ASTM D7506/D7506M-17 (2025) PDF

Full title and description

ASTM D7506/D7506M-17 — Standard Test Method for Pocket Reinforcement. This test method specifies procedures to evaluate localized reinforcement (bar‑tacking) around pocket areas of garments by applying grab/tensile test procedures to determine breaking strength, mode of failure and location of break in the pocket reinforcement area.

Abstract

This standard describes a grab/tensile test for assessing pocket reinforcement in apparel. A specimen containing the pocket reinforcement (bar‑tack) is clamped in a constant‑rate‑of‑extension tensile testing machine and loaded until failure. Results record breaking force, failure mode and the location of failure relative to the reinforcement. The method provides a repeatable way to compare pocket reinforcement strength across materials and constructions.

General information

• Status: Current test method in the D75xx textile suite; earlier 2012 edition shown as withdrawn/replaced by the 2017 designation in some catalogues.
• Publication date: Published as ASTM D7506/D7506M-17 (2017). (Catalog listings reference the 2017 edition; retail/title listings appear in 2025 collections as the active D7506/D7506M-17 entry.)
• Publisher: ASTM International (American Society for Testing and Materials).
• ICS / categories: Textiles / Clothing and apparel testing — ICS code related to clothes and apparel test methods (e.g., 61.020).
• Edition / version: Designation: ASTM D7506/D7506M-17 (2017 edition). Some databases list the standard under 2025 collections as D7506/D7506M-17(2025) for their catalog year.
• Number of pages: Short method (typically 3–4 pages depending on published format).

Scope

This test method provides a procedure to determine localized weakness or strength of pocket bar‑tacking and reinforcement on all types of garments (shirts, trousers, jeans, etc.). It applies grab/tensile testing to specimens containing the pocket reinforcement and is intended for use with constant‑rate‑of‑extension tensile testing machines. Results are reported as breaking force and descriptive failure information; units in either SI or inch‑pound systems are specified and treated independently.

Key topics and requirements

• Specimen preparation: selection and orientation of pocket area specimen to capture the bar‑tack or reinforcement zone.
• Test equipment: constant‑rate‑of‑extension tensile testing machine and appropriate clamps/fixtures sized for the grab specimen.
• Test conditions: specified clamp spacing, extension rate, and measurement units (SI and inch‑pound treated independently).
• Measured outputs: breaking force (tensile strength), mode of failure (e.g., fabric rupture, stitch failure, bar‑tack pullout), and location of failure relative to pocket reinforcement.
• Reporting: recorded force, units, specimen orientation, failure description and any relevant environmental or conditioning information.
• Precision and limits: short, standardized procedure intended for comparative quality control rather than long, precise material characterization studies.

Typical use and users

Used by textile and apparel manufacturers, quality control laboratories, garment designers and testing houses to verify the strength and reliability of pocket reinforcements (bar‑tacks) during production and acceptance testing. Also used by compliance teams and third‑party test labs that validate construction and performance claims for apparel products.
