Hose couplings with batch number
At Alfotech, we supply hose couplings with batch numbers. In the picture you can see an example of a printed text. P08 means that the hose is pressure-tested to 8 bar. 23/08 means that the part was manufactured in week 23 in 2008. "Sukker nr. 2" is individual text chosen by the customer.
Keeping documentation for food contact materials for a period of 5 years is recommended, unless special circumstances may justify otherwise.
