Self-Locking Torque (3 Cycles) as Received
a. Insert shall be installed into test block shown in Figure 1 by the method given in AS3507.
b. The self-locking torque shall be measured and recorded and shall not be less than values specified in Table 3,Column 2a, 2b, and 2c (cycles 1 to 3) nor greater than the values specified in Table 3, Column 3. On the 15t cycle only, 20% of parts tested may exceed the maximum locking torque (Table 3, Column 3) by 10% of the stated value for the insert size being tested.
c. Bolt shall be seated on spacer located on top of the test block and tightened to the seating torque specified in Table 3, Column 5 (cycles 2 and 3).
d. Unscrew the bolt and measure and record the breakaway torque for each cycle. Torque values shall not be less than those specified in Table 3, Column 2a, 2b, and 2c (cycles 1 to 3).
Each insert shall be identification marked as specified by the standard part drawing. Unless otherwise specified, the markings may be formed by stamping or machining, raised or depressed 0.015 maximum. The manufacturer’s identification mark shall be defined on the manufacturer’s drawing.
The supplier of parts shall provide all samples and shall be responsible for performing all required tests. The purchaser reserves the right to perform such confirmatory testing as deemed necessary to assure that the parts conform to the requirements of this specification.
The manufacturer’s system for insert production shall be based on preventing product defects, rather than detecting the defects at final inspection and then requiring corrective action to be invoked. An effective manufacturing in-process control system shall be established, subject to the approval of the purchaser, and used during production of inserts.
Qualification tests shall be performed on inserts selected from the first lot of each size produced by a manufacturer and shall be repeated whenever a significant change is made in the manufacturing process. The qualification tests shall consist of those tests and inspections defined in Table 4.SAE AS 3506B pdf free download.
