Abrasion – standards
The wear-resistance quality of a conveyor belt is usually the single most important factor that will determine its operational lifetime and, consequently, its cost-effectiveness. There are two internationally recognized sets of standards for abrasion, EN ISO 14890 (H, D and L) and DIN 22102 (Y, W and X). As mentioned earlier, in Europe it is the longer-established DIN standards that are most commonly used. Generally speaking, DIN Y relates to ‘normal’ service conditions and DIN W to particularly high levels of abrasive wear. However, DIN X is regarded as the most versatile because, in addition to resisting abrasive wear, it also has good resistance to cutting, impact (from high drop heights) and gouging (usually caused by heavy, sharp materials).
