17、 following identification markings : - number of material standard, - producers trade mark, - batch number, - inspector Is stamp a lO,2 Marking methods The products shall be marked ordin to any s cia1 CU tom require.- ments. In the absence of these the products shall be marked by stamping at a posit

The ink used for marking shall not be corrosive even during subsequent heat treatments, It shall be possible to remove it completely. If the cross section is too small for this individual marking the products a

I3 ACCEPTANCE Final inspection including the selectLon, preparation and testing of test pieces shall be carried out at the producers works. If the customer so requires, the date

20、proposed by the producer for undertaking these requirements shall be noti- fied to any agent responsible for acceptance, to whom the instructions concer- ning the relevant order are to be supplied, 12 INSPECTION REPORTS I The producer shall prepare an inspection report, specified by standard Eh2078
