5、fication A1025, this specification shall prevail.4. Chemical Requirements4.1 The material shall conform to the requirements as tochemical composition specified in Table 1 and Table 2. Themanufacturer shall furnish an analysis of each shipmentshowing the percentage of each element specified in Table
6、1.4.2 For the elements specified in Table 2 an analysis of eachlot is not required. Upon request of the purchaser the manu-facturer shall supply the results of an analysis for the elementsin Table 2 on a cumulative basis over a period mutually agreedupon by the manufacturer and the purchaser.5. Size
7、5.1 Calcium-silicon alloys are available in sizes as listed inTable 3.5.2 The sizes listed in Table 3 are typical as shipped fromthe manufacturers plant. These alloys are friable and someattrition can be expected in transit, storage, and handling. Thefriability rating for these alloys is Code No. 6,
8、 the most friablerating on the scale.6. Sampling6.1 Methods of sampling may be agreed upon by themanufacturer and the purchaser.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.18 on Ca
