7.5 Support
Foot
7.5.1
Type of material
Refer to MUS [3] for the type of material used.
1. Material for the support foot cannot shrunk in such a degree, e.g. after the Cyclic Humidity Test of 21
x 24 hours, that the set touches the furniture or other equipment during shifting. Minimum of 1mm
height should still be attained.
2. Material of the support foot cannot leave stains on furniture surfaces after climatic tests e.g. 70deg x
96hr.
3. The support foots shall prevent the set from moving over the underneath surface while normally
operating the set.
