ASTM D6613-08(2019)
(Practice)Standard Practice for Determining the Presence of Sizing in Nylon or Polyester Fabric
Standard Practice for Determining the Presence of Sizing in Nylon or Polyester Fabric
SIGNIFICANCE AND USE
5.1 The depth of color achieved in dyeing fabric according to this practice is relative to the amount of sizing in the fabric. This practice employs a chromatic staining scale from 1 to 5 which is inversely proportional to the relative amount of sizing in the fabric. A light color stain indicates a low concentration of sizing and warrants a high numerical rating, while a dark color stain indicates a high concentration of sizing and warrants a low numerical rating.
5.2 The accuracy of this practice depends upon the ability of the testing personnel to match the color of the stain to the colors in the AATCC 9 Step ChromaticTransference Scale.
SCOPE
1.1 Using a color scale of 1 to 5, this practice describes the procedures for determining the presence and relative amount of sizing in fabrics made of undyed nylon or non-cationically dyeable polyester yarns prepared with a cationically dyeable sizing
1.2 Procedures and apparatus other than those stated in this standard may be used by agreement of purchaser and supplier with the specific deviations from the standard acknowledged in the report.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D6613-08(2019) is the internationally recognized standard practice for determining the presence and relative amount of sizing in nylon or polyester fabrics, particularly fabrics made from undyed nylon or non-cationically dyeable polyester yarns that have been prepared with a cationically dyeable sizing. Developed by ASTM International, this standard provides clear procedures for evaluating extractable sizing substances in textile fabrics, helping manufacturers and buyers assess material treatment and quality.
Textile sizing, especially on industrial fabrics such as those used for inflatable restraints, affects dyeing performance and subsequent product processing. By using a defined chromatic staining scale and standardized methodology, ASTM D6613-08(2019) ensures consistent, reliable testing for sizing residues.
Key Topics
Color-Based Sizing Evaluation
The test uses a color scale from 1 to 5, inversely reflecting the amount of sizing in the fabric. Light staining indicates low sizing content (high class rating), while dark staining signals a high presence of sizing (low class rating).AATCC Chromatic Scale Application
Test results rely on visually matching the stain color of the dyed specimen to the AATCC 9 Step Chromatic Transference Scale. The ability of testing personnel to accurately assess this visual match is crucial for reliable results.Sampling and Reporting Requirements
The standard outlines robust sampling procedures, including destructive testing and lot acceptance criteria. It details necessary data for lab reports, such as fabric designation, number of specimens, class ratings, and any deviations from standard practice.User Responsibility for Safety and Compliance
Users are responsible for establishing appropriate safety, health, and environmental practices, and ensuring compliance with relevant regulations when using this textile testing standard.
Applications
The ASTM D6613-08(2019) standard is highly valuable for organizations involved in:
Textile Manufacturing and Processing
Ensuring quality control of nylon and polyester fabrics, especially those destined for industrial applications where residual sizing impacts performance, such as automotive airbags and technical textiles.Textile Dyeing Operations
Evaluating and verifying the removal of sizing agents to ensure optimal dye uptake and consistent coloration in further processing.Purchasing and Supply Chain Management
Providing a common, standardized approach for suppliers and purchasers to agree on fabric quality and release criteria, supporting clear communication and effective material acceptance for commercial shipments.Laboratory and Quality Assurance Testing
Standardizing laboratory methods for measuring sizing levels, facilitating reliable inter-laboratory comparisons and compliance with material specifications.
Related Standards
For comprehensive textile testing and terminology, users of ASTM D6613-08(2019) should also be familiar with:
- ASTM D123: Terminology Relating to Textiles
- ASTM D6799: Terminology Relating to Inflatable Restraints
- AATCC Evaluation Procedure #8: For use with the AATCC Chromatic Transference Scale
Following these standards in conjunction with ASTM D6613 ensures consistency and interoperability across the textile industry. This alignment supports both product quality and regulatory compliance in a global marketplace.
By adopting ASTM D6613-08(2019), textile professionals benefit from a clear, standardized methodology for determining sizing residues in nylon and polyester fabrics, supporting quality assurance, regulatory reporting, and optimized production outcomes.
