Performance Characteristics

These tests were performed under strict laboratory controlled conditions and may vary depending on type of wire and terminal combinations, wire stripping methods, and maintenance or

proper gauging and calibration of manufacturer’s recommended tooling.

CHART 9072

Corrosion (Salt Spray) Test

48 hours, 5% NACL Fog

Note: Specification Maximum: Voltage drop of equivalent wire length, plus specification

allowance.

Salt Spray (Corrosion Test)

•

The purpose of this test, in which terminal samples are subjected to a file mist of

5% salt solution for a specific time (48 hours), is to provide an accelerated

laboratory conducted corrosion test.

•

The curves shown on chart 9072 plot the final voltage drops (i.e., after subjecting

the samples to salt spray), as called for in specification AS7928. For a terminal to

meet or exceed requirements, its voltage drop readings after test must fall below

limits shown in the upper curve (final). All Hollingsworth Military approved

terminals exceed AS7928 Salt Spray (Corrosion) Test requirements.

CHART 9073

Vibration Test 10-55 C.P.S.

36 hours

Note: Specification Maximum: Voltage drop of equivalent wire length, plus specification

allowance.

Vibration Test

•

The purpose of this test is to determine the detrimental effect of vibration on the

terminal. Terminals are attached to each end of a suitable length of wire. The test

terminals are mounted in a specially built vibration machine, confirming to the

requirements as set out in paragraph 4.7.7 of specifications AS7928.

•

The test terminals are subjected to vibrations of 10 through 55 cps. for a period of

18 hours in one plane and a further 18 hours in a plane normal to the first; a total

test period of 36 hours aand are subjected to voltage drop tests before and after

vibration.

•

The curves shown on chart 9073 plot voltage drops (i.e., after subjecting the

samples to the vibration test). For a terminal to meet or exceed requirements, its

voltage drop readings after test must fall below the limits shown in the upper curve

9final). All Hollingsworth Military approved terminals exceed AS7928 Vibrations

Tests.

Tensile Strength Test

•

The purpose of this test is to ensure secureness of the crimped terminal. The test is carried out as indicated under paragraph 4.7.8 of specifications AS7928.

•

After crimping the terminal to a suitable length of wire, it is placed in a standard tensile testing machine and sufficient force is applied to pull the wire out of the

terminal or break the wire, or the terminal.

•

The lower curve on charts 9074 and 9075 plots the minimum pull out force expected for the various wire sizes crimped. The upper curve plots average pull out forces measured in

actual tests on numerous samples. All Hollingsworth Military approved terminals exceed AS7928 Tensile Strength requirements.
