Scope and field of application

This standard specifies general tolerances and machining allowances for rough castings of aluminium and magnesium alloys produced by sand casting, which are subject to the technical delivery conditions laid down in DIN 1725-2 and DIN 1729-2.

Users of this standard should note that it now only applies to castings used for repair and replacement purposes. New designs are covered by IS0 8062 : 1994.

Owing to the lack of empirical data, general tolerances have not been specified here for angular dimensions. If angles are to meet accuracy requirements, these shall be indicated as individual tolerances.
