Parameter
Test Method and
Conditions
Damp heat,
cyclic
85°C and 95% RH;
(Ref.
IRef. IEC 60068-
2-3)
Specification: 8x15x1.5 HAC Receiver
Order No. 2403 263 00092
Revision: A1.5.1 / 04.29.11
Duration
168hrs
Evaluation Standard
Measurements of acoustic
parameters shall be still
within specification.
Allowed deviations:
Sensitivity is allowed to be
within +/-3dB from initial
value;
The distortion shall not
increase by more than a
factor of 1.4 of the initial
value measured at a single
frequency bin.
E.g.: distortion at frequency
bin 400Hz which is initially
10% is allowed to be 14%
after the test.
