ASTM D5793-18 PDF Download

For the purpose of counting the number of binding sites per unit length or width of pile yarn floor coverings, ASTM D5793-18 is a standard test procedure. Due to its ability to evaluate the appearance and functionality of the floor coverings, this test method is useful in ensuring quality and cost management during the manufacturing process.

The test method exhibits acceptable estimates of between-laboratory precision, making it suitable for acceptance testing of commercial shipments. The industry uses it frequently for acceptance testing. Comparative testing should be performed in instances where there are sizable discrepancies in test results between laboratories to ascertain whether there is any statistical bias. The homogenous test samples used in these comparative tests should come from the same material lot and be distributed to the laboratories at random. The test results should be compared using statistical tests for unpaired data, and if any bias is found, its root cause should be discovered, fixed, or future test results adjusted.
