NZD-01 MIT Folding Endurance Tester

Introduction to the MIT Folding Endurance Tester

The MIT Folding Endurance Tester, specifically the NZD-01 model, is a reliable and precise instrument designed to assess the fold endurance of sheet materials, including paper, cardboard, and tobacco sheets with thicknesses of up to 1.25 mm. Fold endurance testing is essential for industries where materials undergo frequent bending and folding, making it a vital tool for quality control in packaging, paper production, and even textile and tobacco manufacturing. The NZD-01 MIT Folding Endurance Tester’s advanced features and adherence to international standards make it an ideal choice for manufacturers and researchers focused on material durability.

Why MIT Folding Endurance Testing Matters in Quality Assurance

Fold endurance is a critical indicator of a material’s ability to withstand repeated bending without tearing or weakening. The MIT Folding Endurance Tester provides accurate fold endurance values, reflecting the durability of a material. Materials with higher fold endurance values show greater resistance to folding stress, which can significantly influence the performance and longevity of final products. By using the MIT Folding Endurance Tester, manufacturers can make data-driven decisions in selecting materials that will perform well in real-world applications.

Overview of ISO 5626 Standard: Ensuring Consistency in Folding Tests

The MIT Folding Endurance Tester complies with ISO 5626, a standard that outlines the method for determining the folding endurance of paper and related materials. This international standard ensures consistency in test procedures across industries, setting guidelines on how to prepare samples, apply folding tension, and measure fold endurance. Under ISO 5626, samples are double-folded until they reach the breaking point, with the results indicating a material’s endurance to folding. By meeting ISO 5626 standards, the MIT Folding Endurance Tester helps businesses adhere to global testing protocols and maintain high-quality benchmarks in their materials.

Test Principles and Operation of the MIT Folding Endurance Tester

The testing procedure begins with carefully clamping the sample in the instrument’s folding jaws. The specimen is held securely in one plane and tension is applied, typically around 9.81 N, which simulates real-world forces on the material. The folding head moves back and forth, applying double-folds until the sample fractures. Once the test is complete, the counter automatically stops, recording the number of double folds required for the material to break. This number represents the fold endurance of the sample, providing crucial insights into its durability under bending stress.
