Significance and Use4.1 The purpose of these color codes is to allow for quickidentification of ingot bundles or jumbo ingots of zinc castingalloys. Other than jumbo ing
9、ots, this standard is not intended toimply that each ingot will be color-coded but only that eachingot bundle be color coded.4.2 Each ingot bundle or jumbo ingot shall be identifiedwith the appropriate color code listed in Table 1.4.3 The color will be applied as a stripe, or stripes, on twoadjacent
10、 sides of the ingot bundle or jumbo ingot. The colorstripes will be applied to include the ingot bundle foot.4.4 When using multiple stripes, the colored stripes will beapplied from left to right as indicated in Table 1.4.5 In the absence of a written agreement to the contrarybetween the supplier an
11、d end user, the North American colorcode will be the standard for all North American transactions;for all other transactions the International Color Code will beused.5.
