Thermal Shock Testing Lab in Faridabad

What Is Thermal Shock Testing?

Thermal shock testing evaluates the effect of rapid or successive temperature changes on a product. The test is designed to analyse the impact of specified ambient temperature changes on components, equipment, and other test specimens.

The current IEC 60068-2-14:2023 standard covers Test N: Change of Temperature and replaced the 2009 edition. It includes updated specimen temperatures, test severities, tolerances, and reporting requirements.

Thermal shock or rapid temperature-change testing may help evaluate potential concerns involving:

Cracking
Material separation
Solder joint stress
Connector failures
Seal damage
Housing deformation
Electrical malfunction
Mechanical integrity
Functional degradation

Why Is Thermal Shock Testing Important?

Modern products often contain different materials such as:

Metals
Plastics
Ceramics
Electronic components
PCB assemblies
Adhesives
Coatings
Seals

These materials may respond differently when exposed to rapid temperature changes.

A controlled thermal shock test can help engineering teams evaluate how the product responds to repeated thermal stress.

The effect of a temperature-change test can depend on factors such as:

High conditioning temperature
Low conditioning temperature
Conditioning time
Rate of temperature change
Number of cycles
Heat transfer characteristics
Thermal conductivity of the specimen materials
Rate at which the specimen itself changes temperature

PRIDE TESTING LAB can support thermal shock and temperature-change testing based on the applicable product standard, customer specification, or project requirement.

Rapid Temperature Change Testing

Rapid temperature change testing exposes a product to specified high and low temperature conditions with a defined transfer or transition requirement.

This testing may help evaluate:

Thermal stress resistance
Product integrity
Functional performance
Material compatibility
Assembly reliability
Connection stability

IEC 60068-2-14 provides methods for analysing the effects of specified ambient temperature changes on test specimens.

Thermal Cycling Testing

Thermal cycling generally involves repeated exposure to changing temperature conditions according to a defined test profile.

It may be useful for evaluating the effect of repeated expansion and contraction on:

PCB assemblies
Solder joints
Electronic components
Connectors
Cables
Seals
Housings
Mechanical assemblies

The required temperature range, dwell time, rate of change, and number of cycles should follow the applicable specification.

Temperature Change Testing

Temperature-change testing evaluates the effects of moving a specimen between specified temperature conditions.

IEC 60068-2-14:2023 specifically addresses temperature-change testing and includes defined tests for analysing the effects of specified ambient temperature changes.

It is important to distinguish this from separate high-temperature or low-temperature testing. IEC 60068-2-14 focuses on the effects of temperature changes, while separate cold and dry heat tests address effects caused primarily by exposure to low or high temperature alone.

Thermal Shock Testing Process

1. Product and Requirement Review

Before testing, relevant information may include:

Product name and model
Technical datasheet
Product dimensions and weight
Product application
Applicable standard
Required temperature range
Required number of cycles
Product operating condition
Acceptance criteria
Customer or project specification

2. Selection of the Test Method

The appropriate test method is selected according to:

Product type
Intended application
Applicable standard
Required severity
Customer specification

Relevant requirements may include IEC 60068-2-14, applicable Indian Standards, automotive specifications, railway specifications, defence-related specifications, or customer-specific test methods.

The standard edition should be confirmed before testing. IEC 60068-2-14:2023 is the current IEC edition and replaced IEC 60068-2-14:2009.

3. Test Plan Development

A thermal shock test plan may define:

High-temperature condition
Low-temperature condition
Dwell time
Transfer time or transition conditions
Number of cycles
Product configuration
Functional monitoring
Initial measurements
Final measurements
Recovery conditions
Acceptance criteria

The exact test severity should not be assumed from a generic profile; it should be taken from the applicable product or customer requirement.

4. Product Test Configuration

The test specimen is prepared according to the applicable testing method.

The configuration may consider:

Product orientation
Electrical connections
Cable arrangements
Supporting fixtures
Monitoring equipment
Operating mode
Functional parameters

Proper configuration is important because product size, thermal mass, materials, and heat-transfer characteristics can influence the temperature response of the specimen.

5. Thermal Exposure

The product is exposed to the required sequence of temperature conditions.

Depending on the test requirement, this may involve:

High-temperature exposure
Low-temperature exposure
Rapid temperature transitions
Defined transfer times
Repeated temperature cycles

The number of cycles and temperature severity are determined by the applicable test requirement.

6. Product Performance Evaluation

The specimen may be evaluated before, during, and/or after testing.

Evaluation may include:

Functional operation
Electrical performance
Visual inspection
Mechanical inspection
Structural condition
Product-specific measurements

The results should be assessed against the agreed acceptance criteria.

7. Recovery and Final Inspection

After environmental exposure, the product may be allowed to recover under conditions specified by the applicable test method.

Final evaluation may include:

Functional verification
Electrical measurements
Physical inspection
Mechanical checks
Product-specific performance evaluation

Products That May Require Thermal Shock Testing

Thermal shock testing may be relevant to a wide range of products, including:

Electronic control units
PCB assemblies
Sensors
Actuators
Connectors
Cables
Battery systems
Lighting equipment
Displays
Electrical enclosures
Automotive components
Railway equipment

Communication equipment
Mechanical and electromechanical assemblies

Temperature-change testing is widely used for components and systems exposed to fluctuating thermal environments and is relevant to products where structural integrity or functional performance under rapid temperature changes must be evaluated.

Thermal Shock Testing for Electronic Products

Electronic assemblies may contain materials with different thermal expansion characteristics.

Repeated temperature changes may place stress on:

Solder joints
PCB materials
Semiconductor packages
Connectors
Component interfaces
Protective coatings

Thermal shock testing can provide engineering information about product behaviour under the specified environmental conditions.

Thermal Shock Testing for Automotive Components

Automotive components may experience significant temperature variations during operation and storage.
