BS 8479 is a standard test method developed by the British Standards Institution (BSI) for evaluating the resistance of textiles to wear and tear under specified test conditions. The test method involves subjecting a textile specimen to a series of mechanical actions including rubbing, flexing, and tumbling, and then evaluating the amount of abrasion or damage to the material.

The test conditions and equipment used in the BS 8479 method are designed to simulate the wearing and tearing effects that a textile material may be exposed to in real-world applications. The test is typically used to evaluate the quality and durability of textiles intended for use in clothing, upholstery, and other applications.

The BS 8479 test is one of several standardized methods used for evaluating the abrasion resistance of textiles. Other commonly used methods include the Martindale test, the Wyzenbeek test, and the Taber abrasion test.
