GB/T 8949-2025Polyurethane leatherette (English PDF)

1 Scope

GB/T 8949-2025 is the Chinese national standard covering PU synthetic leather - the coating and the base, the strength and the peel adhesion, the hydrolysis resistance that decides whether the surface crumbles after a few years in a humid climate, the flex and the abrasion. It replaces GB/T 8949-2008, with the PVC standard GB/T 8948-2025. In force from 1 May 2026. Issued on 31 October 2025, it has been in force since 1 May 2026, replacing GB/T 8949-2008.

This document defines the terms and definitions for polyurethane artificial leather, specifies its classification and requirements, inspection rules, marking, packaging, transportation and storage, and describes the corresponding test methods. This document applies to the production, inspection, and sale of polyurethane artificial leather.

4 Classification

See Table 1 for classification by backing fabric variety.

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. 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 mm.

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.
