This standard is applicable for spring band clamps (FBS) made of tempered spring band steel for fastening hoses to mobile and stationary systems for use in a temperature range of -40 °C to + 150 °C, e.g. B. in the areas of coolant circuit and servo system up to 300 kPa (3 bar) overpressure, fuel system up to 700 kPa (7 bar) overpressure, air intake system underpressure, charge air system up to 200 kPa (2 bar) overpressure, for sealing the hose-socket connection. Spring band clamp, hose and connector form a system.*This document is applicable for spring band clamps (FBS) made of tempered spring band steel for fastening hoses to mobile and stationary systems for use in a temperature range of - 40 °C to + 150 °C, for example in the areas of coolant circuit and servo system, fuel system, air intake system, charge air system, for sealing the hose-socket connection. The new version of DIN 3021-1 updated the normative references and literature references, and in Section 6 a reference was made to the leak test according to DIN 3021-2:2023-05, 4.8, as well as to the requirements for the spring band clamp-hose system. Socket according to DIN 3021-3:2023-05, 4.1, included. Finally, the text was edited.
