Note 4 is not meant to be restrictive or to be used as, a basis for rejection but is intended to give general guidelines. Various production methods may be used to obtain these Snishes. When polished on one side only, it is permitted 10 rough rind the other side in order to obtain the necessary Aatness.
Finish, followed by a final light cokd-roll pass, generally on highly polished rolls Nore 5—Bsplanation of Strip Finishes: No. I—Appearance ofthis finish varies from dull gray matte fish to faityrfceive surface, depending lngely upon composition.
Finish for Plates Use of plates in this condition is generally confined to heat-resisting applications. Scale impairs corrosion resistance. Edges for Cold-Rolled Strip Rajan Steeve.

If any test specimen shows defective machining ordevelops flaws, it is permitted to discard the flawed specimenand substitute another specimen. If the results of any test lot are not in conformance withthe requirements of the applicable material specification,theproducer is permitted the option of retreating such lots.
Thematerial shall be accepted if the results of retests on retreatedmaterial are within the specified requirements. If any specimens selected to represent any heat fail tomeet any of the test requirements as specified in the applicablematerial specification, it is permitted to reheat treat the materialrepresented and resubmit it for testing. If the product analysis fails to conform to the specifiedlimits, analysis shall be made on a new sample. The results ofthis retest shall be within the specified requirements.
