22、edure to determine the suitability of a fibre optic device or closure to withstand the environmental condition of extended high temperature that may occur during operation, storage and/or transport. The test is intended to indicate the performance of such devices when exposed to heat of constant tem
23、perature over a given period. In general terms, this test provides a high temperature to induce potential failures due to softening and expansions. This procedure does not assess the ability of a device to operate during temperature variations; in this case, IEC 61300-2-22 would be used. 2 Normative

27、 This procedure is conducted in accordance with IEC 60068-2-2, test Bb. The specimen is placed in an environmental chamber and subjected to a dry heat environment, which is maintained at a given temperature for a specified duration, as defined in the relevant specification. If required, the attenuat
28、ion of the specimen is monitored throughout the duration of the test. EN 61300-2-18:2005 4 4 Apparatus 4.1 Chamber The apparatus shall consist of an environmental chamber in accordance with IEC 60068-2-2, test Bb. The chamber shall be capable of housing the specimen and of allowing access for measur
29、ement during conditioning, if required. It shall also be capable of maintaining the specified temperature and humidity within the specified tolerances. Forced air circulation may be used to maintain homogeneous conditions. Care shall be taken to ensure that the specimen is not directly exposed to th
30、e heating or cooling elements. 4.2 Optical source and detector The optical source and detector used to measure changes in attenuation shall comply with those specified in IEC 61300-3-4. NOTE A device to record attenuation over time (X, t) should be used where the optical detector does not have the c
31、apability to monitor continuously. 5 Procedure Conduct the procedure in accordance with IEC 60068-2-2, test Bb. Unless otherwise stated: if the component construction includes optical leads, include 1,5 m of cable in the climatic chamber for each port monitored during the test; If optical measuremen
32、ts are requested during the test, these measurements shall be performed at a maximum interval of 1 h. 5.1 Preconditioning Clean the mechanical and optical alignment parts of the specimen according to the manufacturers instructions. Unless otherwise stated, maintain the specimen under standard atmosp
33、heric condition (room temperature condition) for 2 h minimum. 5.2 Initial examinations and measurements If specified, perform initial examinations and measurements as required by the relevant specification. 5.3 Conditioning 5.3.1 Set the chamber and the specimen to standard atmospheric conditions. P
34、lace the specimen in the chamber in its normal operating position including hook-ups to peripheral equipment (when required). 5.3.2 Adjust the chamber temperature and humidity to the specified severity. The rate of change of temperature shall not exceed 1 C/min, averaged over a maximum period of 5 m
35、in. Allow the specimen to reach temperature stability and maintain the temperature for the duration specified. 5.3.3 At the completion of the test, allow the specimen to remain in the chamber while the temperature is gradually reduced to standard atmospheric conditions. EN 61300-2-18:2005 5 5.3.4 Wh
36、ere optical measurements are required during the test, measurements shall be made at a maximum interval of 1 h. Measurements shall be made in accordance with IEC 61300-3-3 regarding monitoring change in attenuation and return loss. 5.4 Recovery Allow the specimen to remain under standard atmospheric
37、 conditions for a period of greater than 2 h. 5.5 Final examinations and measurements On completion of the test, remove all fixtures and make final measurements, as defined by the relevant specification, to ensure that there is no permanent damage to the specimen. The results of the final measuremen
38、t shall be within the limit established in the relevant specification. Unless otherwise specified, visually examine the specimen in accordance with IEC 61300-3-1. Check for evidence of any degradation in the specimen. This may include, for example broken, loose or damaged parts or accessories; break
39、ing or damage to the cable jacket, seals, strain relief, or fibres; displaced, bent, or broken parts. 6 Severity The severity consists of the combination of the temperature and exposure time. The severity shall be specified in the relevant specification. One of the severities indicated in Table 1 sh
40、all be specified for this procedure: Table 1 Severities Temperature C Duration of exposure h + 60 +70 +85 96 7 Details to be specified The following details, as applicable, shall be specified in the relevant specification: temperature; duration of exposure; initial examinations and measurements and
41、performance requirements; examinations and measurements during test and performance requirements; final examinations and measurements and performance requirements; deviations from test procedure; additional pass/fail criteria.
