerospace-materials and components are often required to perform under extreme heat conditions. High temperature testing plays a vital role in determining how these materials behave, degrade, or fail when exposed to elevated temperatures for extended periods. By simulating harsh thermal environments in a controlled setting, manufacturers gain the data needed to improve product durability, ensure compliance, and accelerate innovation.

LIB, a leading manufacturer of environmental test equipment, offers three major types of high temperature test chambers: standard temperature chambers, temperature cycling chambers, and thermal shock test chambers. Whether you're developing next-gen electronics or qualifying automotive polymers, LIB provides reliable and customizable solutions to meet various high temperature testing demands.
What Is High Temperature Testing?
High temperature testing refers to the exposure of samples to elevated heat levels, typically above 100°C, to observe their thermal resistance, aging behavior, and performance over time. It's used to simulate real-world operating conditions such as:
Prolonged exposure to heat during transportation or operation
Rapid thermal changes during power cycles
Material breakdown due to oxidation or thermal stress
By analyzing a material's ability to maintain integrity under high temperature, engineers can predict service life, verify safety margins, and comply with international durability standards.
LIB High Temperature Chambers: Overview
LIB offers three main types of test chambers tailored for different high heat simulation requirements.
1. Temperature Test Chamber
A versatile solution for constant high temperature or temperature-humidity testing, ideal for electronics, automotive components, and material stability studies.
Temperature range: -70°C ~ +150°C (optional up to +180°C)
Humidity range: 20% ~ 98% RH
Uniform air circulation and precision PID control
Fully programmable touchscreen controller with Ethernet/USB connectivity
Applications: Thermal aging, accelerated life tests, and performance evaluations under stable or combined thermal-humidity conditions.

2. Temperature Cycling Chamber
Designed for rapid heating and cooling cycles to simulate repeated thermal stress. Suitable for electronics, PCBs, automotive modules, and defense hardware.
Rapid temperature changes: Up to 5°C/min (customizable up to 15°C/min)
Operating range: -70°C ~ +180°C
Ideal for fatigue testing, thermal ramp/soak profiles
Customizable volumes and shelves for multi-sample testing
Applications: Detecting failures caused by thermal fatigue, solder cracking, and stress delamination.

3. Thermal Shock Test Chamber
Simulates extreme temperature shifts in seconds. Best for identifying product resilience against abrupt thermal stress.
Dual or triple zone chamber design (hot, ambient, cold)
Temperature range: +150°C to -70°C
Basket or drawer-style transfer for rapid movement
Programmable shock cycles, with automatic operation and logging
Applications: Semiconductor reliability, aerospace component qualification, and plastic/metal bonding integrity testing.

Typical Applications Across Industries
LIB's high-temperature test chambers are utilized in diverse sectors:
Automotive: Testing thermal aging of plastics, rubber gaskets, and interior components.
Electronics: Stress testing PCBs, solder joints, and battery enclosures under heat load.
Energy: Simulating long-term operation of solar modules or battery packs.
Aerospace: Evaluating thermal fatigue in composites and adhesives.
Pharmaceutical/Packaging: Assessing the stability of blister packs, capsules, or containers.
Standards Compliance
Our chambers are designed to meet major global standards for accelerated thermal testing:
IEC 60068-2-2 – Dry heat test methods for electrical equipment
