Standard Specification for Modern Pewter Alloys — 4 стр.
Реферат

This specification covers three modern alloy types, made from tin, antimony, and copper, used in the fabrication of pewter articles by casting, spinning, drawing, or forming. These alloy types include: castings (Type I), sheets (Type 2), and special-purpose alloys (Type 3). The metal may be supplied in the form of bar, ingot, rolled sheet, and circle, all of which shall be available in the specified nominal dimensions (thickness, width, length, and/or diameter) and mass. Pewter alloy shall be defined as having a composition within the prescribed range for tin, antimony, and copper, and shall conform to the specified impurity limits for lead, arsenic, iron, and zinc.

Область применения

1.1 This specification covers three Pewter alloy types as shown in Table 1, made from tin, antimony, and copper, used in the production and fabrication of finished or semi-finished pewter products by casting, spinning, drawing, or forming. The metal may be supplied in the form of bars, ingots, rolled sheet, and circles.

1.2 Pewter alloy shall be defined as having a composition within the range from 90 to 98 % tin, 1 to 8 % antimony, and 0.25 to 3 % copper. Compositions are given in Table 1.

1.3 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.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
