1 Scope This standard specifies the classification and designation, technical requirements, test methods, inspection rules, marking of castings, surface protection, packaging, storage and transportation requirements of malleable iron castings. This standard is applicable to malleable iron castings cast into sand moulds or moulds of comparable thermal conductivity. Other mold casting malleable iron castings may use it by reference. 2 Normative References The following standards contain provisions which, through reference in this standard, constitute provisions of this standard. For dated reference, subsequent amendments to (excluding correction to), or revisions of, any of these publications do not apply. However, the parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards. For undated references, the latest edition of the normative document referred to applies.

Metallographic structure of pearlite malleable cast iron: mainly of pearlitic matrix + group flocculent graphite. 3.1.2 White heart malleable cast iron The metallographic structure of white heart malleable cast iron is dependent on section size, as described below. Figure 1 shows the metallographic structure changes depending on the thickness of the casting wall. a) Thin section = ferrite (+ pearlite + graphite aggregate); b) Thick section see Figure 1.
