ASTM D5823-19 PDF Download

An accepted test procedure for determining the tuft height of pile floor coverings is ASTM D5823-19. This test method is useful for keeping an eye on quality and budgetary management throughout the production of pile yarn floor coverings. Tuft height must be kept constant because it can affect the floor covering's appearance and functionality.

The buyer and the supplier are urged to do comparison tests to check for statistical bias between their laboratories in the event of any disagreements regarding the test findings. For the purpose of examining any bias, it is advised to look for qualified statistical aid. The two parties should choose a set of test samples that are as uniform as possible and distribute them at random to each laboratory for analysis. Statistical techniques, such as the Student's t-test, should be used to compare the average results from the two laboratories at an appropriate probability level.

The ASTM D5823-19 test technique calls for employing a grooved specimen holder to measure the tuft height. Following the use of adhesive backing to bind the pile yarn to the backing fabric, it is suited to both cut-pile and loop-pile floor coverings. This standard offers instructions for precisely measuring the tuft height, a crucial factor in the quality assurance of pile floor coverings.
