What is a COF Tester?
The Coefficient of Friction Tester or COF tester is used to measure the coefficient of static and dynamic friction of plastic films, foils, and similar materials. The COF tester measures the coefficient of friction of a test sample by dragging a weighted thread across the test sample to measure the force. The COF tester includes an electric test stand, a digital force gauge, a weighted COF thread, and a COF table. The COF tester features a wide speed range of 10 to 305 mm / min and a long stroke of 230 mm and is compliant with various COF test standards.
A friction Tester is a type of test equipment used to measure the coefficient of friction (COF) of a material. Generally, there are two kinds of coefficients: static coefficient of friction and kinetic coefficient of friction.
The COF or Coefficient friction testing is highly valued for its role in the processes of production, transportation, and marketing of different products.
The coefficient of the Friction tester conforms to the multiple national and international standards:
ASTM D1894 – Standard Test Method for Static and Kinetic Coefficients of Friction for Plastic Film and Sheeting
ASTM D202 – Standard Test Methods for Sampling and Testing Untreated Paper that is used for Electrical Insulation
ASTM D4918 – Standard Test Method for Coefficient of Static Friction for Uncoated Writing and Printing Paper by Using the Inclined Plane Method (Withdrawn 2010)
ISO 8295 – The materials that determine the coefficients of friction are plastics, film, and sheeting
TAPPI T815 – Coefficient of static friction (slide angle) of packaging and packaging materials which includes shipping sack papers, corrugated and solid fiberboard
TAPPI T816 – Coefficient of Static Friction of Corrugated and Solid Fiberboard
Understanding coefficient of friction testing
The Coefficient of Friction Testing COF is tests commonly carried out two know what happens when two materials rub against each other. This particular test is carried out on various kinds of materials. This is a simple test that can be carried out in both kinetic and static states.
What is a Bursting Strength Tester?
The quality of packaged products is very important in the global market. Products you purchase, such as food, consumer goods, and industrial products, must be packed and sealed in safe packaging that is highly tolerant of shipping and delivery. The paper or corrugated board used for packaging must withstand temperature and pressure fluctuations, as well as shipping fluctuations, to reach customers undamaged. There are several factors used to calculate the strength and quality of the corrugated board used for packaging, and the burst factor and strength are one of them.
A bursting strength tester machine is a reliable indicator of the strength and performance of different materials. The Bursting strength tester machine is ideal for testing a wide range of materials to determine their quality, strength, and performance. It is easy to use. It is scientifically calibrated for its reliability. It is widely used by industries and organizations and establishes itself as a proven and reliable device.
This test instrument can easily be used to determine the explosive strength of various products such as paper, cardboard, corrugated boxes, etc. This tester will work on the principle that when hydrostatic pressure is applied to the product, it will inflate. Therefore, by using the burst strength test, you can determine the strength of the packaging material.
Features of Burst Strength Tester Machine
- A precise and reliable machine
- Solid texture.
- A properly matched motor for constant pumping speed for better performance, eliminating manual errors
- Three spare rubber diaphragms and a hydraulic fluid bottle are supplied with the machine.
- All replaceable parts are available.

The paper or corrugated board used for packaging must withstand temperature and pressure fluctuations, as well as shipping fluctuations, to reach customers undamaged. There are several factors used to calculate the strength and quality of the corrugated board used for packaging, and the bursting strength tester is one of them.
This tester is mainly used in the packaging industry to calculate the strength and quality of various packaging materials such as paper, corrugated board, fiberboard, and paperboard. With proper burst strength testing of the material, manufacturers can easily guarantee the high quality of the packaging they provide to their customers.
