1. separate cast test sample A test sample casted per each batch by using a sand mold separated from iron castings.
2. cast-on test sample A test sample casted by sticking the same kind casting mold as iron casting to a specified position of the casting main body.
3. The letter "A" suffixed to the symbol of grade indicates that the properties are obtained on cast-on test sample.
