Aerospace series - Fibres and cables, optical, aircraft use - Test methods - Part 410: Thermal life
This European Standard specifies a method of measuring the thermal endurance of a finished optical cable. There are two test methods incorporated which estimate the cables thermal life with or without the cable.
- Method A - without mechanical stress (temperature only),
- Method B - combined temperature and mechanical stress.

Aeronavtika - Optična vlakna in kabli za uporabo v zračnih plovilih - Preskusne metode - 410. del: Življenjska doba pod temperaturnim vplivom
Ta evropski standard določa metodo za merjenje toplotne vzdržljivosti končanega optičnega kabla. Dve preskusni metodi sta uporabljeni za oceno življenjske dobe toplotne vzdržljivosti kabla s kablom ali brez njega.
– Metoda A: brez mehanskih obremenitev (samo temperatura).
– Metoda B: združene toplotne in mehanske obremenitve.
