Method for Determining Breakage Allowances for Sheet Steel
This method is recommended for establishing breakage allowances for parts fabricated from cut lengths or blanks, or from coils processed directly into a progressive-die pressline, and is equitable to both the sheet producer and the fabricator. Breakage, for the purpose of this proposal, is defined as unrepairable parts, broken during forming and classed as scrap. Parts showing laminations, resulting from pipe, should be excluded provided they are separately identified. Broken parts which can be salvaged are not covered in this proposed method.
