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 (Fig. 2) is used to simulate this surface.
Rough surfaces such as wooden decks, outdoor grassed areas, etc. The plywood testing base (Fig. 3) is used to simulate this surface.
Note—A = poly(methyl methacrylate) sheet (see standard specifications); B = AC exterior glue fir plywood (see standard specifications); C = polypropylene microfoam sheet (see standard specifications); D = glass/tempered (see standard specifications).FIG. 2 Glass Testing Base

1.1 These requirements establish nationally recognized performance requirements for Class A (residential) and Class B (nonresidential) plastic chairs intended for outdoor use.
1.2 These requirements do not address conditions that affect the performance of the chair beyond the manufacturing site.
1.3 These requirements are not applicable to chaises, multipositional chairs, upholstered chairs, or other types of furniture.
1.4 These requirements cover the physical performance of product regarding the aspects of outdoor weathering, impact, static load, and rear leg testing.
1.5 Products may be manufactured from recycled plastics as long as the performance requirements are met.
1.6 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.
1.7 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.
