Full title and description
Standard Test Method for Tensile Properties of Elastomeric Yarns (CRE Type Tensile Testing Machines). This ASTM test method specifies procedures to determine tensile parameters of “as produced” elastomeric yarns (natural rubber, spandex and other elastomers) using constant‑rate‑of‑extension (CRE) tensile testing machines, reporting properties such as force and tenacity at first filament break, elongation, work to break and toughness.
Abstract
This standard describes specimen preparation, CRE‑type tensile test machine requirements, test speeds and clamping arrangements, and the calculations used to derive tensile metrics for elastomeric yarns. It excludes covered, wrapped, core‑spun and staple‑spun elastomeric yarns and is intended for yarns in a defined linear density range. The procedure produces force‑elongation curves from which force at first filament break, tenacity, elongation at first filament break, work to break and toughness are reported.

Scope
The test method covers determination of tensile properties of as‑produced elastomeric yarns (natural rubber, spandex and similar elastomers) using CRE‑type tensile testing machines. It applies to single elastomeric yarns (not covered/wrapped/core‑spun or staple‑spun elastomeric yarns) and is typically applicable over a yarn linear density range of approximately 40 to 3200 dtex (about 36 to 2900 denier). Test outputs include force at first filament break, tenacity at first filament break, elongation at first filament break, work to break and toughness. Machine specification, clamping, test speed and calculation procedures are specified.
Key topics and requirements
- Test apparatus: CRE (constant‑rate‑of‑extension) type tensile testing machine meeting ASTM D76 performance/verification requirements.
- Specimen handling and conditioning: instructions for storing and conditioning specimens prior to testing to ensure repeatability.
- Clamping: recommended pneumatic clamping assemblies and jaw face descriptions to minimize slippage and damage to elastomeric filaments.
- Test speeds: typical pulling speed 500 mm/min (20 in/min) or 1000% extension per minute (procedural options described).
- Measured outputs: force at first filament break, tenacity, elongation at first filament break, work to break and toughness calculated from force‑elongation curves.
- Applicability limits: excludes covered/wrapped/core‑spun and elastomeric staple‑spun yarns; intended linear density range specified in the standard.
Typical use and users
Used by textile laboratories, yarn manufacturers, quality control teams and research organizations that develop or verify elastomeric yarn properties for apparel, medical textiles, hosiery, elastic trims and industrial elastomeric yarn applications. It supports product development, incoming quality inspection and specification compliance.
