Studies show that assembly plant workers depend on audible feedback to indicate full seating of electrical connectors. This test measures the level of sound generated when two connectors are mated. Connectors are mated by hand for this test, rather than being clamped into a fixture which could dampen or amplify the sound. This test is applicable only for connectors intended to produce a sound on connection. 4.3.2 Sample preparation Prepare measurement samples as described in 4.11. 4.3.3 Test procedure The application of this test shall be 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.ISO 8092-5 pdf download.
