8-1

High

Temperature

After being placed in a thermal chamber with at

+85

±2°C for 1000 hours and then being placed at

ambient conditions for 8 hours, the transducer shall be

measured.

The measured values shall

meet Table 2

8-2

Low

Temperature

After being placed in a thermal chamber with at

-40

±2°C for 1000 hours and then being placed at

ambient conditions for 8 hours, the transducer shall be

measured.

The measured values shall

meet Table 2

8-3

Humidity

After being placed in a humidity chamber with

90 to 95

% R.H. at +60±2°C for 500 hours

and the being placed at ambient conditions for

8 hours, the transducer shall be measured.

The measured values shall

meet Table 2

8-4

Heat Shock

After being kept at room temperature, the transducer

shall be placed in a thermal chamber at temperature of

-40

°C.

After 30 minutes at this temperature, the transducer

shall

immediately

placed

chamber

temperature of

+85°C.

After 30 minutes at this temperature, the transducer

shall be returned to -40

°C again.

After 10 of the above cycles, the transducer shall be

returned to ambient conditions where it shall remain for

8 hours prior to being measured.

The measured values shall

meet Table 2
