ASTM F1838-98(2004)e1
(Specification)Standard Performance Requirements for Child's Plastic Chairs for Outdoor Use
Standard Performance Requirements for Child's Plastic Chairs for Outdoor Use
SCOPE
1.1 These standard performance requirements establish nationally recognized performance requirements for Class A (residential) and Class B (nonresidential) child's plastic chairs intended for outdoor use.
1.2 These standard performance requirements are not applicable to chaises, multi-positional chairs, upholstered chairs, or other types of furniture.
1.3 These standard performance requirements cover the performance of product regarding aspects of outdoor weathering, impact, static load, and rear leg testing.
1.4 Products Manufactured from Recycled Plastics:
1.4.1 Products may be manufactured from recycled plastics as long as the performance requirements are met.
1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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.
