ASTM D3776 tester models and their published ranges
The TNG1103 Fabric Scale and TNG1104 Pneumatic Sample Press are both designed to meet the requirements of ASTM D3776 for GSM testing, with each instrument contributing uniquely to the accuracy and reliability of the test process.
Instrument Overview and Standard Compliance
ASTM D3776 outlines the procedures for determining the GSM (grams per square meter) of textile materials. This standard is crucial for quality control in the textile industry, ensuring that fabric samples meet specified weight requirements. The TNG1103 Fabric Scale and TNG1104 Pneumatic Sample Press are specifically engineered to support this standard, providing precise and repeatable measurements.
The TNG1103 Fabric Scale is designed for direct measurement of fabric weight. It has a maximum capacity of 3.5kg, which allows for the accurate weighing of a wide range of fabric samples. The scale also operates on a power supply of 220/110 V at 50/60 Hz, ensuring compatibility with various electrical systems. The length of the scale is 210 mm, which is suitable for handling standard fabric samples without compromising measurement accuracy.
The TNG1104 Pneumatic Sample Press is used to prepare fabric samples for testing by applying a controlled pressure. It has a maximum pressure capacity of 0.5-0.6 Mpa, which ensures that the fabric is uniformly compressed without causing damage. The length of the press is 400 mm, allowing for the proper placement and compression of larger fabric samples. Both instruments are referenced in ASTM D3776, with the TNG1103 aligning with ISO 3801/2286-2 and the TNG1104 with ISO 3801.
Technical Specifications and Their Role in Testing
The specifications of each instrument are critical to their performance in meeting ASTM D3776. The TNG1103 Fabric Scale's 3.5kg capacity ensures that it can handle the weight of most fabric samples, while its 210 mm length provides a stable base for accurate measurements. These features are essential for obtaining consistent results during GSM testing.
The TNG1104 Pneumatic Sample Press's 0.5-0.6 Mpa pressure range is specifically chosen to apply the necessary force to compress the fabric without altering its structural integrity. This controlled compression is vital for achieving uniform sample preparation, which is a key requirement of ASTM D3776. The 400 mm length of the press allows for the proper alignment and compression of larger samples, ensuring that the test results are representative of the material's true GSM.
Conclusion and Instrument Comparison
Both the TNG1103 Fabric Scale and TNG1104 Pneumatic Sample Press are essential tools for conducting GSM testing in accordance with ASTM D3776. The TNG1103 provides accurate weight measurements, while the TNG1104 ensures proper sample preparation. Together, they form a complete solution for meeting the stringent requirements of the standard. Each instrument's specifications are tailored to support the testing process, ensuring reliable and repeatable results.
