HDC2010: How to validate the accuracy of HDC2010 Temperature sensor

Hello,

I am using HDC2010 Temperature & Humidity sensor.

I want to validate the accuracy of +/- 0.2 ^oC.

In our Temperature chamber I created a profile from +25 ^oC to -25 ^oC as below

1) 25 ^oC to 20 ^oC will be reached within 5 minutes ( 1 ^oC per 1 minute) and then at 20 ^oC wait for 10 minutes.

2) 20 ^oC to 15 ^oC will be reached within 5 minutes ( 1 ^oC per 1 minute) and then at 15 ^oC wait for 10 minutes.

Above steps will be continued till below

n-1) -15 ^oC to -20 ^oC will be reached within 5 minutes ( 1 ^oC per 1 minute) and then at -20 ^oC wait for 10 minutes.

n)    -20 ^oC to -25 ^oC will be reached within 5 minutes ( 1 ^oC per 1 minute) and then at -25 ^oC wait for 10 minutes.

Is above procedure is right or if there is any other alternate approach, please let me know. We have a stringent temperature accuracy requirement.

 Can you please share your test procedure with respect to Temperature & Humidity sensor accuracy.

Thanks & Regards
