The confusion starts with the number itself. ASTM standards follow a strict format: Designation (e.g., D = plastics), number, and year of publication. When someone searches “ASTM D61821 PDF,” they’re likely thinking of ASTM D618-21—the 2021 version of the Standard Practice for Conditioning Plastics for Testing. The missing hyphen? A common typo, but one with big implications. There is no ASTM D61821 standard—only a corrected, modern take on an aging protocol.

The “conditioning process” isn’t just about drying plastics. Some standards even require “aging” materials under UV light or extreme temperatures to simulate years of use in a lab. Think of ASTM D618-21 as the starting gate in this marathon of durability.

ASTM D6182-21 establishes a standardized, Bally flexometer-based method for evaluating the flexibility and adhesion of surface coatings on finished leather, specifically detecting cracking, delamination, and discoloration. The test simulates real-world stress on materials for applications like footwear and upholstery, ensuring quality control by simulating continuous flexing. For the full standard, visit ASTM International.

ASTM D6182-23 is the updated, September 2023 standard method for testing the flexibility and adhesion of finished leather coatings to resist cracking and delamination. Utilizing a Bally Flexometer at 100 cycles per minute, the test assesses finished leather used in apparel and upholstery for durability.
