In the absence of these the products shall be marked by stamping at a posit
18、ion which does not interfere with their use, or by multiple marking with roller or stamp. 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
19、re supplied in bundles and indelibl8.marking shall then be applied to a sufficiently strong label attachedto each bundle. 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
