1000
Belt width in mm
EP
Carcass material *)
630
Belt min. breaking strength in kN/m
4
Number of plies
6
Top cover thickness in mm
2
Bottom cover thickness in mm
Y
Cover grade
*) Note 1: In some regions, PN is used instead of EP, where P stands for Polyester and N for Nylon.
Note 2: For textile conveyor belts it should additionally be indicated whether solid, sealed or cut edges are preferred.
Example for a solid woven carcass designation:
4-ply belt
2-ply belt

Cover grade
t = pitch, d = diameter, bk = edge width, B = belt width, s1 = belt thickness, s2 = top cover thickness, s3 = bottom cover thickness, s4 = thickness between steel cords and protection layer, bt = tension width, 1 = protection layer,
Notes:
*) A requirement of DIN standards for steel cord conveyor belts is that the breaking force of a vulcanized steel cord in the conveyor belt shall be at least as great as the product of the minimum breaking strength of the conveyor belt by the cord spacing with an addition of approximately 10%.
**) The exact construction of a textile damage protection system, above referred to as "T", is not standardized.
In some world regions it is common to ignore norm values like minimum breaking strength (meaning that not a single test value must be below the agreed minimum). Sometimes the "root mean square" method is used, where the average value may be above the minimum in spite of individual unacceptable low figures.
*) Other grades are E (antistatic), K and S (antistatic and flame retardent), T (high temperature resistant), R (low temperature resistant), G (oil and fat resistant) and C (chemical resistant).
The physical data for such grades need to be agreed upon between user and manufacturer.
The above data are given without obligation. Please use the data of the latest relevant standard/norm.
