3. TECHNICAL REQUIREMENTS:
3.1 General:
3.1.1 Conformance: The vendor shall be responsible for furnishing products which conform to all requirements of the material specification. Sampling and testing for any requirements not covered herein or In the material specification shall be optional, unless otherwise specified by purchaser.
3.1.2 Lot: A lot shall be all product of (he same nominal size and shape, from the same ingot (heat), processed in the same manner, and presented for vendor’s inspection at one time. When processing includes heat treatment, product shall have been heat treated in one or more furnaces in the same load or sequentially heat treated in a series of furnaces (See 8.2) or a continuous furnace over not more than 48 hours providing there is no interruption in operations or change in furnace temperature setting(s), charge rate, or racking pattern.
3.1.3 Sampling and Testing: Shall be as follows:
3.1.3.1 CompositIon: Sampling and testing shall conform to 3.2.3.
3.1.3.2 Other Properties: Except as otherwise specified below, at least one test of each type shall be performed on specimens, located and oriented in accordance with 3.1-3.2.1 and 3.1.3.2.2, from a random sample from each lot.
3.1.3.2.1 Location of Specimens: When practical, tests shall be performed on full thickness specimens. When the poduct is too thick for testing its full thickness, the center of the specimen shall be located at the center of the thickness of the product for sizes less than or equal to 1.5 inches (38 mm) and at the mid-radius or quarter thickness for sizes greater than 1.5 inches (38 mm) or least difference between parallel sides. Short transverse specimens shall be located at the middle of the width of the product, Specimens from flash welded rings shall not include the weld or heat affected zone (See 8.5).
3.1.3.2.2 Orientation of Specimens: Shall be circumferential for flash welded rings and longitudinal for other products except that orientation may be transverse for product more than 1 inch (25 mm) thick and more than 8 inches (203 mm) wide.
3.2 Tests (In alphabetical order):
3.2.1 Bending:
I3.2.1.1 Bend tests shall be performed using the U-channel or free bend procedure In accordance with ASTM E 290. In case of dispute, the free bend procedure shall govern.
3.2.1.2 The axis of bend shall be parallel to the direction of rolling.
3.2.1.3 Width of specimens shall be 10 times the nominal thickness of the product or 1 inch (25 mm), whichever is greater, except that for free bend tests the width need not be greater than 1 inch (25 mm).
3.2.2 Coding: Tests shall be performed on two samples from each lot.
