Historical (view previous versions of standard)
Significance and Use
Tests and criteria as outlined determine the overall usability and stability of chairs in an environment simulating the conditions of use.
Tests simulate two types of surfaces:
Smooth surfaces such as linoleum, wet pool decks, etc. The glass testing base (see Fig. 5) is used to simulate this surface.
Rough surfaces such as wooden decks, outdoor natural surfaces, etc. The plywood testing base (see Fig. 6) is used to simulate this surface.
A = poly(methyl methacrylate) 0.25 ± 0.03 in. (6 ± 0.1 mm) thickness,
B = AC exterior glue fir plywood 0.75 ± 0.1 in. (19 ± 2 mm) or greater thickness,
C = polypropylene microfoam 0.7± 0.01 lb/ft3 (11 ± 0.2 kg/m3) density and 0.13 ± 0.01 in. (3 ± 0.03 mm) thickness, and
D = glass/tempered 0.38 ± 0.04 in. (10 ± 0.1 mm) thickness.
Note 2—A, B,C, and D are sheets roughly 48 in. (1219 mm) on a side or greater to accommodate the length of the chaise lounge.FIG. 5 Glass Testing Base

1.1 These performance requirements establish nationally recognized performance requirements for Class A (residential) and Class B (nonresidential) plastic chaise lounges, with or without moving arms, with adjustable backs, intended for outdoor use.
1.2 The performance requirements are not applicable to upholstered chairs, or other types of furniture.
1.3 These performance requirements cover the performance of the product regarding aspects of outdoor weathering, impact, static load for seat and back, and arm testing.
1.4 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 standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
