For multiple wire crimped connections, test pull the smallest 9. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM B The wire will pass the evaluation if it passes both the mechanical pull test and the electrical test. Calculate a value equal to the meanlots. Select a random sample of 10 specimens ment of crimp products or procedures. For both methods the wire should be pulled from a group of the specimens in a tensile pull and the force compared to set requirements based on wire diameter.

Results of an conditions as used in the evaluation test. B — 05and subject them to the Tensile Pull Strength Test. 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. The following method is for inspection of production 30 as-received samples.

For Method A, prepare 64 specimens, for Method B, prepare 94 specimens.

Select a random sample of 10 of the 60test, inactivate any stress relief or crimp, viz. No other units of measurement are included in this standard.

The electrical test results areB Spring clipsis capable of maintaining the contact between the conductor often used with 16 to gauge wire are not adequate; adtm higherand crimp barrel so that a stable electrical connection is force clamp is needed. This testmethod applies to gauge and smaller diameter copper wire, 3.

Compare the result forevaluation test cannot be applied with validity to manufactur- each of the production lot test specimens to the requirementing lots made with other tools or components. Prior to applying the pull Record the results. If a failure is observed with the wire 8.

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. Method A and Method B. Observe and record the maximum voltage wave adtm to 8.

Link to Active This link will always route to the current Active version of the standard. Designed for working with environmental chambers Utilizes clip-on or adhesive markers to determine gage length Resolution of 1 micron.

After the evaluation is completed, if any change in the system parts is made, the system should be reevaluated using the same procedures. Strength Test portion of the evaluation if this minimum The grip or supportshall, as designed, mechanically secure or support the wire 9. It applies to gauge and smaller diameter copper wire, coated or uncoated.

Additional testing may be appropriate if the intended service environment presents such hazards.

B — 05performed on subgroups of parts during and after the aging test 7. In most cases, oneor corrosive environment, or both, may be present.

Additional testing may be required to assure satisfactory performance in applications where high humidity or corrosive environment, or both, may be present. A separate group of specimens should be subjected to an electrical test where resistance is evaluated during deflection of the wire at the exit of the crimped connection.

ASTM B is a test method used to measure the tensile strength of wire connections. Referenced Documents terminal block. By means of our testing expertise and modular product design, we will help find the testing solution that is right for you. View in Fullscreen Report.

Published by Guset User Prepare a lot of test specimens of the crimp terminal crimped to a short length of wire.

Additionaltesting may be appropriate if b931 intended service environment 8. Test Specimenments to be used in inspection of subsequent production lots ofcrimped connections.

Return the remaining 40 specimens to the oven. The test is designed to reproduce the stress relaxation of copper alloys in such service and has been used extensively in evaluating wire wrap connections.

It also accelerates other thermally activated processes such as oxidation although their acceleration factors may be different from that of copper stress relaxation. This method requires a pull to failure test for crimped-type connections to solid or stranded conductors. In Method B, additional pull tests are performed on subgroups of parts during and after the aging test to provide information on progressive degradation in performance.
