I know that in the aeronautical industrie , aluminiun piece are annealed , and to keep it in such state , it shall be kept at low temperature , about -40ºC or ºF for no more than 3 days.
I want know which standard cover it , no mater if it is ASTM , or from Europe or from any place.
Thanks in advance

This was my first hit on Google: ASTM Standards
B26/B26M Specification for Aluminum-Alloy Sand Castings
B108 Specification for Aluminum-Alloy Permanent Mold Castings
B275 Practice for Codification of Certain Nonferrous Metals and Alloys, Cast and Wrought
B557 Test Methods for Tension Testing Wrought and Cast Aluminum- and Magnesium-Alloy Products
B557M Test Methods for Tension Testing Wrought and Cast Aluminum- and Magnesium-Alloy Products (Metric)
B618 Specification for Aluminum-Alloy Investment Castings
B686 Specification for Aluminum Alloy Castings, High-Strength
B881 Terminology Relating to Aluminum- and Magnesium-Alloy Products
B918 Practice for Heat Treatment of Wrought Aluminum Alloys G110 Practice for Evaluating Intergranular Corrosion Resistance of Heat Treatable Aluminum Alloys by Immersion in Sodium Chloride + Hydrogen

It should be noted that if an aluminum alloy has been truly annealed, it is not required to refrigerate the metal to keep it soft.
Keeping the metal cold is used for heat treated alloys that soften when heated and quenched then get harder later.
This is known as the AQ or W temper.

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor
