20、r immersion 1 General 1.1 Scope and object The purpose of this part of IEC 61300 is to establish the ability of a fibre optic component to resist degradation when exposed to water immersion which the component may experience during its service life. 1.2 General description The specimen is immersed i

21、n 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 capacity to permit the specimen to be appropria

22、tely immersed in water without violating other physical constraints (e.g. the minimum cable bend rad i us). 2.2 Water Distilled water. 2.3 Heat source A suitable heat source capable of achieving and maintaining the specified temperature within 12 OC of the required setting. 2.4 Oven A suitable oven

23、to dry the specimen during repeated immersion testing.

Perform any p

24、re-test measurements specified in the relevant specification. Unless otherwise specified, the 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 tha

25、t the specimen can be adequately immersed. The quantity of water shall be sufficient such that the device under test is 1 cm to 5 cm 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 te

26、st. 3.4 At the end of the specified period, remove the specimen from the bath. 3.5 The surplus water shall be wiped off and the specimen shall be allowed to dry at room temperature for 24 h without controlling its humidity following the removal from the immersion bath. 3.6 When the repeated immersio

27、n test is carried out, the surplus water shall be wiped off and the specimen placed in the oven to dry for 2 h at 40 OC. Before the next immersion, the specimen shall be allowed to stabilise at room temperature for 2 h. This procedure shall be repeated following subsequent immersions. 3.7 Upon compl

28、etion of the test, the specimen(s) shall be examined and all necessary observations recorded as specified 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, degrada

29、tion of optical characteristics, etc. 4 Severity The severity consists of 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 n

30、ot mandatory, may be specified for this procedure.
