Sample, rough specimens and test pieces selected in accordance with AnnexA shall be considered to berepresentative of the product.
NOTE As a result of their production sequence, e.g.melting, casting hot or cold forming or both, heattreatment, etc., steel products are not homogeneous. The mechanical properties of samples taken from otherlocations can be different.
4.2 ldentification of sample products, samples, rough specimens and test pieces
Sample products, samples, rough specimens and test pieces shall be marked to ensure traceability tothe original product and their location and orientation in that product. For this purpose, if, during thepreparation of any one or more of the samples, rough specimens or test pieces, removal of the markscannot be avoided, transfer of these marks shall be carried out before the existing marks are removedor,in the case of automatic preparation, equipment before the test piece is removed from the equipment.In the case of specific inspection and where requested by the purchaser, the transfer of the marks shallbe carried out in the presence of the purchaser’s representative.
ln the case of fully automatic in line preparation and testing systems, marking of samples, roughspecimens and test pieces is not necessary if an adequate control system exists, which defines theprocedures to follow in the event of system failure.ISO 377 pdf download.
