The permissible deviations of the product analysis in relation to the actual heat analysis are given in Table 2. 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 Depth of surface defects The rod shall not have any surface discontinuities of depth greater 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). 3.4 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: DIN 50 602:1985 Metallographische Prufverfahren Mikroskopische Prufung von Edelstahlen auf nichtmetallische Einschlusse mit Bildreihen; NF A 04-107:1980 Produits sidérurgiques Méthode micrographique de détermination de la teneur en inclusions non-métalliques du fil-machine en acier non allié UNI 3244:1980 (with annex) Esame microscopico dei materiali ferrosi Valutazione delle inclusioni non metalliche negli acciai mediante immagini tipo; ASTM E 45:1987 Standard practice for determining the inclusion content of steel.
