hello , everyone
we want to manufacture stainless steel filter bags internally by ourselves is that the BRC requires a certificate of guarantee for the filter bags too? we are in the refining of the oil industry, and the filter bags consists in filtering the incoming oil while keeping its constant temperature thanks to the hot water which surrounds the filter bags, (normally the risk incurred is the passage of the heating water in oil) but we will perform tests before launching production
do you guys think that we would need a certificate of guarantee or just tests recording ?
