Product Overview
The DCJ-II DuPont Impact Tester (PS 2699 Series) is suitable for testing materials such as plastics, ceramics, acrylics, and fiberglass, as well as evaluating the durability of coatings. Its principle involves allowing a steel ball of a specified weight to fall freely from a certain height to impact the sample. The impact resistance of the material is then assessed by observing the extent of damage to the sample.
Product Features
1. Suitable for fastness testing of various materials and coatings.
2. Utilizes the principle of free-fall impact with a specified weight steel ball, providing an intuitive testing method.
3. Complies with multiple international and regional standards.
Working Principle
The working principle of this impact tester involves adjusting a steel ball of specified weight to a predetermined height and allowing it to fall freely to vertically strike the sample placed on the base. The material or coating's resistance to rapid deformation (impact) is evaluated by observing and assessing the extent of damage to the sample after impact, such as cracks, spalling, or deformation.
Application field
Plastics, ceramics, acrylic, fiberglass, and other materials, coatings
Complies with standards
China Taiwan Standard CNS 10756 "General Methods of Test for Paints," Japanese Industrial Standard JIS-K5400 "General Test Methods for Paints," American Standard ASTM-D2794 "Standard Test Method for Resistance of Organic Coatings to the Effects of Rapid Deformation (Impact)."
Operation Steps
1. Place the sample flat on the impact tester base.
2. Select a steel ball of the specified weight according to the testing standard requirements.
3. Raise the steel ball to the specified height and secure it.
4. Release the steel ball, allowing it to fall freely and impact the center of the sample.
5. Remove the sample, observe, and record its damage condition.
Precautions
* Before testing, ensure all components of the equipment are securely installed, especially the steel ball release mechanism.
* Select the appropriate steel ball weight and drop height according to the specific test material and standard.
* Place the sample flat, ensuring the impact point is located in the central area of the sample.
* During operation, do not place any part of your body under the falling path of the steel ball.
* Regularly inspect the surface of the steel ball for any damage to avoid affecting the accuracy of test results.
* The equipment should be placed on a stable and level surface for use.
