Standard Performance Requirements for Multipositional Plastic Chairs with Adjustable Backs or Reclining Mechanisms for Outdoor Use

Importancia y uso:

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.

FIG. 5 Glass Testing Base

Note 1: (A) Poly(methyl methacrylate) sheet, 0.25 ± 0.03-in. (6 ± 0.1-mm) thickness; (B) AC exterior glue fir plywood sheet, 0.75 ± 0.08 in. (19 ± 0.2 mm) or greater in thickness; (C) polypropylene microfoam sheet; 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 sheet, 0.38 ± 0.04-in. (10 ± 0.1-mm) thickness.

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

4.2.2 Rough surfaces, such as wooden decks, outdoor natural surfaces, etc. the plywood testing base (see Fig. 6) is used to simulate this surface.

FIG. 6 Plywood Testing Base

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.
