ANSI SCTE 73-2018 pdf free download – Test Method for Insertion Force of Connector to Drop Cable Interface.
4.6 Set the full-scale limit of the test system to a value appropriate for the connector/cable combination under test. For most tests an upper full-scale limit of50 lbs should be sufficient.
4.7 Place the cable sample(s) to be tested into the center hole of the Insertion Force Test Fixture with the prepared end pointing up. Ensure that the braid of the cable sampleis folded back properly. Place a properly prepared”standard test cable””sample intothe Insertion Force Test Fixture.
4.8Securely attach the connector(s) to be tested onto the F-81 barrel, which is held in the cross-head grips.
4.9 Lower the cross-head of the tensile test fixture，slowly，until the connector is properly aligned with the cable sample.
Notes:
1. lt may be desirable to allow the connector to just begin to slip under thebraid/jacket of the cable itself.
2. The angle of the connector-to-cable insertion alignment is critical to this measuremeni.
4.10 Start the tensile test fixture chart recorder, then initiate movement of the test fixture cross-head and start recording data.
4.11 When the maximum limit(s) of either“excursion””or”force”are achieved,the tensile test fixture should be stopped either automatically or manually.
4.12 Repeat steps 4.7 to 4.11 for each of the five“standard test cable”samples per connector type to be tested.
5.0Procedure 2:”Standard Connector”Vs Various Cable Types
5.1 Use appropriate wedge shape grips on both the “base” and“cross-head”of the tensile test apparatus.The wedge grip on the base should be fitted with“flatgripper”plates while the cross-head wedge grip should have”V-grooved gripper”plates.
5.2 Place a drop barrel (F-81) connector in the V-groove of the cross-head grips.
5.3 Measure the“ferrule”length of the connector(s) to be tested. The tensile test apparatus“maximum excursion limit”should be set to this length. This willprevent false readings caused by the cable’s bottoming” out improperly.
5.4 Place the “Insertion Force Test Fixture”into the base grip, securely.5.5Set the cross-head speed of the tensile test fixture to 0.5″” per minute.
5.6 Set the full-scale limit of the test system to a value appropriate for the connector/cable combination under test. For most tests an upper full-scale limit of50 lbs should be sufficient.
5.7 Place the cable sample(s) to be tested into the center hole of the Insertion Force Test Fixture with the prepared end pointing up.Ensure that the braid of the cable sample is folded back properly. Place a properly prepared test cable sample into theInsertion Force Test Fixture.
5.8Securely attach the “standard connector(s)” to be tested onto the F-81 barrel, which is held in the cross-head grips.
5.9 Lower the cross-head of the tensile test fixture，slowly，until the connector is properly aligned with the cable sample.
Notes:
1. lt may be desirable to allow the connector to just begin to slip under thebraidljacket of the cable itself.
2. The angle of the connector-to-cable insertion alignment is critical to this measuremeni.
5.10 Start the tensile test fixture chart recorder, then initiate movement of the test fixture cross-head and start recording data.
5.11 When the maximum limit(s) of either“excursion”or “force”are achieved，the tensile test fixture should be stopped either automatically or manually.
5.12 Repeat steps 5.7 to 5.11 for each of the five “standard connectors” per cable type to be tested.ANSI SCTE 73 pdf download.
