ASTM D6283-21 PDF Download

A common test procedure used to gauge the length of the tuft element in uncoated pile yarn floor coverings is ASTM D6283-21. For the purpose of quality and cost control during the manufacturing process, the tuft length of pile yarn floor coverings is a significant element that affects both appearance and performance.

Comparative tests should be performed to ascertain whether there is a statistical bias when test results from different laboratories disagree. For these tests, homogenous test samples should be taken from the same material and distributed randomly to each laboratory in an equal number. Then, in order to detect any biases, the test results from the laboratories should be compared using a statistical test for unpaired data. Future test results should be changed if a bias is discovered, or it should be addressed.

As long as every tuft element measured is bound at the same number of binding sites, the test technique described in ASTM D6283-21 is applicable to both tuft elements bound at only one binding site and tuft elements bound at numerous binding sites. This standard offers instructions for precisely measuring tuft length and pile yarn length, providing consistency and dependability in judging the caliber of floor coverings made of uncoated pile yarn.
