DCR Item 1a) is modified as follows: ‘Tamb = +25 ±1°C’ shall be deleted for Frequency-Load Tolerance (i.e., thereby deferring to the default test temp: Tamb = +25 ±3°C)

DCR item 2) due to software issues not permitting the addition of an equation to the DCR form, the final sub-paragraph of item 2 should be as follows:


e.g. The frequency change over the period of 1 year (365 days) for a total ageing measurement period of Ta, in days (whereTa is 30 days or longer), is given by the equation shown in the attached spec mark-up.
