Abrasion
This symbol refers to abrasion which tests how well a fabric withstands rubbing against another fabric. When a fabric exceeds 30,000 Wyzenbeek double rubs, this symbol may be displayed in the specifications of a fabric. If the abrasion exceeds 15,000 double rubs, but is less than 30,000, a lower case "a" is used. Note that having more double rubs doesn't necessarily equal better performance.

Colorfastness to Light
Measures the materials degree of resistance to the fading effects of light. While there is no direct correlation between the test and actual use, it can give you confidence it won't fade unexpectedly fast.

Flammability
The measurement of a fabric's performance when it's exposed to specific sources of ignition. This covers tests like California Tech Bulletin 117-2013 Section 1 for upholstery, ASTM E84 for panels and NFPA 701 for drapery.

Wet & Dry Crocking
This test measures the transfer of dye from the surface of a dyed or printed fabric onto another surface by rubbing. This test answers the question: If you are wearing white pants, will color of the chair you sit on rub off on to your pants?

Physical Properties
Covers multiple tests that assess the overall durability of a fabric depending on the fabric construction. Breaking Strength (how much force does it take to pull it apart), Pilling (If rubbed, do fuzzy balls form?), Seam Slippage (when sewn together, how much force does it take to pull apart?) and Tear (how much force to rip the fabric).

Facts
This symbol recognizes fabrics that meet the multi-attribute sustainability standard NSF/ANSI 336 and are third party certified. Once a fabric is deemed Compliant, it can be designated as Facts Silver, Gold or Platinum by earning points based on eight sustainability attributes. The eight sustainability attributes measured are fiber sourcing, safety of materials, water conservation, water quality, energy, air quality, recycling practices and social accountability.
