What samples are to be selected in case of family products?
Decision:
Ballast for tubular fluorescent lamps and discharge lamps. In general it is necessary to carry out the tests
on all the types of ballasts with the following exceptions:
- resistance to heat, fire and tracking - it is possible to test only one type of ballast if the
materials used are identical;
- thermal endurance of winding, (clause 13 IEC 61347-2-8/2-9) – for ballasts of the same
) x- y' y  a) \* \1 x9 lseries is sufficient to carry out the test on samples of minimum rated wattages and on the
maximum one. All the intermediate wattages are considered extensions.
( S- a! _+ W; T  p, _The ballasts are considered of the same series if:
- they are covered by the same standard, (e.g. IEC 61347-2-8/2-9);
- they are of the same construction. It means that they have laminations or cores with identical
pattern range, with the same insulating material;
- they have an equal assembly technology;
