" U; X& m3 {# O5 mon all the types of ballasts with the following exceptions:
/ ]% P1 t, D, B% d3 O- 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
series 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.
/ t' K; s; C- I. e; |# tThe ballasts are considered of the same series if:
