Standard Specification for Tops, Furniture, Marine, Steel

ABSTRACT
This specification covers the construction of steel furniture tops for use where invoked by other marine furniture specifications. Tops shall be of the following types: type I - top on which the edge binder is flush with the top and the substrate material is steel; type II - top on which the edge binder projects above the upper surface of the top to act as a lee rail and the substrate material is steel; type III - top on which a lee rail is applied to the upper surface of the finished top, the top has a self edge securely bonded to the finished top, and the substrate material is a particle or mineral board core; and type IV - top is an insert panel and the edge binder is an integral part of the supporting furniture unit. Tops shall be of the following grades: grade 1 - substrate material and edge reinforcements for types I, II, and IV, and grade 2 - substrate material is a particle or mineral board core with a minimum density of 45 lb/ft3.
SCOPE
1.1 This specification covers the construction of steel furniture tops for use where invoked by other marine furniture specifications.  
1.2 This specification applies to tops for furniture case goods only such as chests of drawers, log desks with cabinets, and so forth.  
1.3 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.
