34、old formingA test for the verification of the aptitude of products to cold forming may be carried out if agreed at 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 len

35、gth (height) equal to 1,5 x d, where d is the product diameter, is submitted to axial heading by means of a press until 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 maximum diameter of 15 mm.The criter

36、ia for the assessment of test results shall be agreed at the time of ordering bearing in mind the end use for which the products are intended.6 BS EN 102635:2017EN 102635:2017 (E)6.5.2 Depth of surface discontinuitiesThe maximum admissible depth of surface discontinuities is indicated in Table 9. Th

37、e depth of a discontinuity is considered as being the distance between the surface of the product and the bottom of the discontinuity, to be measured in a direction perpendicular to the surface along a radius. In case of dispute the determination of the depth of surface discontinuities shall be carr
