A high-quality and reliable crimp connection is at the heart of every cable assembly. Proper pressing of the contacts onto the strands ensures a long-lasting, gas-tight, and secure connection that can withstand even the most demanding conditions. With cable pull-out tests, Otto Schoch AG offers a professional method for checking the mechanical strength and quality of your crimp connections – in accordance with international standards and the highest requirements.

Why are cable pull-out tests so important?

During the crimping process, insufficient or excessive pressing force can cause serious problems:

• Insufficient pressing: If insufficient force is applied or an oversized crimping tool is used, oxygen can penetrate the fine-wired conductors. This leads to corrosion, increased contact resistance and potential loosening of the connection.
• Excessive compression: Excessive compression or a crimping tool that is too small can impermissibly reduce the cross-section of the conductors, reduce the current carrying capacity or even shear off individual conductors. This can render the connection unusable and endanger safety.

Cable pull-out tests measure the mechanical force required to separate a crimp connection. This ensures that the connection meets international standards and provides an optimal hold.

When are cable pull-out tests required?

We recommend performing pull-out tests in particular:

• For new connections: At the beginning of a project to test the quality of new cables, contacts, and tools.
• After tool changes: To ensure that new tools work correctly and meet standards.
• When changing materials: Different materials can affect the crimping result.
• For regular quality control: To detect deviations or wear in the production process at an early stage.

Our method – precision and reliability

Otto Schoch AG tests your crimp connections using the most modern processes and equipment. Our cable pull-out tests include:

• Measurement of the separation force: Determining the mechanical force required to disconnect the connection.
• Testing for international standards: Ensuring that the connection meets the applicable standards and specifications.
  
  

We also recommend a cross-section analysis

• Extraction test in combination with cross-section analysis: For a comprehensive evaluation of crimp quality and optimisation of tools, contact sizes and wire cross sections.

Your advantages at a glance

• Safety and reliability: Prevent failures due to inadequate connections.
• Quality assurance: Ensure that your crimp connections meet international standards.
