ISO 534

Paper and board — Determination of thickness, density and specific volume

Test Materials

ASTM D1777 specifies the use of textile materials such as fabrics, nonwoven textiles, and other fibrous materials. The sample should be prepared according to the standard’s guidelines to ensure uniform thickness for accurate testing.

Test Process

The test involves measuring the thickness of the textile material using a micrometer or other specified thickness gauges. The sample is placed on the testing platform, and the gauge is applied at a consistent pressure to determine the material’s thickness at various points.

Test Result Interpretation

The test results are interpreted based on the measured thickness, which is reported as the average value of multiple readings. Variations in thickness can indicate inconsistencies in material quality, which may affect the material’s performance in its intended application. The results help assess the uniformity and overall quality of the textile material.
