IEC 60924:1990/AMD1:1993

This part of IEC 61347 specifies particular safety requirements for d.c. supplied electronic ballasts intended for operation from power sources likely to have attendant transients and surges, for example, for road and railway vehicles, tramcars, and craft used for public transport. This first edition of IEC 61347-2-5, together with IEC 61347-1, cancels and replaces section four of the first edition of IEC 60924, published in 1990, and constitutes a minor revision. This standard shall be used in conjunction with IEC 61347-1. It was established on the basis of the first edition (2000) of that standard.

This part of IEC 61347 specifies particular safety requirements for d.c. supplied electronic ballasts intended for operation from transient and surge-free power sources, operated directly from batteries without charging equipment as used in leisure equipment, for example, caravans, etc. This first edition of IEC 61347-2-4, together with IEC 61347-1, cancels and replaces section three of the first edition of IEC 60924, published in 1990, and constitutes a minor revision. This standard shall be used in conjunction with IEC 61347-1. It was established on the basis of the first edition (2000) of that standard.

This part of IEC 61347 specifies particular safety requirements for d.c. supplied electronic ballasts intended for operation from power sources likely to have attendant transients and surges such as in aircraft. This first edition of IEC 61347-2-6, together with IEC 61347-1, cancels and replaces section five of the first edition of IEC 60924, published in 1990, and constitutes a minor revision.
