4.1.4 Dimensions—Outside diameter, mini mum or average wall thickness (in inches, not gage number), and length.
4.1.5 Fabrication Operwions:
4.1 .5. 1 cold Bending or ‘oiIing.
4.1.5.2 Packing.
4.1.5.3 Rolling or Expanding into Tube Sheets.
4.1.5.4 Welding or Brazing—Process to be employed.
4. 1 .5.5 Hydrostatic Test or Nondestructive Electric Thst—Specify type of test (6.5).
4.1.5.6 Pressure Requirements—If other than required by 6.5.
4.1.5.7 Ends—Plain ends cut and dehurred will be furnished.
4. 1.6 Supplemen Wry Requirements—S Late nature and details.
4.1.7 certification—Certification is required (SectiOn 15).
4.1.8 Samples for Product (Check) Analysis— Whether samples for product (check) analysis shall be furnished.
4.1.9 Purchaser Inspection—If purchaser wishes to witness tests or inspection of material at place of manufacture, the purchase order must so state indicating which tests or inspections are to be witnessed (Section 13).
5. Chemical Composition
5.1 The material shall conform to the composition limits specified in Table I.
5.2 If a product (check) analysis is performed by the purchaser, the material shall conform to the product (check) analysis per Specification B 880.
6. Mechanical Properties and Other Requirements
6.1 Mechanical Properties—The material shall conform to the mechanical properties specified in Table 3.
6.2 Hardness—When annealed ends are specified for tubing in the stress-relieved condition (see Table 3), the hardness of the ends after annealing shall not exceed the values specified in Table 3.
6.3 Flare—A flare test shall be made on one end of 1 % of the number of finished tube lengths from each lot. For less than 100 tubes in a lot, a flare test shall be made on one end of one tube length in the lot.
11. 1 Tension Test:
11.1.1 Tension test specimens shall be taken from material in the final condition (temper) and tested in the direction of fabrication.
11.1.2 Whenever possible. all tubes shall be tested in full tubular size. When testing in full tubular size is not possible. longitudinal strip specimens, or the largest possible round specimen, shall be used. In the event of disagreement when full tubular testing is not possible, a longitudinal strip specimen with reduced gage length as contained in Test Methods E 8 shall be used.
11.1.3 In the case of stress-relieved tubes furnished with annealed ends, the tension test shall he made on the stress-relieved tubes prior to annealing the ends.
11.2 Hardness Test:
11.2.1 Stress-Relieved Tubing with Annealed Ends— The hardness test may be made on the inside of the tube near the end or on a specimen cut from the end, at the option of the manufacturer. The test shall be made on the inside of the specimen.
12. Test Methods
12.1 The chemical composition, mechanical, and other properties of the material as enumerated in this specification shall be determined, in case of disagreement, in accordance with the following methods:
Test ASTM Designation
Chemical Analysis E 76, E 1473.
