ISO 8092-5:2021 Road vehicles — Connections for on-board electrical wiring harnesses — Part 5: Test methods and general performance requirements for wiring harness connector operation.
4.3.3 Test procedure
The application of this test shall he agreed between customer and supplier.
a) Prepare a sound level meter as per IEC 61672-1, paragraph 2, to be able to measure sound of frequency range 20 Hz to 20 kHz, frequency characteristic A, and time weighting F. Calibrate the sound level meter before measurement.
b) Prepare a measurement room where the ambient sound is 50 dB maximum. Place sound absorbing material such as a carpet under the connectors to be mated and sound level meter.
c) Hold the parts of the connector to be mated at a position 600 mm to 660 mm from the sound level meter at a height of 600 mm to 1 000 mm from the sound absorbing material, facing them toward the sound level meter as shown in Figure.5. Mate the connector 4 times at the different insertion angles of approximately 30°, horizontal, approximately 30° opposite from the first time, and the same as the first time as shown in Figure 6.
d) When mating connectors, hold connectors with cotton work gloves (to match worst-case assembly conditions). Assure fingertips do not touch the connector lock. Measure each of the 5 samples (measurement direction and quantity may be changed by agreement between customer and supplier).
e) Record the generated sound levels.
f) Analyse measurement results using a 1/3 octave analyser.
a) The peak sound level: at> 5 kHz frequency shall he 60 dB minimum.
b) Overall value (L0J shall be 70 dB minimum.
4.4 Locking latch releases force measurement and classification
4.4.1 Sample preparation Prepare samples as follows.
a) Prepare 5 samples of male housing and female housing without terminal.
b) Bore a hole on the lock projection-side housing to attach a tension jig. However, lilt is difficult to bore a hole for structural reason, It is allowed to attach the terminal with which a cable is wired to the housing and pull the cable.
c) In the case of pulling the cable, insert the terminal with which the cable is wired on the pulling side only in order to prevent the influence of terminal unmating force (or mating force).
4.4.2 Test procedure Prepare samples as follows.
a) Mate one set of male and female housing and fix the lock lever-side housing securely using a fixing jig. When fixing the housing, take care not to allow the housing to be deformed during measurement.
b) Securely fix the other half of the mated housings, and measure the force required to have zero locking overlap.
c) If it is difficult to check the locking overlap, apply the force to the lock lever while pulling the lock projection-side housing as shown in Figure Z and measure the force required to release the locking.
d) Perform the measurement for each of the 5 mated housing sets and record the unlock load (Fh).ISO 8092-5 pdf download.
