Preparing for GB/T 24218.2 Method A testing: from method to instrument setup

The Digital Thickness Gauge (TNG1089) and Fabric Thickness Tester (TNG1094) are suitable for testing in accordance with GB/T 24218.2 Method A, providing accurate and reliable thickness measurements required by the standard.

Confirming the Method Code

Before selecting an instrument, it is essential to confirm that the method code aligns with the testing requirements. GB/T 24218.2 Method A specifies the procedures for determining the thickness of nonwoven fabrics. This standard requires precise measurements to ensure the material meets quality and performance criteria. The TNG1089 and TNG1094 are both designed to meet these specifications, offering the necessary accuracy and range for the required testing.

Identifying the Required Measuring Range

The measuring range is a critical factor in selecting the appropriate instrument. According to GB/T 24218.2 Method A, the thickness of nonwoven fabrics can vary significantly, and the instrument must be capable of measuring within this range. The TNG1089 and TNG1094 both have a thickness range of 0.01~25mm, with an optional range of 0.001~25mm. This wide range ensures that the instruments can accommodate various fabric thicknesses, from very thin to thicker materials, as required by the standard.

Checking the Published Specification Table

The specifications of the TNG1089 and TNG1094 are crucial for ensuring compliance with GB/T 24218.2 Method A. The measuring accuracy of 0.01mm is essential for obtaining precise thickness measurements, which is a requirement of the standard. Additionally, the lowering speed of the pressing foot at 1.72 mm/s ensures consistent and repeatable measurements. The available pressing foot areas (100mm², 2000mm², 2500mm², 10000mm²) allow for different testing configurations, accommodating various fabric types and thicknesses. The load weights and pressing durations (10s, 30s) are also specified to meet the standard's requirements for accurate and standardized testing procedures.

Requesting a Quotation

Once the method code, measuring range, and specifications have been verified, the next step is to request a quotation. This ensures that the selected instruments meet the required standards and specifications. The TNG1089 and TNG1094 are both suitable for GB/T 24218.2 Method A, offering the necessary accuracy, range, and configuration options. By confirming these details, procurement and setup can proceed efficiently, ensuring that the testing process is both accurate and compliant with the standard.
