* Apparatus classified in a temperature class is deemed to be suitable for use in gases and vapours appropriate to that and lower temperature classes. For instance, a lamp reaching a temperature of 130 °C would be marked T4. That temperature would not ignite

the gases or vapours in the T4 row; neither would it ignite the gases or vapours in the T3, T2, or T1 rows. However, that temperature would ignite gases or vapours in the T5 or T6 rows, such as carbon disulphide.
