System Description of the SCT-01 Short Span Compression Tester

The SCT-01 Short Span Compression Tester 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.

Overview of ISO 9895 and Its Test Methods

The SCT-01 Short Span Compression Tester meets the ISO 9895 standard, a globally recognized benchmark for assessing the short-span compressive strength of paper and board.

• Introduction to ISO 9895: ISO 9895 specifies procedures for determining compressive strength, guiding the setup and testing process to ensure consistency across different labs and industries.
• Test Method Requirements: ISO 9895 outlines the dimensions of test pieces, specific clamping forces, clamping speed, and calculations for compressive strength, enabling standardized testing for accurate, comparable results.
• Importance of ISO 9895 Compliance: Compliance with ISO 9895 guarantees that the SCT-01 provides dependable, accurate compressive strength measurements, crucial for industries aiming to meet international quality and durability standards.
