27、he values specified in Table 2 for the heat analysis. 6.2.2Product analysis In cases where a product analysis is requested, the admissible deviations from the values specified for the heat analysis are indicated in Table 3. 6.3 Mechanical properties The mechanical properties of the products, to be d

28、etermined by the tensile test, shall be in accordance with the prescriptions given in Tables 4, 5, 6 and 7. 6.4Surface quality 6.4.1Rod is normally supplied in the pickled condition. Mechanical descaling (sandblasting) can also be used, in which case a subsequent treatment in a pickling solution sha

29、ll be carried out unless otherwise agreed. Particular processes such as peeling can also be applied, subject to specific agreement at the time of enquiry and order. 6.4.2Minor surface imperfections that may occur under normal manufacturing conditions, such as scores originating from rolled-in scale,

30、 shall not be regarded as defects. 6.4.3Any particular surface requirements may be agreed at the time of enquiry and order. 6.5Supplementary or special requirements 6.5.1 Aptitude to cold forming A test for the verification of the aptitude of products to cold forming may be carried out if agreed at

31、the time of enquiry and order. If for the verification of the aptitude to cold forming the upsetting test is applied, it shall be carried out as follows: a test piece with an initial length (height) equal to 1,5 d, where d is the product diameter, is submitted to axial heading by means of a press un

32、til its length is reduced to 1/3 of the initial value. The above test shall be carried out at ambient temperature and limited to the products with a max. diameter of 15 mm. The criteria for the assessment of test results shall be agreed at the time of ordering bearing in mind the end use for which t

33、he products are intended. 6.5.2Depth of surface defects The max. admissible depth of surface defects is indicated in Table 8. The depth of a defect is considered as being the distance between the surface of the product and the bottom of the defect, to be measured in a direction perpendicular to the

34、surface along a radius. In case of dispute the determination of the depth of surface defects shall be carried out by metallographic means with a magnification of X 100, on a straight cross-section of the product in the delivery condition concerned.
