TECHNICAL REQUIREMENTS 3.1 General 3.1.1 Omission from this specification of confirmatory tests of certain material properties or attributes controlled by the applicable specification for a product does not relieve the producer of
19、 responsibility for furnishing products which conform in all respects to the applicable material specification. 3.1.2 In event of conflict between requirements specified herein and requirements of a particular material specification, the following rules shall apply: 3.1.2.1 When requirements of the
20、material specification are more stringent, they shall take precedence. 3.1.2.2 When requirements of this AMS are more stringent, they shall take precedence except as noted in 3.1.2.3. 3.1.2.3 If any tests mentioned in 3.3 are not required by the material specification, they shall not be considered a
21、 requirement. 3.1.2.4 When instructions are issued by purchaser regarding quality assurance sampling procedures, such instructions shall take precedence over requirements of either this specification or the particular specification in which this specification is invoked. 3.1.3 Properties of the deli
22、vered product shall meet those of the specified (ordered) product. 3.1.3.1 For products, other than die and hand forgings, the applicable limits for mechanical properties, physical properties, cladding thickness, and ultrasonic discontinuity limits are those that apply to the specified (ordered) dim
23、ension. The applicable limits for die and hand forgings are defined by the thickness of the forging at the time of heat treatment. 3.1.3.2 When a specified (ordered) dimension or when a specified forging thickness at the time of heat treatment is expressed to more decimal places than published in th
24、e material specification, applicable limits are determined by rounding the specified (ordered) dimension to the same number of decimal places as the material specification in accordance with ASTM E29. 3.2 Responsibility for Tests The producer of the product shall supply all samples for producers tes
25、ts and shall be responsible for the performance of all specified tests. 3.3 Detail Requirements 3.3.1 Inspection Lot 3.3.1.1 Wrought Alloy Products Including Forged or Rolled Rings, but Excluding Die and Hand Forgings and Flash Welded Rings 3.3.1.1.1 Heat Treated Tempers An inspection lot shall be a
