Question:
" z1 {: l) r0 e9 ? N$ h; dIs it possible to simplify the making and breaking capacity and normal operation tests in a switch series rated 10 AX / 250 V with the same contacts and common mechanism?2 J" N3 j6 o# Y C. A. {8 D
Rationale:+ L" g# ]7 P8 d; t9 |5 Z# b
The switch series consists of the following pattern numbers:3 Y4 `6 D! T6 e& u6 B7 J R% _0 J
1, 1(push-button), 2, 1+1, 5, 6+1, 6/2, 6, 6+6, and 7 A common testing program facilitates the issue/recognition process of CB Certificates.) g, t" g, |8 |+ T
Decision:7 B' G) M" P4 n% o
It is acceptable to test the following pattern numbers:
0 K+ n7 l3 l) K& m- 1 or 1+1 (*): clauses 18 and 19;5 y. Q9 v# l! @8 Y
- 1 (push-button): clause 19.1;
