This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Comparison between static breakdown or proof tests and the mechanical properties of separately die cast test bars will show that test bars made in a different machine in a different die have no correlation with the die casting other than a common chemical TABLE X2.

No one alloy is best in all categories. Rejection and Astn Marking for shipment shall be in accordance with Fed. Generally aluminum die castings b5 unsuitable for light color anodizing where pleasing appearance is required. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. G Based on resistance of alloy in standard type salt spray test.

Pure materials, recycled materials, and master alloys and material not conforming to Specification B may be used to make alloys conforming to this specification, provided chemical analysis can be taken and adjusted to conform to the chemical requirements prior to pouring any castings. The characteristics are rated from 1 to 51 being the best and 5 being the least desirable for that attribute.
