Chemical analysis of the specifications of the castings

　　1 depends on the requirements of the chemical analysis is different, each of the specifications of the casting products is also different. To determine the specifications, the need to evaluate each of the specifications of the castings.

　　

　　2 should be carried out in accordance with the test method of 59 E sampling. Can use test method E and E 30 351 in spectroscopy for chemical analysis or other methods. If you have any dispute, the relevant chemical composition should use the test method E 351 and E 30.

　　

　　3 casting specimens of after cooling type pencil or the thickness of the cut from the casting samples is about 1/32 of an inch of amount of carbon sheets were analyzed. Graphite losses may be caused due to my empty, so this method is not available.

　　

　　According to the terms of E 29, chemical analysis results should be rounded to the similar unit.

　　

　　5 product analysis may be carried out by the buyer, to analyze all aspects of the material. Deal with typical materials. Such as carbon analysis should take samples should not be more than quarter of casting surface, and shall comply with clause 5.3, size or shape of the casting is not allowed except for sampling. Determine the chemical composition should comply with the provisions of the applicable specification requirements of specification.
