ASTM D5793-18(2022) PDF

Overview

ASTM D5793-18(2022) is the internationally recognized standard test method for determining the number of binding sites per unit length or width in pile yarn floor coverings. Developed by ASTM International, this standard applies to machine-made, woven, knitted, and tufted carpet and floor covering products, both before and after adhesive backing application. The method provides a consistent, reliable approach for inspecting critical construction attributes that influence both the appearance and performance of textile floor coverings.

The measurement of binding sites is essential for manufacturing quality control, ensuring consistency within and between product batches, and for commercial acceptance testing within the flooring industry.

Key Topics

• Binding Sites: Areas where pile yarn is secured to the backing of the floor covering, affecting durability and surface uniformity.
• Scope of Application: Applies to all machine-made pile yarn floor coverings, including woven, tufted, or knitted types, in both finished and unfinished (prior to adhesive application) states.
• Sampling and Conditioning: Procedures for taking representative samples from production or shipping rolls, specimen preparation, and conditioning in accordance with industry-accepted practices.
• Measurement Process: Involves physically counting binding sites over a measured length or width, ensuring repeatable results by following specified distinguishing criteria and utilizing precise tools such as graduated scales or tapes.
• Precision and Bias: The standard outlines procedures to address and rectify inter-laboratory differences, ensuring unbiased, statistically robust data for quality and cost control.

Applications

• Quality Control in Manufacturing: Helps manufacturers monitor the density and structure of pile attachment during production, directly impacting product aesthetics and performance.
• Acceptance Testing of Commercial Shipments: Provides objective, widely accepted criteria for buyers and suppliers to ensure contract compliance and product consistency upon delivery.
• Material Specification & Comparison: Assists designers and procurement specialists in comparing construction details among various floor coverings for different performance or visual requirements.
• Industry Communication: Supports standardized reporting and terminology, promoting clear communication across the flooring supply chain.
