Foreword

The text of document 86B/2440/FDIS, future edition 2 of IEC 61300-2-22, prepared by SC 86B, Fibre optic interconnecting devices and passive components, of IEC TC 86, Fibre optics, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61300-2-22 on 2007-04-01

This European Standard supersedes EN 61300-2-22:1997

EN 61300-2-22:1997 specifies tests Na and Nb of EN 60068-2-14, however this EN 61300-2-22:2007 describes the test method of Nb and specifies “optional cycle” for some other performance categories The following dates were fixed:

– latest date by which the EN has to be implemented

at national level by publication of an identical

– latest date by which the national standards conflicting

Annexes ZA and ZB have been added by CENELEC

Endorsement notice

The text of the International Standard IEC 61300-2-22:2007 was approved by CENELEC as a European Standard without any modification

FIBRE OPTIC INTERCONNECTING DEVICES AND

PASSIVE COMPONENTS – BASIC TEST AND MEASUREMENT PROCEDURES – Part 2-22: Tests – Change of temperature

1 Scope

This part of IEC 61300 describes a procedure to determine the suitability of a fibre optic device to withstand the effects of a change of temperature or a succession of changes of temperature

The following referenced documents are indispensable for the application of this document For dated references, only the edition cited applies For undated references, the latest edition

of the referenced document (including any amendments) applies

IEC 60068-2-14, Basic environmental testing procedures – Part 2-14: Tests – Test N: Change

of temperature

This procedure is conducted in accordance with IEC 60068-2-14, test Nb The device under

test (DUT) is first subjected to one extreme of temperature for a given period of time It is then subjected to the other extreme of temperature for an equal period of time

4 Apparatus

The apparatus consists of suitable environmental chambers in accordance with IEC

60068-2-14, test Nb

The rate of change of temperature shall be: (1 ± 0,2) °C/min

5 Procedure

These procedures are in accordance with IEC 60068-2-14, test Nb

Unless otherwise stated in the relevant specification:

– include 1,5 m of cable in the climatic chamber for each port monitored during the test; – if optical measurements are requested during the test by the relevant specification, these measurements shall be performed (at a minimum) at the end of each dwell at each temperature extreme;

– allow dependence on wavelength scan time for components that require wavelength scanning

5.1 Preconditioning

Unless otherwise stated in the relevant specification, maintain the DUT under standard atmospheric conditions for 2 h minimum Clean the mechanical and optical alignment parts of the DUT according to the manufacturer's instructions

5.2 Initial measurements

Take initial examinations and measurements as required by the relevant specification

5.3 Testing

5.3.1 Place the specimen in the chamber in its normal operating position and make

connections to the monitoring equipment

5.3.2 Unless otherwise specified, the temperature profile in Figure 1 shall be applied Start

at standard atmospheric conditions and ramp down to the low temperature T at 1 °C/min A

Maintain the low temperature during t1 for a minimum of 60 min Ramp up to the high temperature T B at 1 °C/min Maintain the temperature during t1, then ramp down to the low temperature and repeat this profile for the required number of cycles

NOTE It is permissible to increase the dwell time at each extreme to allow sufficient time to perform a complete set of measurements

5.3.3 Optional cycle: for some performance categories, it may be necessary to ramp to the

high temperature first and include a dwell at room temperature between ramps to the extreme temperatures In this case, the profile in Figure 2 shall be applied

Start at standard atmospheric conditions and ramp up to the high temperature T at 1 °C/min

Then maintain the high temperature during t1 for a minimum of 60 min Ramp down to standard atmospheric conditions at 1 °C/min Maintain standard atmospheric conditions for a minimum of 60 min Ramp down to the low temperature T L at 1 °C/min Maintain that

temperature during t1 for a minimum of 60 min Ramp up to standard atmospheric conditions

at 1 °C/min and dwell for a minimum of 60 min The subsequent cycles will have the same pattern

5.4 Recovery

Allow the specimen to remain under standard atmospheric conditions for a period of at least

5.5 Final measurements

Record final measurements as required by the relevant specification Unless otherwise specified in the relevant specification, clean the DUT according to the manufacturer's instructions prior to recording final measurements

6 Severity

Each of the following severities consist of a combination of a low temperature with the corresponding high temperature and the corresponding number of cycles One of them shall

be specified in the relevant specification:

7 Details to be specified

The following details, as applicable, shall be specified in the relevant specification:

– severity;

– initial examinations and measurements and performance requirements;

– examinations and measurements during test and performance requirements;

– final examinations and measurements and performance requirements;

– deviations from test procedure;
