1 Scope
This technical specification introduces safeguards to reduce the likelihood of room flash-overas a result of accidental ignition of exterior housings of audio/video and informationcommunication technology products likely to be used in the home, caused by a candle flame.
NOTE According to AC/22/2009 and SMB decision 135/20, this technical specification should currently only beused for television sets. lt can be used for other products only if a risk assessment indicates problems with theseproducts.

3 Terms and definitions
3.1
combustible material
organic material, capable of combustion by a candle flame
NOTE 1 Metal or ceramic are examples of materials that are not combustible by a candle flame.
NOTE 2 A plastic materials are considered combustible by a candle flame, regardless of flammabilityclassification.
3.2
flammability classification of materialsclassification of the burning and extinguishing behaviour of a material
NOTE 1 Material classes are defined in 3.2.1 to 3.2.4. Where a certain class of material is required, a materiawith a better classification is always acceptable
NOTE 2 When applying the requirements in this technical specification, a material of 5VA class material isregarded as better than 5VB class material, 5VB class material beter than V-0 class material and V-0 classmaterialbetter than V-1 class material (see 5.1).
NOTE 3 When applying the requirements in this technical specification, V-2 class material or HB class material isconsidered less than V-1 class materlal (see 5.1). For further detals regarding these flame classifications, seeIEC 60695-11-10.

material tested in the thinnest significant thickness used and classified V-0 according to IEC 60695-1 1 -1 0
3.2.2
V-1 class material
material tested in the thinnest significant thickness used and classified V-1 according to IEC 60695-1 1 -1 0
3.2.3
