Regarding the handling regulations for product welding test specimens and remaining specimens, the general manual stipulates that the physical and chemical rooms should be kept for 3 to 6 months. Can any of you remember where this time comes from?
The specifications for process assessment are required to be permanently preserved.
It is estimated that we have to go back more than 20 years from this time to find it.
