HOSE CLAMP PERFORMANCE
The performance of a hose clamp is measured using a Polar Diagram.
The final result of the Polar Diagram is a graphic representation of the force exerted by the hose clamp on each sector of the dynamometer.
The diagram quantifies in daN the force which the clamp exerts on each of the 8 sectors, allowing the performance of the clamp to be evaluated. The most important aspect to be taken into account is the uniformity of the results. Ideally, all sectors of the clamp should exert a uniform force around the circumference of the band, without the appearance of peaks or troughs which would indicate potential for leaks.
