ASTM D1335-21 PDF Download

The method for determining the force necessary to remove or break a tuft from a sample of a pile floor covering is described in the ASTM D1335-21 standard.

According to the standard, this test method is utilized for commercial pile yarn floor covering shipments' acceptance testing. Additionally, it implies that in cases of disagreement brought on by variations in reported test results, comparative tests can be carried out. These comparison tests entail testing homogenous samples from the same batch of material by both the supplier and the buyer, then comparing the average results using the right statistical analysis.

The guideline underlines the significance of tuft bind in preserving a pile yarn floor covering's original appearance and functionality. In the case of floor coverings made of cut pile yarn, insufficient tuft bind might result in the complete loss of pile in regions subject to extreme wear or in the production of ugly, potentially dangerous long loops.
