2.1.7 Humidity effects2) (CH or no mark)
( Change in terms of due to Humidity effect on the indication of the minimum test load )
( Change due to Humidity effect on the indication of the maximum test load )
Remark: If the minimum or maximum test load used for this test differ from the minimum test load or maximum test load according to R 60-3, 2.1.2 “Load cell errors ” the conversion factor, , must be recalculated with the minimum and maximum test loads of this test (see R 60-3, 2.1.2.4).
2.1.7.1
From the test indications recorded in R 60-3, Table 6.10.1, calculate the difference between the initial indications for the minimum test load, , before and after the damp heat test and divide the result by conversion factor, , to obtain the change, , in terms of verification interval, (see R 60-1, 5.6.3.1).
2.1.7.2
Calculate the average indications and at (see R 60-2, 2.10.5) for the required number of test indications, before and after the damp heat test. Subtract from for the tests before and after damp heat test and then calculate the difference between the results. Divide the result by the conversion factor, , to obtain the change, in terms of .
2.1.7.3
must not exceed the MPE (see R 60-1, Table 4 in 5.3.2).
