4.9 Endurance test procedure
4.9.1 Standard aging test for production verification
4.9.1.1 Purpose
This test is usable for the statistical verification of aging performance in the production
process.
IEC 60122-1:2002/AMD1:2017 – 3 –
© IEC 2017
4.9.1.2 Procedure
– Take sample from the production lot.
– Initial measurement of f and R at (25 ± 2) °C.
s 1
– Store in oven at T = (+85 ± 3) °C.
oven
– Take and record additional measurements after 1 day and at least three more times at
time intervals recommended in Annex A.
– For the measurement, remove the crystals from oven, and store at room temperature for
1 h, avoiding temperature shocks. Measurement of f and R at (25 ± 2) °C in accordance
s 1
with IEC 60444-5 or equivalent.
– Final measurement of f and R at (25 ± 2) °C after 30 days.
s 1
4.9.1.3 Evaluation
The difference between the highest and lowest frequency measurement shall not exceed the
specified value. The resistance R shall never exceed the specified maximum values.
4.9.2 Accelerated aging
4.9.2.1 Purpose
For special applications, an accelerated aging procedure at higher temperatures is applied to
shorten the verification time and/or to gain performance data at higher operating temperatures.
4.9.2.2 Procedure
The procedure is as in 4.9.1, except that the preferred oven temperature is T = +105 °C,
oven
+125 °C or +150 °C. This temperature has to be lower or equal to the specified maximum
storage temperature.
The ratio between the storage time at 25 °C and the storage time at an elevated temperature
T to achieve the same amount of frequency aging is called "time acceleration factor"
oven
(TAF). This factor depends on the design of the crystal unit and on the production process. It
can be determined experimentally as described in Annex A, or taken from experience with
structurally similar crystals, or can be mutually agreed between the manufacturer and the user.
If the time acceleration factor TAF is not otherwise specified, the following approach is
recommended.
Applying Arrhenius’s law, the time acceleration factor TAF is related to the activation energy
E (in eV) by the following equation:
a
1 1
E ⋅ −
a
T T
ref oven
k
TAF= e
where
−5
k is Boltzmann’s constant (k ≈ 8,617 × 10 eV/K), and the temperatures are given in K.
Published experimental results (see [6] and [7]) show that the activation energy E is
a
decreasing over time, i.e. the acceleration factor becomes lower with the aging time.
Furthermore, E varies between the different crystals and oscillators, depending on frequency,
a
package size, resonator design and production processes. The observed values of E were
a
between > 0,1 eV and < 1 eV.

A common assumption is TAF = 12 for T = +85 °C, i.e. 30 days (1 month) aging at 85 °C
