126.96.36.199Pressure Requirements——If other thanrequired by 6.5.
188.8.131.52Ends——Plain ends cut and deburred willbe furnished.
4.1.6Supplementary Requirements——State natureand details.
4.1.7Certification—-Certification is required (Sec-tion 15).
4.1.8 Samples for Product (Check ) Analysis——Whether samples for product (check) analysis shall befurnished.
4.1.9 Purchaser Inrspection——If purchaser wishes towitness tests or inspection of material at place of manufac-ture,the purchase order must so state indicating whichtests or inspections are to be witnessed (Section 13).
5. Chemical Composition
5.1The material shall conform to the composition lim-its specified in Table 1.
5.2 lf a product (check) analysis is performed by thepurchaser, the material shall conform to the product (check)analysis per Specification B 880.
6. Mechanical Properties and Other Requirements6.1Mechanical Properties——The material shall con-form to the mechanical properties specified in Table 3.6.2Hardness——When annealed ends are specified fortubing in the stress-relieved condition (see Table 3), thehardness of the ends after annealing shall not exceed thevalues specified in Table 3.
6.3Flare——A flare test shall be made on one end ofl% of the number of finished tube lengths from each lot.For less than 100 tubes in a lot, a flare test shall be madeon one end of one tube length in the lot. In the case ofstress relieved tubing with annealed ends, the test shall bemade prior to,or subsequent to, annealing of the ends atthe option of the manufacturer.
6.3.1 The flare test shall consist of flaring a test specimen with an expanding tool having an included angle of 60° until the specified outside diameter has been increased by 30%. The flared specimen shall not exhibit cracking through the wall.
6.4 Grain Size—A transverse sample representing full- wall thickness of annealed alloys UNS N08120, UNS N08810 and UNS N08811 shall conform to an average grain size of ASTM No. 5 or coarser.
6.5 Hydrostatic or Nondestructive Electric Test —Each tube shall be subjected to either the hydrostatic test or the nondestructive electric test. The type of test to be used shall be at the option ofthe manufacturer, unless otherwise specified in the purchase order.
6.5.1 Hydrostatic Test:
184.108.40.206 Each tube with an outside diameter 1 ⁄ 8 in. (3.2 mm) and larger and tubes with wall thickness of0.015 in. (0.38 mm) and over shall be tested by the manufacturer
