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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Significance and Use
Fabrics intended for this end-use should meet all of the requirements listed in Table 1.
It should be recognized that fabrics can be produced utilizing an almost infinite number of combinations of construction variables (for example, type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanical finishes.) Additionally, fashion or aesthetics dictate that the ultimate consumer may find acceptable articles made from fabrics that do not conform to all of the requirements in Table 1.
Hence, no single performance specification can possibly apply to all the various fabrics that could be utilized for this end-use.
The uses and significance of particular properties and test method are discussed in the appropriate sections of the specified test methods.
1.1 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.
1.2 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).
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 The following safety hazards caveat pertains only to the test methods described in this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See Note 2.
