4.1 The purpose of these color codes is to allow for quick identification of ingot bundles or jumbo ingots of zinc casting alloys. Other than jumbo ingots, this standard is not intended to imply that each ingot will be color coded but only that each ingot bundle be color coded.
4.2 Each ingot bundle or jumbo ingot shall be identified with the appropriate color code listed in Table 1.
(A) UNS assignations were established in accordance with Practice E527. The last digit of a UNS number differentiates between alloys of similar composition.(B) The North American system is design to be a simplified version of the International system by eliminating the leading white stripe and in the case of Alloy 3 eliminating all stripes.(C) ASTM alloy designations established in accordance with Practice B275.(D) The color codes for these alloys are adapted from European standard (CEN) specification EN 1774. No color coding currently exists in International standard ISO 301.(E) These alloys are not currently included in European standard EN 1774 nor International standard ISO 301 and no color codes have previously been assigned.(F) ACuZinc
4.3 The color will be applied as a stripe, or stripes, near the corners on opposite ends of two adjacent sides of the ingot bundle or jumbo ingot. The color stripes will be applied to include the ingot bundle foot.
4.4 When using multiple stripes, the colored stripes will be applied from left to right as indicated in Table 1.
4.5 In the absence of a written agreement to the contrary between the supplier and end user, the North American color code will be the standard for all North American transactions; for all other transactions the International Color Code will be used.View Less
1.1 This standard is published with the following objectives:
1.2 To establish standard color codes for the Zinc Die Casting and Foundry industry, and
1.3 To standardize the use and application of these color codes.
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 Safety Data Sheet (SDS) 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.
