3.12 Workmanship. The shields, including all parts and accessories, shall

be constructed and finished in a thoroughly workmanlike manner. Particular

attention shall be given to strength of welds, neatness and thoroughness of

painting, riveting, machine-screw assemblies, molding, forming, fit, function,

et cetera. Parts, assemblies and end items shall be free of defects such as,

but not limited to, burrs, cracks or crazing, fatigue, loose components, and

rough or sharp edges.

3.12.1 Dimensional tolerances. Dimensions and tolerances not specified

sions and tolerances may affect the interchangeability, operation, or perform-

ance of the shield, they shall be held or limited accordingly.

3.12.2 Class 1 shields shall be fabricated by drawing or bending and welding,

except where ease of servicing of the shields requires that a removable panel

construction be used or where the applicable stresses dictate the use of

strong aluminum alloy that does not provide a good weld; for such parts,

riveting or bolting may be used.

3.12.3 Molding, forming, pressing, et cetera, of class 2 shields shall be

accomplished with the use of accurate molds, presses, and forms. Shields

shall be fabricated for ease of installation and removal and to provide a

press fit in the required orifice.

items such as lock washers, lock nuts, safety wiring, cotter pins, epoxy, et

cetera, shall be used as necessary.

3.12.5 Riveting. Riveting operations shall be performed to insure that the

rivets are tight and satisfactorily headed.

3.12.6 Cleaning. The shields shall be thoroughly cleaned of loose, spattered,

or excess weld, metal chips, or other foreign material after final assembly.

Burrs and sharp edges, as well as resin flash that may crumble, shall be

removed.
