Standard Specification for Common Requirements for Iron Castings for General Industrial Use

ABSTRACT
This specification covers the standard common requirements for iron castings to be used for general industrial applications. The castings shall be made in a workman-like manner and shall conform to the dimensions on drawings furnished by the purchaser before manufacture is started. A lot shall consist of one of the following: all the metal from a single heating in a batch-type melting furnace; all the metal poured from two or more batch-type melting furnaces into a single ladle or a single casting; or all the metal poured from a continuous melting furnace for a given period of time between changes in charge, processing conditions, or aim-for chemistry, whichever is the shorter period. Specimens shall undergo tension tests and shall conform to the specified tensile strength requirements. Chemical analysis such as spectrographic methods shall be performed to determine the chemical composition which shall be in accordance to the carbon content requirement of the specimen. Visual inspection shall also be done to ensure that the casting surface is free of adhering sand, scale, cracks, and hot tears.
SCOPE
1.1 This specification covers a group of requirements that are mandatory requirements when used in conjunction with the following iron casting specifications issued by ASTM: ASTM Specification2
  A47/A47M A48/A48M A197/A197M A220/A220M A278/A278M A319 A395/A395M A436 A439 A518/A518M A532/A532M A536 A571/A571M A823 A842 A874/A874M A897/A897M  
1.2 This specification also covers a group of supplementary requirements which may be applied to the above specifications as indicated herein. These are provided for use when additional testing or inspection is desired and apply only when specified individually by the purchaser in the order.  
1.3 The requirements of the individual material specification, and this general specification shall prevail in the sequence named.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
