System Description of the SCT-01 Short Span Compression Tester

The SCT-01 Kompressionstester mit kurzer Spannweite is designed with precision clamps and a robust clamping mechanism to ensure accurate testing:

• Clamps: The tester has two clamps, each 30 mm in length, with stationary and movable jaws. These jaws are crafted with a high-friction surface to ensure firm and consistent grip during tests.
• Clamping Force: It applies a steady clamping force of 2300 ± 500 N, securely holding the test piece across its entire width.
• Jaw Alignment: The stationary and movable jaws are parallel, maintaining uniformity across each test and supporting accurate measurements.
• Pneumatic Clamping and Adjustable Test Speed: The tester’s pneumatic clamping system with customizable force and adjustable speed enables flexibility, adapting to various test requirements and material types.

Test Principle of Short Span Compression Testing

The SCT-01 Short Span Compression Tester operates on a straightforward yet reliable test principle:

• A 15 mm-wide test sample is clamped between two jaws that are initially spaced 0.70 mm apart.
• The jaws then compress the test sample until it fails under the applied force.
• The maximum force applied before the compressive failure is recorded, and this value is used to calculate the material’s compressive strength.

This method offers reliable, repeatable results, helping manufacturers determine the material’s strength in real-life application settings.
