UL 764:1998 pdf download FOLLOW-UP AND INSPECTION INSTRUCTIONS RECOGNIZED PROCESSED WIRE RECOGNIZED PROCESSED WIRE – RESPOOLED (ZKLU2, ZKLU8)
At each inspection, representative samples of Recognized Processed WireL8and/or Processed Wire-Respooled having simple terminations shall be subjectedto the tests described in Table Ll. For Recognized Processed Wire and/orProcessed Wire-Respooled having simple terminations attached,the ULRepresentative will verify that the processed wire size and construction iswithin the wire connector’s wire range.

1-Detailed examination per Descriptive Section2Conductor Secureness of Simple TerminalsI0Visual Examination of Simple Terminals-
Conductor Secureness Test
L9At each inspection， representative samples of Recognized Processed Wireand/or Processed Wire-Respooled having simple terminals attached by crimpingsoldering,or welding shall be subject to the ConductorSecureness Test.Please note that all terminals (Listed, Recognized, andUnlisted) are subjectto this test.
SAMPLES
I10 Eight samples shall be randomly selected from each lot for this test，Alot is considered to be all material of one AWG size in current production orstock, using the same type terminal or end treatment.
TEST METHOD
L11 All samples shall be checked for stray strands prior to test.Terminations (including those insulated by Recognized insulating tubing whichis heat-shrinkable, or secured in place by a heat-bonding process) are to besubjected to a conductor secureness (pull) test.The pull is to be appliedbetween the conductor and its terminal, Constructions using more than oneconductor in a crimp connection shall be tested by applying the pull betweenand the terminal.The pull shall be 8 1b. (3.6 kg) foreach conductorNo，20 AWG,and smaller conductors and 20 lb，(9.1 kg) for No，19 AWG andlarger size conductors.The pull shall be applied for l min.
BASIS OF ACCEPTABILITY
L12There shall be no separation of the connections or stray strands as aresult of the described pull.
PROCEDURE IN THE EVENT OF NONCONFORMANCE
L13If there are no nonconformances, accept the lot.In the case of onenonconformance，select sixteen additional samples from the lot forexamination. Accept the lot if no more nonconformances are observed.Rejectthe lot if two or more nonconformances are observed from all samples (firstThe rejected lot may be culled or reworked andand second) selected.resubmitted to the UL Representative for testing.
Visual Inspection
SAMPLES AND TEST METHOD
L14Representative samples of processed wire having simple terminals attachedare to be selected at random and are to be checked for stray strands.Selectfor examination of stray strands .four samples from each lot
BASIS OF ACCEPTABILITY
L15There shall be no stray strands resulting from the termination operation.
PROCEDURE IN THE EVENT OF NONCONFORMANCE
L16If there are no nonconformances, accept the lot.In the case of onenonconformance， select sixteen additional samples from the lot forRejectexamination， Accept the lot if no more nonconformances are observed.the lot if two or more nonconformances are observed from all samples(firstand second) selected. The rejected lot may be culled or reworked andresubmitted to the UL Representative for testing.
