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
14、-2-22:2007 describes the test method of Nb and specifies “optional cycle” for some other performance categories.

IEC 60068-2-14, Basic environmental testing procedures Part 2-14: Tests Test N: Change of temperature 3 General description 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
21、 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
22、 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
23、 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. EN 61300-2-22:2007 4 5.1 Preconditioning Unless otherwise stated in the relevant specification, maintain the DUT under standard at
24、mospheric conditions for 2 h minimum. Clean the mechanical and optical alignment parts of the DUT according to the manufacturers 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 ch
25、amber 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 AT at 1 C/min. Maintain the low temperature d
26、uring t1for a minimum of 60 min. Ramp up to the high temperature TBat 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. t1t1TBTAA First cycle Second cycle Time t Temperature in the chamber IEC 263/07 A = star

Figure 1 Temperature profile 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 in
28、clude 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 t1for a minimum of 60 min. Ramp do
29、wn to standard atmospheric conditions at 1 C/min. Maintain standard atmospheric conditions for a minimum of 60 min. Ramp down to the low temperature TLat 1 C/min. Maintain that temperature during t1for a minimum of 60 min. Ramp up to standard atmospheric conditions at 1 C/min and dwell for a minimum
