How long can test plates be stored?

What are the respective storage periods for welding procedure qualification test plates, product welding test plates, and intergranular corrosion test specimens? Thank you so much!
It should be seven years, consistent with the production records.
The storage period for welding procedure qualification test plates is: until such procedure qualification is invalidated (that is, stored indefinitely). The storage period for product welding test plates is generally 3 years (they can also be treated in the same way as product documentation).
The storage period for welding procedure qualification test plates is: until such procedure qualification is invalidated. The storage period for product welding test plates is generally 7 years. The storage period for the intergranular corrosion test specimens should also be 7 years.

Welding procedure qualification test plates: Until such qualification becomes invalid. Product test plates: I thought it was 1 year; I seem to have read somewhere about this, but now I can’t find any evidence to support it. I hope I’m not dreaming
Same as the retention period for equipment records
The process evaluation test plates are retained until the evaluation is invalidated; product test plates and corrosion test specimens are determined according to the procedure documents
The storage period for welding procedure qualification test plates is until such qualification is invalidated. The storage period for product welding test plates is as follows: the samples are kept from the time the products leave the factory; generally, product samples are stored for three months, while samples for new products or those with a production cycle of more than six months are stored for six months.
Welding process qualification test plates are retained until such qualification is invalidated. The retention period for product welding test plates is as follows: samples are kept from the time the product leaves the factory; for ordinary products, the samples are retained for three months, while for new products or those with a production cycle of more than six months, the samples are retained for six months
For the welding procedure qualification test plates, the retention period for such plates until the relevant procedure qualification becomes invalid is as follows: the samples are retained starting from the time of product shipment; for ordinary products, the samples are kept for three months, while for new products or those with a production cycle of more than six months, the samples are retained for six months
