3. REQUIREMENTS
3.1 First article. When specified (see 6.2), a sample shall be subjected to first article inspection in
accordance with 4.2.
3.2 Material. The base material shall be a synthetic rubber or plastic cellular compound processed to
meet all of the requirements of this specification. The use of reclaimed or natural rubber is prohibited.
3.3 Construction.
3.3.1 Form. The material shall have a polymerized or vulcanized homogeneous (free from foreign
material) cellular structure with a porous surface and open cells. The cells shall be interconnecting and uniform in
size. The form of the material shall be in sheets or in assembled or molded shapes, as specified (see 6.2). Solid
fillers, flame retardant chemicals, and other additives used to achieve appropriate performance standards as
specified in this specification shall not be deemed "foreign" material within the meaning of this section.
3.3.2 Finish. When a finish, such as a cloth scrim, is required to improve the strength, tear resistance,
and so forth on the finished shape, it shall be as specified (see 6.2).
3.3.3 Manufacturing requirements. Cellular material for mattresses and cushions may be molded in one
piece or may be assembled by laminating to achieve thickness, and by butting to achieve width or length.
Assembled items shall be cemented together. Incidental defects in the cellular material which occur in standard
manufacturing practices and assembly will be allowed if they are corrected as indicated and the resulting product
conforms to this specification.
(a) Tears occurring during removal from mold shall be cemented together.
