The Martindale test (also known as the rub test) is an internationally recognised measure for testing the durability of fabric for contract use. The higher the count is the more durable the fabric. Generally speaking,, a count of 10,000 or less is intended for decorative use, 30,000 or less is for domestic use, and anything above 30,000 is suitable for contract furniture (a.k.a. commercial use).
