Classification of wiring pipes according to EN 50 086

The four digit code classifies the conduits and their accessories according to compressive strength, impact strength, minimum and maximum admissible installation temperature.

first digit		second digit		third digit		fourth digit
compressive strength		impact strength		lowest admissible temperature		highest admissible temperature
1	very low 125 N	1	very low 0,5 J	1	+ 5 °C	1	+ 60 °C
2	low 320 N	2	low 1 J	2	- 5 °C	2	+ 90 °C
3	medium 750 N	3	medium 2 J	3	- 15 °C	3	+ 105 °C
4	high 1250 N	4	high 6 J	4	- 25 °C	4	+ 120 °C
5	very high 4000 N	5	very high 2,4 J	5	- 45 °C	5	+ 150 °C
						6	+ 250 °C
						7	+ 400 °C
