GME 60288 Abrasion Test for Textile Fabrics - Martindale Abrasion Test

Developed by General Motors Europe (GME), the “GME 60288 Abrasion Test for Textile Fabrics - Martindale Abrasion Test” standard is a materials testing standard that defines the Martindale abrasion test to evaluate the abrasion resistance of textile fabrics used in automotive applications. This standard is primarily designed for materials used in vehicle interiors, including seat upholstery, door trim fabrics, headliners, armrests, and other textile-covered components.

The primary purpose of the GME 60288 standard is to determine a textile material's resistance to wear caused by repeated friction during normal vehicle use. This standard helps engineers assess whether a fabric can withstand the following factors for many years:

• Passengers getting on and off the vehicle
• Sliding movements of the seats
• Friction caused by clothing.
• Contact with luggage and personal belongings
• Continuous daily use

Tests ensure that automotive textiles maintain both their appearance and functional performance throughout the vehicle's expected lifespan.

The GME 60288 standard applies to textile materials used in automotive interiors. These materials include:

• Woven fabrics
• knitted fabrics
• Seat cover materials
• Door panel fabrics
• Ceiling fabrics
• Fabric laminated flooring components
• Upholstery textiles

This standard may also apply in the following cases:

• Material availability
• Supplier approval
• Production quality control
• Product development
• Comparative evaluation of different fabric structures.

The Martindale abrasion test method is one of the world's most widely accepted abrasion resistance tests for textiles. The tests generally follow these steps:

• Circular samples are cut from the textile.
• Each sample is mounted on a Martindale abrasion tester.
• A standard abrasive material (typically wool cloth or abrasive paper, depending on test requirements) is rubbed against the sample.
• The sample follows a controlled Lissajous motion, generating multi-directional friction that closely simulates real-life wear. (Lissajous motion is a complex, figure-eight-like motion created by combining two perpendicular oscillatory motions. In textile testing, Lissajous motion allows the test sample to be subjected to wear from many different directions rather than repeatedly rubbing along the same path.)
• The test continues for a specified number of wear cycles.
• The equipment is periodically inspected for damage.

Depending on the material specification, typical evaluation includes the following:

• Surface wear
• Thread breakage
• Fabric tearing
• Pubescence
• Hair formation
• Loss of surface texture
• Change in appearance
• Discoloration due to abrasion

Acceptance limits are typically defined in the relevant General Motors material specification, not in the test method itself.

Tests are generally performed using a Martindale wear testing device, which includes the following:

• Sample holders
• Standardized loading weights
• Abrasive material retainers
• Cycle counter
• Standard abrasive fabric or abrasive environment
• Inspection equipment for visual assessment.

Proper sample preparation and environmental conditioning are essential for obtaining reproducible and comparable results.

In general, the workflow in testing includes the following:

• Conditioning of textile samples under controlled laboratory conditions.
• Samples must be cut to the specified dimensions.
• The samples are mounted on the Martindale testing machine.
• Application of the required test load.
• Running the specified number of wear cycles.
• Samples are examined at predetermined intervals.
• Recording wear characteristics and failure points.

Vehicle interior textiles are subjected to thousands of wear events over the life of a vehicle. Insufficient wear resistance can lead to:

• Premature wear and tear of the fabric
• Visible holes
• Wear
• Loss of aesthetic quality
• Customer complaints
• Increased warranty costs

General Motors mandates the GME 60288 standard to ensure that interior fabrics maintain their appearance and durability under long-term use. This standard is commonly used by:

• Automotive original equipment manufacturers
• First-tier seat manufacturers
• Textile suppliers
• Interior trim manufacturers
• Automotive materials testing laboratories
• Research and development centers

Although this standard was developed for General Motors Europe, the Martindale wear method is widely accepted in the automotive and textile industries.

The benefits of complying with the GME 60288 standard are as follows:

• Objective measurement of wear resistance.
• Increasing the durability of interior materials.
• Better comparison of textile products.
• Improved quality control.
• Supporting supplier qualifications.
• Reducing the risk of premature material failure.
• Improved customer satisfaction

The GME 60288 standard is based on the internationally accepted Martindale wear testing principles and is closely related to the following standards:

• ISO 12947 Textiles - Determination of abrasion resistance of fabrics by the Martindale method.
• ASTM D4966 Standard test method for abrasion resistance of textile fabrics (Martindale abrasion tester method)
• Various original equipment manufacturer (OEM) specific textile wear specifications used by automotive manufacturers.

In conclusion, the GME 60288 standard is a key standard for evaluating the abrasion resistance of automotive textile materials using the Martindale test method. It provides a consistent and repeatable procedure for assessing how well upholstery and interior fabrics withstand repeated mechanical wear. This standard contributes to the long-term quality, comfort, and appearance of vehicle interiors, supporting supplier competence and product development by ensuring textile materials meet defined durability requirements.
