Tere are some common leather durability ratings:

1. ISO 11640: This standard specifies the test methods and evaluation criteria for the abrasion resistance of leather colors. It defines 4 levels, from lowest to highest: Level 1, Level 2, Level 3, and Level 4.

2. ASTM D7255: This standard is also used to test the friction resistance of leather color. It defines 5 levels, from lowest to highest: Level 1, Level 2, Level 3, Level 4, and Level 5.

3. ISO 105-X12: This standard is used to test the light fastness of leather color. It defines 8 levels, from lowest to highest: Level 1, Level 2, Level 3, Level 4, Level 5, Level 6, Level 7, and Level 8.

4. ISO 105-B02: This standard is used to test the water resistance of leather color. It defines 5 levels, from lowest to highest: Level 1, Level 2, Level 3, Level 4, and Level 5.

5. ISO 11641: This standard is used to test the perspiration resistance of leather. It defines 4 levels, from lowest to highest: Level 1, Level 2, Level 3, and Level 4.

These standards apply not only to leather, but also to other fibers and materials. When selecting a test method, it should be selected according to the specific performance requirements and standard requirements of the required test.
