ASTM D6840-02(2021) PDF

Overview

ASTM D6840-02(2021) - Standard Test Method for Effect of Drycleaning on Buttons establishes a methodology to evaluate how drycleaning impacts certain physical properties of buttons. This widely referenced ASTM International standard applies to a broad assortment of button materials, including plastics, natural substances, cast and stamped metals, as well as electroplated plastics. The main objective is to determine whether buttons retain their functional and aesthetic qualities following exposure to commercial drycleaning processes, making it essential for garment manufacturers, button suppliers, and quality assurance professionals throughout the textile and apparel industries.

Key Topics

• Physical Properties Tested:
  • For plastic and natural material buttons: assessment of color change, color transfer, solubility, swelling, and loss of finish
  • For metal and electroplated buttons: examination of color change, oxidation, and color transfer
• Sample Selection & Testing:
  • Random samples are drawn from production lots to ensure representative testing
  • Buttons are measured before and after three drycleaning cycles to detect any dimensional or visual changes
• Evaluation & Reporting:
  • Reports document measurements, visual differences, and any signs of degradation
  • Comparative laboratory tests are recommended to detect and adjust for potential statistical biases
• Standardized Procedures:
  • Use of specific reference fabrics and drycleaning procedures ensures consistency and repeatability in laboratory evaluations

Applications

Practical Uses of ASTM D6840-02(2021):

• Quality Control in Apparel Manufacturing: Ensures buttons maintain performance and appearance after drycleaning, helping prevent product returns and reinforcing brand reputation.
• Acceptance Testing for Suppliers: Provides a reliable baseline to judge batch consistency in commercial button shipments before integration into high-value garments.
• Product Development: Supports the selection of button materials and finishes that withstand multiple drycleaning cycles, essential for luxury, tailored, and uniformed apparel.
• Compliance with International Standards: Assists manufacturers in meeting quality expectations and technical barriers in global markets, aligning with WTO requirements for standardized testing.
