ASTM F1858-98(2014) - 1.9.2014
 
Significance and Use

4.1 Tests and criteria as outlined determine the overall usability and stability of chairs in an environment simulating the conditions of use.

4.2 Tests simulate two types of surfaces:

4.2.1 Smooth surfaces, such as linoleum, wet pool decks, etc. The glass testing base (see Fig. 5) is used to simulate this surface.

Note 1: (A) Poly(methoyl methoacrylate) sheet, 0.25 ± 0.03-in. (6 ± 0.1-mm) thickness; and (B) AC exterior glue fir plywood sheet, 0.75 ± 0.08 in. (19 ± 0.2 mm) or greater in thickness.

Note 2: (A) and (B) shall be roughly the same dimensions, 48 in. (1219 mm) or greater.

 
1. Scope

1.1 These performance requirements cover nationally recognized performance requirements for multipositional plastic chairs, with adjustable backs or reclining mechanisms, intended for outdoor use.

1.2 These performance requirements are not applicable to chaise lounges, 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 Manufactured from Recycled Plastics—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.
