TEST PROCEDURESUnless other
28、wise specified, the test procedures described in the current issue of ASTM A 370 Standard Methods and Definitions for Mechanical Testing of Steel Products shall be followed. However, in cases of conflict between the ASTM specifications and those described herein, this SAE specification shall take pr
29、ecedence.3.1 Test FrequencyThere are many factors which can affect the required frequency of these tests, including:a. Tube sizeb. Production run quantityc. Type of production equipmentd. Production methodse. End usef. MaterialTherefore, it shall be the responsibility of the manufacturer and user to
30、 establish the test type and test frequency that willproduce tubing which conforms to the SAE Standards as well as the needs and requirements of the user.4. TEST SPECIMENSIn accordance with ASTM A 370 Standard Methods and Definitions for Mechanical Testing of Steel Products, test specimens for mecha
31、nical tests shall be smooth on the ends and free from flaws. If any test specimen exhibits burrs, flaws or defective machining before testing, it may be discarded and another specimen may be selected. Test specimens shall be taken from tubing which has not been subjected to subsequent operations aft
32、er being manufactured to the applicable specification. All tests shall be conducted at room temperature.5. PERFORMANCE TESTSThe tests listed in this section are selected and performed based on agreement between the supplier and customer.5.1 Flattening TestTest specimens approximately 75 mm in length
33、 shall not crack or show any flaws when flattened between parallel plates to a distance equal to three times the wall thickness of the section under test. For welded tubing, the weld shall be placed at 90q from the direction of applied force. Superficial ruptures resulting from minor surface imperfe
34、ctions shall not be considered cause for rejection.SAE INTERNATIONAL J1677 DEC2016 Page 5 of 85.2 Reverse Flattening TestTest specimens shall be split longitudinally 90q on each side of the weld. The section containing the weld shall be opened and flattened with the weld at the point of maximum bend
35、. There shall be no evidence of cracks or metal flaking, or lack of weld penetration or overlaps resulting from flash control or flash removal in the weld.5.3 Bending TestIf a bend is required, the customer shall specify a suitable test method at the time of purchase.5.4 Expansion TestTest specimens
36、 shall be subjected to expansion over a hardened tapered plug having a slope of 0.1 to 1.0, until the outside diameter has been expanded 25% without evidence of cracking or flaws.5.5 Flaring Test5.5.1 SAE J533 37q and 45q Flares5.5.1.1 Double Flare - Method ATest sections having squared and deburred
37、 ends shall withstand being double flared at one end to the dimensions shown in SAE J533. The test section shall be held firmly and squarely in the die and the punch, while being forced down, and shall be guided parallel to the axis of the tubing. The flare shown in Figure 1 shall exhibit no evidenc
38、e of splitting or flaws.Figure 1 - 37q Double flared tubing -method A (Ref: SAE J533)5.5.1.2 Double Flare - Method BTest sections having squared and deburred ends shall withstand being single flared at one end to the dimensions shown in SAE J533. The test section shall be held firmly and squarely in
39、 the die and the punch, while being forced down and shall be guided parallel to the axis of the tubing. The flare shown in Figure 2 shall exhibit no evidence of splitting or flaws except that a separation of the outer lap joint shall be permissible providing it does not exceed 3.1 mm in length and i
40、s confined to the outer thickness only.Figure 2 - 37q Double flared double wall tubing -method B (Ref: SAE J533)5.5.1.3 Single FlareTest sections having squared and deburred ends shall withstand being single flared at one end to the dimensions shown in SAE J533.
