We understand the performance of a clamp as the ability to effectively transfer the tightening torque applied to the screw or bolt to the entire surface of the clamp, from the band to the clamp over the hose or coupling.

What is the Polar Diagram Test?

The Polar Diagram Test is an essential tool for measuring the performance of a clamp. This test provides a graphical representation of the force exerted by the clamp band at eight specific points, known as sectors.

The Importance of Uniformity

The homogeneity of the results obtained in the different sectors of the Polar Diagram test is crucial. A consistent outcome between sectors indicates that the clamp is applying a balanced force around the circumference of the hose. This means that there are no unbalanced pinch points, ensuring a leak-proof seal.
