Overview

EN 604-2:1997 is a European standard developed by CEN, titled "Aluminium and aluminium alloys - Cast forging stock - Part 2: Tolerances on dimensions and form." This standard defines the acceptable tolerances for dimensions and form of cast aluminium and aluminium alloy forging stock tailored for general engineering applications. It complements related standards such as EN 573-3, which specifies the chemical compositions of these alloys, and EN 604-1, which addresses technical conditions for inspection and delivery. The application of EN 604-2 ensures consistent quality and compatibility of aluminium cast forging stock in manufacturing processes.

Key Topics

• Scope of Tolerances
  EN 604-2 outlines the permissible deviations in dimensions and geometric form of cast aluminium and aluminium alloy forging stock, ensuring components meet rigorous engineering requirements.

• Material Coverage
  The standard applies to a variety of aluminium alloys used in casting and forging, with specific chemical compositions referenced from EN 573-3.

• Dimensional Precision
  It specifies precise limits for length, width, height, and other critical measurements to maintain uniformity across production batches.

• Form Tolerances
  Guidelines include tolerances on aspects such as flatness, straightness, roundness, and cylindricity to guarantee the functional integrity of forged components.

• Inspection and Delivery
  Integrated with EN 604-1, EN 604-2 establishes a framework for inspection procedures and criteria for acceptance or rejection of casting stock during delivery.

Applications

• General Engineering
  This standard is essential for industries utilizing cast aluminium forging stock in the manufacturing of mechanical parts, structural components, and tools.

• Automotive and Aerospace
  Precise tolerances facilitate the production of lightweight, high-strength components crucial for vehicle and aircraft manufacturing.

• Machinery and Equipment Production
  Ensures that forging stock meets strict form and size requirements, simplifying downstream machining and assembly processes.

• Quality Assurance and Supply Chain
  EN 604-2 provides manufacturers and suppliers with a common reference to guarantee dimensional and form consistency, minimizing production errors and enhancing cooperation.

Related Standards

• EN 573-3: Specifies the chemical compositions of aluminium and aluminium alloys used in cast forging stock. It ensures material conformity alongside dimensional control.

• EN 604-1: Defines the technical conditions for inspection and delivery of aluminium and aluminium alloy cast forging stock, complementing the dimensional tolerances in EN 604-2.

• EN 15088: Covers wrought aluminium and aluminium alloy forgings, which may be referenced for related forged components outside casting stock scope.

• ISO 9385: International counterpart detailing dimensions and tolerances for aluminium alloy forgings may be consulted for global projects or additional guidelines.

Summary

EN 604-2:1997 serves as a critical standard for maintaining dimensional and form quality in cast aluminium and aluminium alloy forging stock. By adhering to these tolerances, manufacturers benefit from improved product reliability, enhanced machinability, and alignment with international quality expectations. This standard is indispensable for engineering sectors seeking consistent, high-quality aluminium forgings for a wide array of industrial applications.
