Inclined Plane Tester
Inclined Plane Tester (Product Code: SLE/ET/07) is a tilting-plane friction instrument used to determine the coefficient of friction between film and film, film and metal, and film and glass in packaging and plastics laboratories. The plane rises at 1.5° to 2.0° per second beneath a 750 gram sled measuring 4 inch × 2 inch, and two stainless steel templates are included. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory equipment exporter from India serving domestic and overseas buyers.

What Is the Inclined Plane Tester Used For?
The inclined plane method finds static friction without a force gauge. The sled, faced with the sample, rests on the plane, which tilts steadily at 1.5° to 2.0° per second until the sled starts to slide; the tangent of that angle is the static coefficient of friction between the two surfaces. Because the instrument is intended for film-to-film, film-to-metal and film-to-glass pairs, one set-up compares a packaging film against itself and against the surfaces it meets on machines and shelves.
Film converters use it to set slip specifications and check production batches, while physics and engineering courses use it to show the angle of friction on real materials. Fit the film smoothly to the 750 gram sled without creases, clean metal or glass surfaces before each run, and repeat on fresh sample areas before averaging the slip angle. Laboratories that also own the horizontal-pull Static and Kinetic Friction Tester can compare the two methods directly.

Frequently Asked Questions
Which material combinations can the Inclined Plane Tester measure?
The Inclined Plane Tester is intended to determine the coefficient of friction between film and film, film and metal, and film and glass, so a packaging film can be checked against itself and against common contact surfaces.
How fast does the plane tilt?
The plane of the Inclined Plane Tester tilts at 1.5° to 2.0° per second. A slow, steady rise lets the sled start sliding at a well-defined angle, which is then used to work out the static coefficient of friction.
What are the sled weight and size?
The Inclined Plane Tester uses a 750 gram sled measuring 4 inch × 2 inch. The film sample is fitted smoothly to the sled face before each test so that contact with the counter-surface is even.
How is the coefficient of friction worked out?
On the Inclined Plane Tester, the static coefficient of friction equals the tangent of the plane angle at the moment the sled begins to slide, so a steeper slip angle indicates a higher-friction pair of surfaces.
How does it differ from the Static and Kinetic Friction Tester?
The Inclined Plane Tester finds static friction from the angle at which a sled slips, while the Static and Kinetic Friction Tester pulls a sled horizontally and reports both static and kinetic values. Many packaging laboratories use both methods.
Who supplies the Inclined Plane Tester?
The Inclined Plane Tester is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to packaging, plastics and teaching laboratories in India and international markets.
