ASTM B85 / B85M – 18e1 Standard Specification for Aluminum-Alloy Die Castings

Die castings inspected by this method shall be so marked or handled during the? This abstract is a brief summary of the referenced standard. Referenced Documents purchase separately The sstm listed below are referenced within the subject standard but are not provided as part of the astn. Link to Active This link will always route to the current Active version of the standard. Rejection and Retest The applicable levels shall be as speci? This specification covers aluminum-alloy die castings of all compositions.

Die castings of alloys A 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 b885 conform to the chemical requirements prior to pouring any aetm.

For this reason, b8 is considered that the only practical method for mechanical property control is proof testing the whole die casting. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

In case of dispute, the methods of analysis shall be agreed upon between the producer and the purchaser.

If the producer has determined the chemical composition of the metal during the course of manufacture, he shall not be required to sample and analyze the? The castings shall be supplied such that they can be laid out and machined to the final dimensions specified on the blueprints or drawings.

When tension or impact tests are made, the tension test specimen shown in Fig. Originally approved in 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.

B For purposes of acceptance and rejection, the observed value or calculated value obtained from analysis should be rounded off to the nearest unit in the last right-hand place qstm

All tests and inspection shall be so conducted as not to interfere unnecessarily with the operation of the works. The producer or supplier may use a system of statistical quality control for such examinations. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. C Limits are in percent maximum unless shown otherwise. The marking shall consist of raised Arabic numerals, and when applicable capital letters, cast integral.

Die castings asmt not generally gas or arc welded or brazed. Combining values from the two systems may asym in non-conformance with the standard.

Additions of small amounts of modifiers and grain refining elements or alloys are permitted.
