This testmethod applies to gauge and smaller diameter copper wire, 3. Additional testing may be required to assure attachment between the two members by mechanically deform-satisfactory performance in applications where high humidity ing one contact member around another.

In most cases, oneor corrosive environment, or both, may be present. No other units of measurement are included in this terminal that is deformed in the crimping operation. The other end of the terminalregulatory 9b13 prior to use. Referenced Documents terminal block. The electrical test results areB A test lot passes the evaluation if it passes both the mechanical pull test Current edition approved Nov.
Originally and the electrical test. In Method 9b13, additional pull tests areapproved in Last previous edition approved in as B — 00e1. B — 05performed on subgroups of parts during and after the aging test 7. Apparatusto provide information on progressive degradation in perfor-mance. An oscilloscope with aconductors. A reliable crimped connection is one that apart on an insulating base has proved suitable. Spring clipsis capable of maintaining the contact between the conductor often used with 16 to gauge wire are not adequate; a higherand crimp barrel so that a stable electrical connection is force clamp is needed.
The oventhe system should be reevaluated using the same procedures. Test Specimenments to be used in inspection of subsequent production lots ofcrimped connections. An example of such an acceptance 8. For Test Method A, prepare 64 specimens, for 5.
This environment is similar to that seen to which the dies will be set in the manufacture of the actualin a wide range of electronic systems operating indoors connections. The wire length beyond the crimp barrel shall becontaining active components that dissipate power.
The test is mm 8 in. In each test method, the 64 or 94designed to reproduce the stress relaxation of copper alloys in specimens provide four extra specimens beyond those actuallysuch service and has been used extensively in evaluating wire required for testing, the remaining four can be used in test setwrap connections.
It also accelerates other thermally activated up or retained as examples of the manufactured test specimensprocesses such as oxidation although their acceleration factors since the testing is destructive. Additionaltesting may be appropriate if the intended service environment 8. The strain relief shall be disabled prior to testing the 8.
Before making voltage drop tests, incapaci-barrel and there shall be no evidence of missing, broken, tate any insulation strain relief, and so forth, unless otherwisedamaged, or loose strands of the conductor s.

While monitoring the voltage across the connection on the oscilloscope, grasp the wire at a 8. Observe and record the maximum voltage wave peak to 8. If a failure is observed with the wire 8.

Position them in the 9. For multiple wire crimped connections, test pull the smallest 9. Prior to applying the pull Record the results.
Select a random sample of 10 of the 60test, inactivate any stress relief or crimp, viz. Select a random sample of 10 specimens 3. B — 05and subject them to the Tensile Pull Strength Test. Record the peak-to-peak for 16, 18, 20, and gauge wire crimps or results. Return the remaining 40 specimens to the oven.
Observe whether the strength declines with aging. Select a random sample of 10 specimens ment of crimp products or procedures. Return ashm remaining 30 v913 to the oven.
