Innovative Test Solutions is ISO/IEC 17025 accredited to conduct DIN 25201 Junker testing on bolted joints of all sizes.

Junker testing is considered to be the most rigorous testing service for bolted joints.

What is Junker Testing?

A Junker test is a mechanical study that evaluates the self-loosening behavior of bolted joints. It is a pivotal testing process as the loosening of bolted joints have been problematic since their first appearance.

This process is achieved by subjecting the joint to dynamic shear loading which is caused by transverse vibration.

The goal of Junker testing is to determine how many cycles at which the joint loses preload. This information allows engineers to specify the safety and quality of joints that will fully meet their application standards.
