ASTM D3786 FAQ: instruments, ranges and method scope
The Bursting Strength Tester (TNG1014) is designed to meet the requirements of ASTM D3786 for testing the bursting strength of flexible packaging materials.
What is the testing mode of the Bursting Strength Tester?
The TNG1014 supports multiple testing modes, including fixed-speed bursting, fixed-pressure bursting, fixed-expansion bursting, and fixed-time bursting. This versatility allows the instrument to accommodate various testing protocols required by ASTM D3786, ensuring accurate and repeatable results across different material types and test conditions.
What are the measurement ranges of the Bursting Strength Tester?
The TNG1014 has a measurement range of 0-10 MPa ±1% when using a test cup of ≤10cm², 0-3 MPa ±1% with a test cup of 50cm², and 0-1 MPa ±1% with a test cup of 100cm². These ranges are specifically calibrated to align with the pressure thresholds outlined in ASTM D3786, ensuring that the instrument can accurately measure the bursting strength of materials under standardized conditions.
What is the testing rate of the Bursting Strength Tester?
The TNG1014 operates at a testing rate of 50-500 ml/min. This controlled flow rate is essential for maintaining consistent pressure application during the bursting test, as specified in ASTM D3786. The precise control over the testing rate ensures that the material is subjected to uniform stress, minimizing variability in test results and enhancing the reliability of the data.
What is the hydraulic medium used in the Bursting Strength Tester?
The TNG1014 uses 7.HY.004 glycerin as its hydraulic medium, with a capacity of 500ml per unit. This glycerin-based fluid is chosen for its stability and resistance to temperature fluctuations, which is critical for maintaining the accuracy of pressure measurements during the test. The use of this specific hydraulic medium support testing to the fluid requirements of ASTM D3786, contributing to the precision and consistency of the testing process.
