Temperatures

The next three test periods determine how much the rate varies between three different temperatures — 8°, 23° and 38°C. Excessive changes in the rate could show that the balance-spring alloy is not up to standard.:D

The temp. test will show if the allow was not mixed in the proper proportions or just mixed enough to get a homogeneous mixture.  Have not read the attachments but will when I have a second. It will also show that the corect lubricants were used at the proper locations, to viscous will slow a irregular amount at -8 deg C.
