Subsequent to the publication of this frestandard, the technical content shall not be changed to an extent that interchangeabilify is affected, physically or functionally, without re-identification of the standard. After examination and re
5、view by users and formal agreement of AECMA-STAN, it will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardization) for formal vote and transformation to full European Standard (EN). The CEN national members have then to implement the EN at national level by gi

Unless otherwise advised by the purchaser, the manufacturer may, at his discretion, and especially to minimize distortion in thin sections, alternatively air cool to ambient temperature from the solution heat treatment temperature or use water with quench additives (polymer quench) at 6% 30 OC. The tensile properties stated may not be consistently achievable in all parts of all castings. Any differing requirements stated on the drawing shall take precedence over those of this material standard. b 100 Page 6 prEN 461 5:2004 - Product qualification
