Durability
Item Vibration Conditions Only endurance conditioning by a frequency sweep shall be made. The entire frequency range, from 10Hz to 55Hz and return to 10Hz shall be transversed in 1 min with an amplitude (total excursion) of 1.5mm. This vibration shall be applied for a period of 2h in each of 3 mutually perpendicular axes (a total of 6h). Refer to IEC Pub. 68-2-6 for other procedures. Peak acceleration : 40G Duration of pulse : 6ms Three successive shocks shall be applied in both directions of 3 mutually perpendicular axes (a total of 18 shocks). Refer to IEC Pub. 68-2-27 for other procedures. The specimen shall be stored at a temperature of -25±3�C for 6h and then subjected to standard atmospheric conditions for 1h. After this procedure, measurements shall be made. Refer to IEC Pub. 68-2-1 Test Ab for other procedures. The specimen shall be stored at 85±2�C for 6h and then subjected to standard atmospheric conditions for 1h. After this procedure, measurements shall be made. Refer to IEC Pub. 68-2-1 Test Bb for other procedures. The specimen shall be stored at 40±2�C and a relative humidity of 90% to 95% for 96 +4h and then subjected to standard atmospheric conditions for 1h. After this procedure, measurements shall be mode. Refer to IEC Pub. 68-2-3 for other procedures. The specimen shall be subjected to 5 continuous cycles, each as shown in the table below. Following the final cycle, the specimen shall be stored at standard atmospheric condition for 1h, after which measurements shall be made. Temperature -25 ±3�C Standard atmospheric conditions 70 ±2�C Standard atmospheric conditions Duration 30 min. 10 to 15 min. 30 min. 10 to 15 min.
