Top Testing Methods Used in Synthetic Leather Analysis

As synthetic leather becomes an increasingly popular alternative to genuine leather across industries like fashion, furniture, automotive, and consumer goods, quality assurance and regulatory compliance have taken center stage. Whether you are a manufacturer, importer, or brand owner, Synthetic Leather Testing plays a crucial role in ensuring that your products are safe, durable, and compliant with industry standards.

In this blog, we’ll explore the top testing methods used in synthetic leather analysis, helping you understand what goes into verifying material quality, performance, and safety before products hit the market.

What Is Synthetic Leather Testing?

Synthetic leather testing refers to a comprehensive set of laboratory evaluations performed on artificial leather materials like PVC (polyvinyl chloride), PU (polyurethane), and microfiber-based leather alternatives. These tests assess a variety of physical, chemical, mechanical, and environmental properties to ensure that the material meets international and regional quality and safety requirements.

Why Is Synthetic Leather Testing Important?

Ensures durability and long-term performance

Prevents product recalls and customer complaints

Demonstrates compliance with REACH, RoHS, ISO, and other regulations

Validates claims like waterproofing, UV resistance, or flame retardancy

Protects consumer health and the environment

Now let’s dive into the top testing methods used in synthetic leather analysis.

1. Tensile Strength Testing

Purpose:

To measure how much pulling force a synthetic leather sample can withstand before breaking.

Method:

Performed using a universal testing machine (UTM). A rectangular test sample is clamped at both ends and pulled at a constant speed until it breaks. The force applied is recorded in megapascals (MPa).

Standards:

ISO 1421

ASTM D5034

Why It Matters:

Tensile strength testing ensures the material can endure everyday stress, especially in products like bags, footwear, and automotive seats.

2. Tear Strength Testing

Purpose:

To evaluate the resistance of synthetic leather to tearing.

Method:

A pre-cut sample is subjected to a steadily increasing force until it tears completely. This test often uses an Elmendorf tear tester.

Standards:

ISO 4674

ASTM D2261

Application:

Critical for footwear, upholstery, and other items subject to stretching or pulling.

3. Abrasion Resistance Testing

Purpose:

To determine how well synthetic leather resists wear caused by friction.

Method:

A sample is subjected to rubbing cycles using an abrasion tester (e.g., Martindale or Taber tester). The number of cycles until visible wear or damage appears is recorded.

Standards:

ISO 12947 (Martindale)

ASTM D3884 (Taber)

Why It Matters:

Essential for high-wear products like furniture, car interiors, and accessories.

4. Flex Resistance Testing

Purpose:

To evaluate the flexibility and crack resistance of synthetic leather when bent repeatedly.

Method:

Synthetic leather samples are folded repeatedly at a controlled speed and temperature. Any cracks or material failure are recorded after a specified number of flex cycles.

Standards:

ISO 32100

ASTM D2097

Ideal For:

Footwear, gloves, and automotive interiors.

5. Colorfastness Testing

Types of Colorfastness Testing:

To light (UV exposure)

To rubbing (dry and wet)

To washing or water exposure

Method:

Samples are exposed to simulated conditions (e.g., sunlight, friction, water) to assess color changes or staining on adjacent fabrics.

Standards:

ISO 105 Series

AATCC Standards

Application:

Important for fashion and upholstery applications where color retention is critical.

6. Chemical Resistance Testing

Purpose:

To evaluate how synthetic leather responds to chemicals such as solvents, acids, and oils.

Method:

Samples are exposed to common chemicals for a defined duration. Observations include discoloration, swelling, or surface deterioration.

Useful In:

Workwear, automotive, and medical upholstery where chemical exposure is likely.

7. Flammability Testing

Purpose:

To assess the fire resistance of synthetic leather.

Method:

Samples are exposed to an open flame under controlled conditions. The ignition time, flame spread, and self-extinguishing capability are recorded.

Standards:

ISO 3795 (Automotive)

FMVSS 302 (Federal Motor Vehicle Safety Standard)

Importance:

Crucial for applications in public transportation, hospitality, and automotive interiors.

8. Volatile Organic Compounds (VOC) Testing

Purpose:

To detect off-gassing or emission of harmful VOCs from synthetic leather.

Method:

Samples are heated in a sealed chamber. Emissions are collected and analyzed using gas chromatography–mass spectrometry (GC-MS).

Common VOCs:

Formaldehyde, toluene, benzene, phthalates

Required For:

Automotive interiors, home furnishings, and children's products

9. Heavy Metal and Phthalate Testing

Purpose:

To detect the presence of regulated or banned substances such as lead, cadmium, and phthalates.

Method:

Using ICP-OES, AAS, or GC-MS techniques, labs quantify heavy metal or plasticizer content against REACH and RoHS limits.

Why It Matters:

Compliance with regulations like REACH, RoHS, CPSIA, and PROP 65 is critical for global distribution.

10. Water Resistance and Hydrolysis Testing

Purpose:

To check how synthetic leather reacts to water and humid conditions over time.

Method:

Samples are exposed to high humidity and elevated temperatures. After prolonged exposure, material changes such as cracking or delamination are recorded.

Common Standards:

ISO 5423

ISO 20344 (for footwear)

Suitable For:

Footwear, outdoor gear, and marine upholstery.

11. Adhesion of Coating Testing

Purpose:

To measure how well the synthetic leather coating adheres to the backing substrate.

Method:

A cross-hatch or peel test is used to quantify coating separation under mechanical stress.

Importance:

Ensures durability and long life of coated fabrics in tough conditions.

Conclusion

As consumer expectations rise and global compliance standards tighten, synthetic leather testing becomes a non-negotiable part of the product development and quality assurance process. The above methods help manufacturers validate material performance, ensure safety, and meet regulatory requirements in a competitive global market.

By working with an ISO 17025-accredited lab that offers specialized synthetic leather analysis, you not only ensure the integrity of your product but also safeguard your brand’s reputation.
