SIST EN 577:1998

Overview

EN 577:1995 - Aluminium and aluminium alloys - Liquid metal - Specifications is a CEN (European) standard that specifies the requirements for the delivery of unalloyed aluminium and aluminium alloys in the form of liquid metal. The standard is intended to ensure consistent quality, documentation and handling practices for molten aluminium supplied between producers, transporters and users. (Note: this standard is adopted identically in some national collections, e.g. SIST EN 577:1998.)

Key Topics

The standard defines requirements and expectations around the delivery of liquid aluminium and aluminium alloys. Key technical topics covered include:

• Scope and definitions relevant to liquid metal deliveries and terminology for aluminium alloys.
• Quality and condition of the molten metal on delivery, including cleanliness and acceptable contamination limits.
• Composition and conformity - expectations for alloy identification and conformity to agreed chemical composition (tolerances and verification procedures are specified or referenced).
• Temperature and physical condition at the point of transfer to ensure safe handling and process compatibility.
• Sampling and testing procedures for verifying the molten metal’s composition and quality prior to acceptance.
• Marking, documentation and certification accompanying liquid metal consignments (records, certificates of analysis, batch identification).
• Packaging, transport and transfer arrangements to maintain metal integrity and traceability during delivery.
• Safety and handling considerations during loading, transport and receipt of liquid aluminium.

(EN 577 focuses on delivery requirements rather than detailed metallurgical processing methods; it may reference or be used alongside testing and product standards.)

Applications

EN 577 is used wherever molten aluminium is bought, sold, or transferred, including:

• Primary aluminium producers and remelters who supply liquid metal.
• Foundries and diecasters receiving molten aluminium for casting operations.
• Industrial alloy producers and integrated metalworks managing alloy charging.
• Procurement, quality assurance and inspection teams who verify incoming liquid metal quality.
• Logistics and transport providers specializing in molten metal transfer.

Using the standard helps reduce supply disputes, ensures repeatable quality for casting processes, and supports traceability and regulatory compliance.

Related standards

EN 577 is part of the family of European standards addressing aluminium products, testing and alloy specifications. For complete conformity, users typically apply EN 577 alongside relevant EN/CEN standards on aluminium chemical analysis, product specifications and testing methods, and consult any national adoptions (e.g., SIST EN 577:1998).
