Specifications
7.1 Mechanical
Strength and Ease of Control
7.1.1 Mechanical
Strength
Set exterior parts such as lens, buttonsetc, shall be able to withstand a force of 50N during 30 seconds from all
possible directions. The rigid test finger, according to IEC60065 clause: 9.1.8 should be used.
Set shall be proof against a pinch force of 150N, loaded by a bare hand. The product shall give a rigid
impression and shall not produce any annoying mechanical noise.
7.1.2
Rigidity of Top Surface
Set top must be able to withstand a force of 100N for duration of at least 30 seconds.
This force has to be applied by means of a flat plane of 4cm
2
(a plane with dimensions of 2cm x 2cm) at all
places at the top side.
7.1.3
Regularity of Operating Forces for Touch Control
Deviations in the regularity of the operating force of touch control shall not be perceptible by hand.
7.1.4
Moving of Set during Operation
Set shall not move (slide backwards) whilst operating the touch control on the set or inserting disc.
7.1.5 Maximum
Temperatures
The maximum permissible temperature rises of the various external parts of a product are mentioned in the next
table.
The values of the temperature are based upon the maximum ambient temperature of 35
°
C.
The temperatures have to be measured after an operation time of 4 hours.
Maximum temperature rises with respect to the max ambient temperature.
