Paper Tensile Breaking Strength Tester Compliant with ISO 1924, ASTM D828 and TAPPI T949 Standards

The mechanical performance of paper and cardboard materials is a critical quality indicator for both manufacturing efficiency and end-use reliability. Among these properties, tensile and breaking strength play a decisive role in determining how paper behaves during production, converting, printing, and final application. The Paper Tensile Breaking Strength Tester is designed to measure the resistance of paper and board samples when subjected to a controlled tensile force until rupture. Compliance with ISO 1924, ASTM D828, and TAPPI T949 standards ensures that test results are reliable, repeatable, and internationally recognized.

Main Purpose of the Device

The primary purpose of this device is to determine the tensile strength and breaking behavior of paper and cardboard materials under standardized conditions. By accurately measuring the force required to break a sample, manufacturers can evaluate material consistency, detect weaknesses in production, and ensure that products meet defined performance requirements.

What Is the Tensile Breaking Test?

The tensile breaking test involves clamping a prepared paper or board specimen between two grips and applying a steadily increasing tensile force at a controlled speed. The test continues until the specimen breaks. During the test, key mechanical parameters such as maximum tensile force, elongation at break, and energy absorption are measured and recorded.

Importance and Objective of the Test

This test is essential for predicting how paper will perform under mechanical stress during processing and use. It helps reduce the risk of web breaks, tearing, and material failure in production lines. Additionally, tensile test results are a fundamental component of routine quality control and product development activities.

Scientific Principle of the Test

The tensile breaking test is based on fundamental principles of material mechanics, focusing on the relationship between applied force and resulting deformation. As tensile load increases, the material undergoes elastic and plastic deformation until rupture occurs. The maximum force sustained before breaking represents the tensile strength of the material.

Use of the Device

Test specimens are prepared according to the relevant standards and securely placed between the grips to prevent slippage. After setting the test parameters, the device applies tensile force automatically at a constant rate. All relevant data are captured throughout the test and presented in a clear, measurable format for evaluation and reporting.

Technical Characteristics

The tester is equipped with a high-precision load measurement system that provides accurate results across a wide force range. Consistent and controlled test speed supports full compliance with international standards. Its robust mechanical structure ensures long-term reliability in laboratory environments. Digital control and data monitoring functions allow efficient analysis and documentation of test results.
