EN 10016-4:1994 © BSI 06-19995 Table 2 Permissible deviations in the product analysis in relation to the actual heat analysis 3.2 Internal soundness and surface quality The rod shall have no internal and/or surface imperfections such as: shrink holes, segregation, cracks, folds, incrustations, notches, scabs, rolling burrs, damage, which may be prejudicial to its correct use. 3.3 Soundness The rod shall not have any surface discontinuities of depth greateer than the values shown in Table 3. These limit values apply for the test chosen according to EN 10016-1 (clauses 9.5.1 and 9.6.2). Table 3 Limit values for the depth of surface discontinuities 3.4 Depth of decarburization The specifications given below concerning the depth of decarburization and the inspection procedure relating to it only apply to grades C42D2 to C98D2. 3.4.1 Complete decarburization The rod shall not display complete decarburization. 3.4.2 Partial decarburization The rod shall not display partial decarburization of depth greater than the values given in Table 4. The maximum point of decarburization shall not exceed twice the limit of Table 4. These limit values are applicable for the test described in EN 10016-1 (clause 9.5.2). Table 4 Limit of the depth of partial decarburization 3.5 Inspection of non-metallic inclusions The method for inspecting non-metallic inclusions and the assessment criteria for it shall be agreed at the time of ordering, as far as possible with reference to the ENV 10247 or to one of the following standards: 3.6 Core segregation If so agreed at the time of enquiry and order, rod of grade C60D2 or grades with a higher carbon content shall be inspected for carbon segregation. Not more than 10 % of the samples tested shall be of class 4; class 5 is not allowed (see EN 10016/1, Annex A). It is recommended to do the evaluation as part of a quality assurance system. 3.7 Mechanical properties At the request of the purchaser at the time of ordering, the manufacturer shall notify indicative values of tensile strength. The permissible variation on the values agreed at the time of ordering shall not exceed the values reported in Table 5.
