Testing

We can run any test on O-rings and seals

In our O-Ring Laboratory we perform many tests for our customers.
On the right side you'll see the most common tests we perform.
Please contact us for further information.

Identity testing

Identity testing

Hardness and density are quickly and conveniently determined, making them ideal for incoming goods inspection and testing.

Hardness testing

Hardness testing

The hardness test is probably the most applied and most common test method in the elastomer industry.

Compression Set

Compression Set

This test assesses the degree to which a seal or material loses its ability to recover its original shape after undergoing specific thermal stress conditions.

Compression Set at Low Temperatures

Compression Set at Low Temperatures

This test indicates how much a seal or a material loses its recovery behaviour after predefined thermal stress.

Tension test

Tension test

The practical benefit of this test entails ascertaining the degree of cross linking of finished parts where a compression set test is not applicable.

Tensile test

Tensile test

This test is not only about physical material properties, it can reveal a lot more.

Immersion tests

Immersion tests

We conduct durability tests in oil, fuels, coolants, refrigerants, superheated steam and many more media. 

Heat ageing

Heat ageing

The thermal resistance of an elastomer ranks among its most important characteristics. However, there are different possibilities to check it.

Ozone resistance

Ozone resistance

Many elastomers may become cracked even under normal environmental ozone concentrations.

THERMOGRAVIMETRIC ANALYSES

THERMOGRAVIMETRIC ANALYSES

Thermogravimetric analysis (TGA) is one of the most commonly utilized analytical tests for elastomer materials.

DIMENSIONAL INSPECTION

DIMENSIONAL INSPECTION

The dimensional stability of seals is intimately connected to their ease of mounting and proper operation.

Sortation according to given tolerances

Sortation according to given tolerances

If the sealing measurements are inaccurate and an urgent remedy is required, then the only solution is to re-sort the components.

Visual inspection

Visual inspection

Visual inspection plays a crucial role as a safeguard due to the challenging processability.

Stress Relaxation in Compression

Stress Relaxation in Compression

During this test, the continuous measurement tracks the variation in sealing force over time, considering the impact of temperature, medium, and testing duration.

TEAR STRENGTH

TEAR STRENGTH

This test is crucial for dynamic seals, and significant variations can exist within a material category.

INFRARED SPECTROSCOPY

INFRARED SPECTROSCOPY

Ultimately, this method reveals the inherent vibrations of organic molecules, enabling the detection of functional groups, particularly in elastomers.

 

DIFFERENTIAL SCANNING CALORIMETRY (DSC)

DIFFERENTIAL SCANNING CALORIMETRY (DSC)

This calorimetric test identifies the thermodynamic glass transition of elastomers, marking the shift from energy elasticity to entropy elasticity.

TR 10

TR 10

This test utilizes a thermomechanical measurement method to observe the behavior of an elastomer throughout the entire defrosting process.

REBOUND RESILIENCE

REBOUND RESILIENCE

In applications where elastomers are used as bumpers, minimizing self-heating resulting from absorbed energy is essential.

MEASUREMENT OF ELECTRICAL PROPERTIES OF ELASTOMERS

MEASUREMENT OF ELECTRICAL PROPERTIES OF ELASTOMERS

To prevent static electricity buildup or electrochemical degradation

PYROLYSIS GC-MS

PYROLYSIS GC-MS

The analysis method with the highest resolution for obtaining indications of the ingredients present in elastomer samples. A sample size as small as 1 mg is adequate for this purpose.

Failure Analysis

Failure Analysis

For the O-Ring Prueflabor Richter the failure analysis of elastomeric seals is one of its core competences.
