• Producers are responsible for ensuring conformance to these specifications.

5. Referenced Documents

Includes references to related ASTM standards, such as:

• ASTM B210 (Drawn Seamless Tubes)

• ASTM B211 (Bars, Rods, and Wires)

• ASTM B241 (Seamless Pipe and Tube)

• ASTM E527 (Numbering System for Metals and Alloys)

6. Material Standards

• Aluminum 6063 and other alloys must conform to chemical composition and mechanical property requirements.

• Strength values, temper classifications, and elongation percentages are defined for all materials.

7. Dimensional Tolerances

• Establishes strict tolerances for dimensions to ensure consistency in production.

• Applies to thickness, width, and other critical measurements.

8. Packaging and Marking

• Guidelines for the identification and packing of aluminum products.

• Ensures safe transportation and clear traceability.
