Confirmed by CTL at its 39th meeting, in Cologne
Question:
56.1 b) requires that ratings of components shall not conflict with the conditions of use in
EQUIPMENT. There are no requirements for components themselves to meet specific
standards which include the control of reliability.
Decision:
It is strongly recommended that components in the MAINS PART and in APPLIED PARTS
" }8 T8 I, Q6 e* y& P+ s" sshould comply with recognised component standards, consistent with their use. The following
hierarchy of acceptable standards is suggested:
1 p. T" P2 L8 h+ f$ a5 p1. International standards (e.g. IEC, ISO etc.)
. l  Q4 U. b$ g2. National standards (e.g. BSI, DIN, UL etc.)
