ASTM D3936-21 PDF Download

A technique for evaluating the secondary backing used in pile yarn floor coverings' resilience to delamination is laid out in the ASTM D3936-21 standard.

It may be prudent to conduct comparative tests in cases of disagreement resulting from reported test result discrepancies since the standard is primarily utilized for acceptance testing of commercial shipments. To ascertain whether there is any statistical bias between the laboratories, the buyer and the supplier should do comparative tests in such circumstances. To do this, they should collect a set of test samples that are as homogeneous as feasible, distribute them equally throughout the testing laboratories, and then use a statistical test for unpaired data to compare the average outcomes.

This standard's objective is to assess quality and budgetary management throughout the production of pile yarn floor coverings. Delamination of the secondary backing might have an impact on the floor coverings' appearance and functionality.
