21、 General description The specimen is immersed in water for a specified period of time. 2 Apparatus The apparatus consists of the following elements. 2.1 Containers A boro-silicate glass or stainless steel vessel of suitable volume for the water shall be used. Vessels shall be of sufficient size and
22、capacity to permit the specimen to be appropriately immersed in water without violating other physical constraints (e.g.the minimum cable bend radius). 2.2 Water Distilled water. 2.3 Heat source A suitable heat source capable of achieving and maintaining the specified temperature within 2 C of there
23、quired setting. 2.4 Oven A suitable oven to dry the specimen during repeated immersion testing. 3 Procedure The preparation of the specimen shall be in accordance with the relevant specification. Perform any pre-test measurements specified in the relevant specification. Unless otherwise specified, t
24、he specimen shall be subjected to the test in a non-operational mode. 3.1 Precondition the specimen and the water as specified in the relevant specification. 3.2 Prepare a vessel with sufficient water such that the specimen can be adequately immersed. The quantity of water shall be sufficient such t
25、hat the device under test is1cm to5cm below the surface of the water. 3.3 Immerse the specimen for the specified period while maintaining the water temperature. The specimen shall be immersed during the test. 3.4 At the end of the specified period, remove the specimen from the bath. 3.5 The surplus
26、water shall be wiped off and the specimen shall be allowed to dry at room temperature for24h without controlling its humidity following the removal from the immersion bath. 3.6 When the repeated immersion test is carried out, the surplus water shall be wiped off and the specimen placed in the oven t
27、o dry for2h at40 C. Before the next immersion, the specimen shall be allowed to stabilise at room temperature for2h. This procedure shall be repeated following subsequent immersions. 3.7 Upon completion of the test, the specimen(s) shall be examined and all necessary observations recorded as specifi
28、ed in the relevant specification. Special attention shall be paid to swelling of materials, loss of adhesive bonding between bonded surfaces, corrosion of materials, softening of materials, degradation of optical characteristics, etc.EN61300-2-45:1999 4 BSI 02-2000 4 Severity The severity consists o
29、f a combination of the following: water temperature, period of immersion, number of cycles of immersion and depth of immersion. The severity shall be specified in the relevant specification. The following severities, which are not mandatory, may be specified for this procedure. 5 Details to be speci
30、fied The following details, as applicable, shall be specified in the relevant specification: specimen optically functioning or non-functioning; pre-conditioning procedure; water temperature; depth of immersion; immersion period; recovery procedure; initial examination and measurements and performanc
31、e requirements; final examination and measurements and performance requirements; number of immersion cycles; deviations from test procedure; additional pass/fail criteria.
