SIST EN 13920-3:2004

Overview

SIST EN 13920-3:2004 is a European Standard focused on the classification and specification of aluminium and aluminium alloy scrap, specifically wire and cable scrap. Developed by the Slovenian Institute for Standardization (SIST) in accordance with CEN (European Committee for Standardization), this document addresses both new and old scrap derived from unalloyed aluminium with a composition of at least 99.5% aluminium, as well as defined aluminium alloys. The standard ensures reliable quality and enhances the value of aluminium recycling by defining characteristics, composition, and yield requirements for wire and cable scrap.

Key Topics

• Definition of Wire and Cable Scrap:
  Covers both new scrap (from manufacturing) and old scrap (from dismantled electrical lines) in the form of aluminium wires or cables.

• Material Requirements:

  • Scrap must come from aluminium wires with a minimum diameter of 0.8 mm.
  • Only uncoated wires free from attachment devices, steel cores, plastics, and other foreign materials are accepted.
  • Scrap must have undergone volume reduction processes such as baling, coiling, or shredding unless otherwise agreed.

• Chemical Composition:

  • Unalloyed aluminium scrap must contain not less than 99.5% aluminium.
  • Alloyed wire and cable scrap, such as those from the 6xxx series, must meet defined composition limits.
  • Compliance with EN 13920-1 and EN 1715-1 for inspection and conformity.

• Metal Yield:

  • Scrap must provide a minimum metal yield of 95% as measured after processing and melting.

• Ordering and Traceability:

  • Specifies necessary information for orders, including standard reference, scrap category, mass, delivery period, and any deviations or origin details.

Applications

SIST EN 13920-3:2004 is vital in several sectors leveraging aluminium recycling for environmental and economic benefits:

• Metal Recycling Industry:
  Serves as a reference for purchasing, processing, and sorting aluminium wire and cable scrap, ensuring compliance with set quality standards.

• Electrical and Power Sector:
  Outlines the procedure for recycling used aluminium powerlines, supporting sustainability targets for utility companies and contractors involved in line decommissioning.

• Manufacturing:
  Streamlines the management of new manufacturing offcuts and waste, enabling alloy producers and smelters to maintain consistent input quality.

• Regulatory Compliance:
  Assists organizations in fulfilling European regulatory requirements for waste management, traceability, and sustainable resources use.

Related Standards

To implement the requirements of SIST EN 13920-3:2004 effectively, the following related standards should be considered:

• EN 13920-1: Aluminium and aluminium alloys - Scrap - Part 1: General requirements, sampling, and tests.
• EN 1715-1: Aluminium and aluminium alloys - Drawing stock - Part 1: General requirements and technical conditions for inspection and delivery.
• prEN 12258-3: Aluminium and aluminium alloys - Terms and definitions - Part 3: Scrap.

For comprehensive scrap management and recycling processes, other parts of the EN 13920 series address various forms and sources of aluminium scrap, such as castings, beverage cans, and post-consumer packaging.

By adhering to SIST EN 13920-3:2004, organizations can ensure consistent quality in aluminium scrap, enhance the efficiency of recycling operations, and contribute to a sustainable resource cycle. This standard is instrumental for achieving high-quality secondary aluminium production and supports traceable, responsible recycling practices in Europe.
