located within the area of the rail which is designated as being safe for drilling in accordance with the chassis manufacturer's body builder's layouts. Attachments shall not interfere with nor obstruct existing chassis components.

3.11.3 Breaker strips. A hardwood or dense southern yellow pine breaker strip not less than 1.063 inches finished thickness shall be installed between longitudinal sills and vehicle chassis frame. Breaker strips shall have a taper of not less than 0.5 inch in 16 to 18 inches at the forward end.

* 3.12 Welding. Adequate preparation of metal prior to welding of the tank shell, appurtenances, components and accessories shall be provided. Surface of parts to be welded shall be free of dust, scale, paint, grease, and other foreign matter. Stainless steel electrodes or filler rods used in the welding process shall be for use with the grade of stainless steel specified herein and according to the recommendations of the manufacturer or producer of the stainless steel electrodes or filler rods. When welding the cabinet support members to any stainless steel pads or saddles, the ferritic particles shall not penetrate through the pads or saddles. The body shall be free of the following:

(a) Slug or plug welding

(b) Undersize of fillet welds, overlaps, inadequate fusion and penetration and

undercutting of weldments (c) Unremoved slag and spatter (d) Cracks

(e) Spot, tack, or intermittent welds for strength.

Weld penetration shall be such as to provide transference of maximum design stress through the base metal juncture. Intermittent welding shall be permissible when in accordance with 3.12.1 and 3.12.2.

3.12.1 Workmanship specimens. Workmanship specimens shall be prepared by the manufacturer for the body and components to simulate all welding conditions. The specimens shall be cross-sectioned and etched. The specimens shall represent the minimum acceptable weld quality and cleaning procedure to be used in production. The specimens shall be prepared using the welding procedures to be employed in production. Specimens prepared to represent multiple pass welds shall be made in such a manner as to leave at least two inches of each layer of weld metal exposed. Upon submittal of these specimens by the contractor, the quality level and identification shall be subject to approval by the Government.

3.12.2 Welded members. All members to be joined by welding shall be brought into contact or close proximity before welding. For fillet, butt and flare groove welds; including those for the heads, baffles and shell; the gap between members before welding shall be such as
