Die Annotation des Normtextes ASTM D4771-19 :

This performance specification covers the performance requirements for knitted upholstery fabrics as used in the manufacture of new indoor furniture for general domestic use. These requirements apply to both the wale and course directions for those factors where each fabric direction is pertinent. This performance specification is not applicable to fabrics used in contract, porch, deck, or lawn furniture; nor for woven fabrics, bonded or laminated fabrics, or surface-coated fabrics (such as vinyls and urethanes). The fabric shall be tested for its resistance to yarn slippage, dimensional change, and colorfastness to water, solvent, crocking, burnt gas fumes, light, and ozone. After the fabric has been tested, it shall be evaluated for any change in hand, character, or appearance. The fabric shall be evaluated for cracking or peeling of the back coating to check the coating durability. The fabric flammability shall also be tested. All upholstery fabrics shall be evaluated for cigarette ignition resistance.
