1、Designation: F1561 03 (Reapproved 2014)Standard Performance Requirements forPlastic Chairs for Outdoor Use1This standard is issued under the fixed designation F1561; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last

2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 These requirements establish nationally recognized per-formance requirements for Class A (residential) and Class B(nonresid

3、ential) plastic chairs intended for outdoor use.1.2 These requirements do not address conditions that affectthe performance of the chair beyond the manufacturing site.1.3 These requirements are not applicable to chaises, mul-tipositional chairs, upholstered chairs, or other types of furni-ture.1.4 T

4、hese requirements cover the physical performance ofproduct regarding the aspects of outdoor weathering, impact,static load, and rear leg testing.1.5 Products may be manufactured from recycled plastics aslong as the performance requirements are met.1.6 The values stated in inch-pound units are to be

5、regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.7 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the

6、user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
