3.9.3.1 Thickness. The thickness tolerances of cold rolled nickel- copper-aluminum alloy sheet and strip, all conditions, shall conform to the requirements specified in table XII. The tolerances on thickness of hot rolled nickel-copper-aluminum alloy plate, all conditions, shall conform to the requirements specified in table XIII.

3.9.3.2 Width. The width of sheet and strip shall not vary from the ordered width by more than the amount specified in table XIV and those for plate shall be as specified in table XV.

3.9.3.3 Lengths.

3.9.3.3.1 Sheet. Unless otherwise specified (see 6.2), sheet shall be furnished in cut lengths. The permissible variation in length shall be plus

1/8

inch, minus nothing.

3.9.3.3.2 Strip. Unless nominal or stock lengths or cut lengths are specified, strip, in conditions other than age hardened, shall be furnished in coil in thicknesses up through 0.125 inch and in random straight lengths in thicknesses over 0.125 inch. Unless otherwise specified (see 6.2), age hardened strip shall be furnished in straightened (cut) lengths only.

A) The length of cut length strip shall not vary under or over the

ordered length by more than 1/8

inch.

B) Nominal or stock lengths. The length of strip up to 12 inches wide, ordered as nominal or stock lengths, shall not vary from the ordered

nominal or stock length by more than � inch, except for the

permissible amounts of short lengths specified in table XVII. The

maximum percentage by weight of short lengths, and the required

percentage by weight of ordered stock lengths, in any shipment shall

be as specified in table XVII.

3.9.3.3.3 Plate. The permissible variations in length for plate shall be as specified in table XVI. The permissible variations in diameter for circular plate shall be as specified in table XVIII.
