Scope

GB/T 8949-2025 is the English-translated version of 聚氨酯人造革.

GB/T 8949-2025 covers polyurethane artificial leather, the material sold as polyurethane leatherette, and applies to its production, inspection and sale.

It takes its terms and definitions from GB/T 34443 and sets the classification by backing fabric variety, the deviations allowed on thickness, width and length, the number of segments per roll with the minimum segment length, the appearance, and the further performance that supplier and buyer agree for a given field of use.

It describes the test methods, from cutting a 1 m specimen to tensile load and elongation at break, tearing load, peeling load and colour fastness to dry and wet rubbing, and it sets the inspection rules and the marking, packaging, transport and storage.

It replaces GB/T 8949-2008, was issued on 31 October 2025 and has applied since 1 May 2026.

3 Terms and definitions

The terms and definitions defined in GB/T 34443 apply to this document.

4 Classification

See Table 1 for classification by backing fabric variety.

5 Requirements

5.1 Specifications

5.1.1 Thickness deviation

The thickness deviation shall conform to the specifications in Table 2.

5.1.2 Width deviation

There shall be no negative deviation.

5.1.3 Length deviation

There shall be no negative deviation.

5.1.4 Number of segments per volume and minimum segment length

The number of segments per roll and the minimum segment length shall comply with the provisions of Table 3.

5.3.2 Negotiated product performance

The negotiated performance of the products shall be determined by the supplier and the buyer based on the application field of the products, and the recommended indicators shall comply with the provisions of A.1 in Appendix A.

6 Test methods

6.1 Specimen preparation

A 1 m sample is cut from the product along the lengthways direction. After removing 50 mm from each of the transverse ends of the sample, the specimen is prepared. The specimen dimensions and quantity are shown in Table 6.

6.3.3 Length deviation

Use appropriate measuring tools or instruments to perform the measurement, subtract the nominal value from the measured value to calculate the deviation, and the result shall be accurate to 1 cm.

6.3.4 Number of segments per roll and minimum segment length

Use appropriate measuring tools or instruments to perform the measurement.

6.4 Appearance

Visually inspect under natural light or a standard color assessment cabinet with a D65 light source, and measure the defect size using appropriate measuring tools.

6.5 Tensile load and elongation at break

The test shall be conducted in accordance with the provisions of Method A in GB/T 38612-2020.

6.6 Tearing load

The test shall be conducted according to GB/T 16578.1, with a test speed of (200±20) mm/min. The maximum value of the specimen shall be recorded, and the test results shall be expressed as the arithmetic mean of three specimens each in the lengthways and transverse directions, accurate to 0.1 N.

6.7 Peeling load

The test shall be conducted in accordance with GB/T 8808, at a test speed of (200±20) mm/min. The maximum value of the specimen shall be recorded. The test result shall be expressed as the arithmetic mean of three specimens each in the longitudinal and transverse directions, accurate to 0.1 N. If the peel layer or the backing fabric breaks during the test, the maximum value of the test result shall be recorded.

6.8 Color fastness to rubbing

6.8.1 Dry friction

The test shall be conducted in accordance with the provisions of GB/T 3920, and the poorer result of the two specimens shall be taken as the test result. […]

6.8.2 Wet friction
