23、t 1: General requirements. 3 Manufacture Remelting stock shall be manufactured from a melt consisting of: 1) pure materials and added elements, or 2) pure materials, added elements plus a defined and constant percentage of approved scrap, or 3) pure materials, added elements and approved scrap. Thei
24、r proportion per melt is at the option of the manufacturer. Unless otherwise specified on the order or manufacturing schedule, the manufacturing method3) shall be applied. 4 Dimensions and tolerances The form, mass, dimensions and tolerances of remelting stock shall be defined by agreement between t
25、he manufacturer and purchaser. The frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify compliance with the requirements. 5 Internal defects Remelting stock shall not contain defects prejudicial to its intended use. Unless otherwise agreed between the man
26、ufacturer and the purchaser and stated on the order or in the inspection schedule, test methods and acceptance criteria shall be at the option of the manufacturer. The frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify compliance with the requirements.
27、6 External defects Remelting stock shall be visually examined and shall be free from corrosion, scale, slag, grease or any other foreign matter including paint, other than that approved for marking. The frequency of examination adopted by the manufacturer shall be sufficient to permit him to certify
28、 compliance with the requirements. 7 Chemical composition See EN2103-1. 8 Number of test samples Sufficient test samples shall be provided and prepared from each batch in accordance with the requirements of EN2103-1 for the tests required by the material standard or inspection schedule. 9 Mechanical
29、 testing Tensile test, creep rupture test, creep test required by the material standard shall be made at a frequency of one test per batch. Tensile testing at ambient temperature shall be carried out in accordance with EN2002-1. Tensile testing at elevated temperature shall be carried out in accorda
30、nce with EN2002-2. Creep and creep rupture testing shall be carried out in accordance with EN2002-5. Test results shall comply with the requirements of the material standard. 10 Special tests See EN 2103-1. For example: dross test, fracture test. 1) Published as AECMA pre-standard at the date of pub
