The Slide Angle Coefficient of Friction Tester 32-25 provides static coefficient of friction testing using the inclined plane method and conforms to a large number of stringent standards from ASTM, TAPPI and ISO.
Designed for precision static friction testing of films, paper, and sheet materials
Developed by TMI Büchel , our paper and flexible packaging testing brand, this Slide Angle Coefficient of Friction (COF) inclined plane device is ideal for testing a wide range of paper, plastic film, packaging films, paperboard, corrugated and other sheet like materials.
Our Slide Angle Coefficient Of Friction (COF) Tester is designed for static friction testing using the inclined plane method and is built to conform to a large number of stringent standards from ASTM, TAPPI and ISO.
A friction tester, also called a coefficient-of-friction (COF) tester, is used for measuring sheet-like substrates. It does this by determining the angle of inclination at which one substrate affixed to a sled will begin to slide/slip against the surface of another substrate of a similar material.
Using the Slide Angle Coefficient of Friction (COF) Tester 32-25 features a motorized inclined plane by its electric motor at a rate of 1.5 ± 0.5º per second until the test block begins to slide. The initial movement of the sled reveals the slide angle or coefficient of static friction of the material.
When the test block begins to slide a photo-optical sensor automatically stops the inclined plane so you can read the slide angle result.
A variety of factors can affect the slide angle measurements including abrasion, coatings, varnishes, printing and most importantly humidity.
The Slide Angle Coefficient of Friction (COF) Tester 32-25 measures slide angle or coefficient of static friction 0 to 80 degree angle. A horizontal plane method is also available to measure static and kinetic coefficient of friction.
Whether you work with plastic films, packaging, paper, labels, coatings, cartons, adhesives, foils or printed materials, his device is ideal for ensuring product performance, consistency, and compliance.
This COF tester is designed for reliable testing to meet our coefficient of friction tests to the most stringent of international standards, including:
In the Industrial Physics portfolio includes a wide selection of instruments designed for all types of friction testing applications.
Also from TMI Büchel , our Coefficient Friction/Peel Tester 32-76e offers unparalleled performance and flexibility to test across a wide range of standards for both COF, peel/adhesion and heat seal applications.

The Slide Angle COF Tester 32-25 is designed for measuring the static coefficient of friction of sheet-like materials using the inclined plane method. It’s ideal for paper, plastic films, packaging films, paperboard, corrugated materials, and similar substrates.
The device gradually increases the incline of a motorized plane at a controlled rate (1.5 ± 0.5º per second). A sample is mounted on a sled and placed on the inclined plane. When the sled begins to slide, the angle at which it moves is recorded as the static coefficient of friction.
This Slide Angle COF Tester 32-25 is ideal for:
The Slide Angle COF Tester 32-25 conforms to several key international standards, including:
Yes. It is designed for consistent, fast testing, making it suitable for both lab use and in-line quality control in manufacturing settings.
Poor calibration services → Selected Industrial Physics as a service partner → Superior service achieved! ✓
Proper calibration of your inspection devices is essential for a long and accurate life of service. A leading pet food manufacturer discovered this when shoddy servicing created a raft of problems with their burst and creep testing equipment.
Our experts quickly identified and rectified the pre-existing problems. Now, they’re delighted to rely upon a trusted test and inspection partner with Industrial Physics.
Scott Chambers, Quality Technician at Mars Inc., said,
“I was very happy to be one of the first companies to participate in the mobile calibration program. Ryan Moreno was my technician and was very personable, knowledgeable, and accommodating. The calibrations he performed were very efficient. I like having a technician on site one on one to answer any question I had. Also, not having to ship my BT-Integra units was a major plus. looking forward to future visits at Mars Petcare KKC.”
