ASTM F1566-99(2004)

Standard Test Methods for Evaluation of Innersprings and Boxsprings

SIGNIFICANCE AND USE
Four separate test methods are outlined for use in evaluation of mattress innerspring or boxspring units, or both.
These test methods include measurements of firmness, firmness retention, durability, effect of impact, etc.
One or more of the test methods shall be used separately or in combination to provide for appropriate evaluations.
SCOPE
1.1 These test methods cover nationally recognized methods for testing mattress innersprings and boxsprings to ensure uniformity of results.
1.2 These test methods are applicable to un-upholstered innersprings and boxsprings only and are not applicable to finished upholstered mattresses or boxsprings. Any conclusions covering such items are outside the scope of these test methods.
1.3 The durability test (Section 7), impact test (Section 8) and firmness retention test (Section 9) require the use of an upholstered innerspring or boxspring, or both. A standardized upholstery is specified in each case.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 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.
