CEI 255 is the Spanish version of IEC 60255, Electrical Relays. IEC 60255-5 covers the insulation tests, but I have no knowledge of IEC 60255-4. IEC 60255-22-4 covers Electrical Fast Transient testing for relays; this may be what CEI 255-4 is referring to.
My Spanish is not very good, but 4.1 describes the insulation tests and 4.2 describes immunity tests.

I am assuming that these are "IEC" specifications. As a matter of fact, the text reads (forgive my Spanish spelling) CONDICIONES ELECTROMAGNETICAS (I think I can figure this line out :-) Toda las bornas y conectores dberan ser capaces de superar las siguientes condiciones sin midificar su rendimiento de trabajo. 4.1 Aislamiento: 2KV/50hz/1m. segun norma CEI 255-5 4.2 Pertubaciones Impulso de tension 5KV segun norma CEI 255-5 Interferencias de A.F. 2.5KV en modo longitudinal Interferencia de A.F. 1KV en modo transversal, segun norma CEI 255-4; apartado E. Anybody want to fathom a guess at this? My catalog of standards does not include either a CEI 255 or an IEC 255. Gracias!!!! Chris Maxwell a.k.a.
