We determine the following keg qualities using state-of-the-art measuring equipment and working together with a material testing institute:
The surface roughness of the material coming into contact with beer is determined in µm as per DIN 6647.
The kegs are cracked using special pumps, and the maximum pressure documented.
The maximum volume of a used keg is determined using calibrated measuring equipment.
The keg’s dimensional stability is determined and documented in accordance with DIN standards.
