Full title and description
ASTM D3513-02 (reapproved 2024) — Standard Test Method for Overlength Fiber Content of Manufactured (man-made) Staple Fiber. This test method defines a procedure for determining the percentage by number of overlength or multiple-length fibers in samples of manufactured staple fiber for quality control and specification purposes.
Abstract
This standard specifies a laboratory procedure (commonly known as a combing or fibrosampler-type method) for extracting and counting overlength or multiple-length fibers from a staple fiber sample and calculating the percent overlength by number. It applies to fibers taken immediately after manufacture, from bales, or from parallelized material and emphasizes handling that avoids stretching or damage to fibers during straightening and counting.

Scope
The scope covers the determination of the percent by number of overlength or multiple-length fibers in man-made staple fiber samples. The method is intended for routine quality control and acceptance testing of manufactured staple fibers and is applicable to samples taken at or near production (immediately after manufacture), from bales, or from parallelized sliver. It does not address other fiber properties beyond overlength/multiple-length content or safety considerations related to test execution.
Key topics and requirements
- Definition of overlength and multiple-length fibers and terminology used in length testing.
- Sample selection and preparation rules (sampling from production, bales, or parallelized material).
- Combing/collection procedure to capture overlength fibers without stretching (fibrosampler/comb technique).
- Counting and calculation method to express overlength content as percent by number.
- Reporting requirements and notation (designation/version reference and any special handling notes).
Typical use and users
Used by textile and fiber manufacturers, quality control laboratories, independent testing houses, and material specification personnel to quantify overlength/multiple-length fiber fractions in manufactured staple fibers. It supports product specification, acceptance testing, process control and troubleshooting in fiber production and downstream textile processing.
Related standards
Closely related ASTM methods and practices include standards for fiber length and length distribution (for example ASTM D5103), sampling methods for textile fibers (for example ASTM D3333 and other sampling standards), and earlier or withdrawn editions of D3513 (e.g., D3513-96). Several of these standards reference or are cross-referenced with D3513 in standards catalogs and bibliographies.

FAQ
Q: What is this standard?
A: ASTM D3513-02 is a test method for determining the percent (by number) of overlength or multiple-length fibers in manufactured staple (man-made) fiber samples.
Q: What does it cover?
A: It covers sampling contexts (production, bales, parallelized material), a combing/collection procedure to isolate overlength fibers without stretching, counting, and reporting the overlength content as a percentage by number. It is focused specifically on overlength/multiple-length content and not on broader fiber properties.
Q: Who typically uses it?
A: Textile and fiber manufacturers, QC labs, independent testing laboratories, and specification engineers use this method for acceptance testing, process control and product specification.
Q: Is it current or superseded?
A: The designation D3513-02 is the 2002 adoption that has been formally reapproved in 2024 and is treated as current in standards catalogs (often shown as D3513-02(2024) or D3513-02R24). Older editions (for example D3513-96) are withdrawn or superseded. Users should confirm the current status with ASTM or an official distributor before formal citation.
Q: Is it part of a series?
A: It is one of several ASTM test methods addressing fiber length, length distribution, and sampling for man-made (manufactured) staple fibers; related methods include ASTM D5103 (length and length distribution) and various sampling practices that together support fiber evaluation.
Q: What are the key keywords?
A: Overlength fiber, multiple-length fiber, staple fiber, man-made fibres, fibrosampler, combing method, fiber length distribution.
