Full title and description

SAE J948-2023 — Test Method for Determining Resistance to Abrasion of Automotive Bodycloth, Vinyl, and Leather, and the Snagging of Automotive Bodycloth. This SAE recommended practice specifies laboratory test procedures used to evaluate abrasion resistance and snagging for materials commonly used in automotive interiors.

Abstract

SAE J948-2023 defines standardized test methods, apparatus setup, specimen preparation, test conditions and reporting formats for measuring fabric, vinyl and leather performance against abrasion and snagging relevant to vehicle interior applications. The standard is intended to produce repeatable, comparable results for material selection, supplier qualification and quality control.

Scope

Defines laboratory procedures for evaluating resistance to abrasion and snagging of automotive bodycloth, vinyl and leather used in vehicle interiors. The scope covers required test apparatus, specimen mounting and tension, abrasive media and stroke parameters, cycle counts, post-test evaluation (visual rating, mass loss or breakdown criteria), and reporting requirements so that results are comparable across laboratories and suppliers. The methods are commonly used with Wyzenbeek-style abrasion apparatus and similar tribometers referenced in related test methods.

Key topics and requirements

• Defined purpose: quantify abrasion resistance and snagging tendency of interior fabrics, vinyls and leathers.
• Apparatus and setup: specification of abrasion head/platform geometry, counterface media, clamps and sample holders (Wyzenbeek-type parameters frequently referenced).
• Specimen preparation: sample size, conditioning (temperature/humidity), tension and mounting instructions.
• Test parameters: stroke length, oscillation rate, applied load/pressure, abrasive medium, and number of cycles to be applied.
• Assessment criteria: visual ratings, change in appearance, seam failure, hole formation, mass loss or other acceptance criteria and how to record results.
• Snagging test method: procedures to provoke and rate snag formation on fabric surfaces.
• Reporting: required data fields, environmental conditions, apparatus identification, and any deviations from the standard method.

Typical use and users

Used by automotive OEMs, interior materials suppliers, independent test laboratories, component engineers and quality assurance teams to select materials, validate supplier claims, qualify production lots and investigate field complaints related to wear and snagging of interior trim. Research and development groups also use the method during material formulation and coating trials.

Related standards

Commonly referenced companion and comparable standards include ASTM D4157 (Wyzenbeek abrasion), ASTM D3597, FED‑STD‑191/5304, SAE J1530 and OEM or manufacturer procedures (e.g., GM 2756M, Toyota test methods). ISO Martindale abrasion standards (ISO 12947 series) and various national textile test standards are also related for comparative laboratory work. These related methods are often cited where specific apparatus or acceptance criteria differ.

FAQ

Q: What is this standard?

A: SAE J948-2023 is an SAE recommended practice that specifies laboratory test procedures to determine the resistance of automotive bodycloth, vinyl and leather to abrasion and the tendency of bodycloth to snag.

Q: What does it cover?

A: It covers required apparatus, specimen preparation and conditioning, test parameters (stroke, load, cycles), evaluation and reporting of abrasion and snagging tests so that results are repeatable and comparable across laboratories. The document is framed for interior materials used in road vehicles.

Q: Who typically uses it?

A: Automotive OEMs, trim and material suppliers, independent test labs, and QA/R&D engineers use the standard for material selection, supplier qualification, production quality control and failure analysis.

Q: Is it current or superseded?

A: The 2023 edition is listed as the current active edition and supersedes previous editions (for example, the 2017 edition). Users should confirm they have the 2023 revision when procuring the document.

Q: Is it part of a series?

A: J948 is a standalone SAE test method focused on abrasion and snagging of interior materials but is often used alongside other material and durability standards (ASTM textile abrasion methods, other SAE materials procedures and OEM-specific test protocols) for comprehensive material evaluation.
