This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. General Conditions for Delivery
3.1 Material furnished to this specification shall conform to the requirements of Specification A 1025, including any
supplementary requirements that are indicated in the purchase order. Failure to comply with the general requirements of
Specification A 1025 constitutes nonconformance with this specification. In case of conflict between the requirements of this
specification and Specification A 1025, this specification shall prevail.
4. Chemical Requirements
4.1 The material shall conform to the requirements as to chemical composition specified in Table 1 and Table 2. The
manufacturer shall furnish an analysis of each shipment showing the percentage of each element specified in Table 1.
4.2 For the elements specified in Table 2 an analysis of each lot is not required. Upon request of the purchaser the manufacturer
shall supply the results of an analysis for the elements in Table 2 on a cumulative basis over a period mutually agreed upon by
the manufacturer and the purchaser.
5. Size
5.1 Calcium-silicon alloys are available in sizes as listed in Table 3.
5.2 The sizes listed in Table 3 are typical as shipped from the manufacturer’s plant. These alloys are friable and some attrition
can be expected in transit, storage, and handling. The friability rating for these alloys is Code No. 6, the most friable rating on the
scale.
6. Sampling
6.1 Methods of sampling may be agreed upon by the manufacturer and the purchaser.
