SIST EN 13920-15:2004

SIST EN 13920-15:2004 is the Slovenian adoption of EN 13920-15:2003, published by SIST. It covers decoated aluminium scrap from post-consumer aluminium packagings and tells suppliers, purchasers, and recyclers how to describe, assess, and accept that material. The standard specifies the required characteristics, chemical composition, and metal yield for this scrap category.

What does SIST EN 13920-15:2004 specify?

SIST EN 13920-15:2004 specifies the requirements for decoated aluminium scrap obtained from mixed used aluminium packagings, including scrap produced by pyrolysis, mechanical delamination, chemical delamination, or a combination of these processes. It also applies to aluminium scrap separated from the bottom ashes of incinerators.

The document is organized into six clauses:

• Scope
• Normative references
• Terms and definitions
• Ordering information
• Requirements
• Classification procedure, treatment of non-conformities and arbitration

For a buyer or recycler, this structure shows where to find the product description, how to place an order, and what the delivered scrap must meet.

What are the key requirements of SIST EN 13920-15:2004?

SIST EN 13920-15:2004 builds on EN 13920-1 and then adds scrap-specific conditions for this product category. The practical focus is on contamination control, composition after melting, and a measurable metal yield.

General condition and conformity

Clause 5.1 requires the scrap to meet the general requirements of EN 13920-1 together with the additional requirements in this part. If the scrap does not fully match those requirements, the supplier must tell the purchaser about the deviation and obtain agreement before shipment. In practice, this means deviations cannot be left implicit in delivery paperwork.

Physical characteristics

Clause 5.2 requires the scrap to be free of free iron, not heavily oxidized by the decoating process, and free from fine particles below the specified size limit and from non-metallic foreign materials. For users, this matters because iron, oxidation, fines, and foreign matter can affect melting behavior, yield, and downstream alloy quality.

Chemical composition

Clause 5.3 sets the chemical composition for the scrap after magnetic removal of free iron and appropriate melting. The composition is controlled by limits on the main residual and alloying elements, with aluminium as the balance. In practice, this is the check that tells a remelter whether the material can be used as a recycling feedstock without unexpected chemistry problems.

Metal yield

Clause 5.4 requires the metal yield, determined in accordance with EN 13920-1 and related to the mass in the as-delivered condition, to meet the standard’s minimum level. The note adds that different decoating processes can lead to different yield values. For operations, this links the scrap category to recovery performance and helps compare offers from different suppliers or processes.

Ordering and acceptance

Clause 4 requires the order to state the standard number, the scrap category, the gross mass of the consignment, the delivery period, and any characteristics that differ from the stated requirements. It can also include origin, size, and surface condition information. This helps the buyer and supplier align on exactly what is being delivered before the material arrives.

Classification, non-conformities, and arbitration

Clause 6 sends classification, sampling, tests, non-conformity handling, and arbitration back to EN 13920-1. That gives a single framework for disputes and acceptance checks across the EN 13920 scrap series.

What terms does SIST EN 13920-15:2004 use?

Key terms used in SIST EN 13920-15:2004 include:

• Decoated aluminium scrap - aluminium scrap from which surface coatings have been removed before recycling.
• Post-consumer aluminium packagings - used aluminium packaging material collected after consumer use.
• Scrap - aluminium material intended as raw material for recycling.
• Metal yield - the amount of recoverable metal obtained from the delivered scrap after the defined assessment.
• Free iron - iron contamination that is not part of the aluminium scrap itself and must be removed.
• Fines - very small particles of scrap that are not acceptable under the product requirements.
• Non-metallic foreign materials - unwanted non-metallic contamination mixed with the scrap.

Who uses SIST EN 13920-15:2004?

SIST EN 13920-15:2004 is used by scrap suppliers, recyclers, remelters, purchasers, and quality staff who need a common description for decoated aluminium scrap. It is relevant for anyone arranging delivery, checking acceptance, testing composition, or documenting conformity of scrap from used aluminium packagings. It also helps when scrap comes from incinerator bottom ashes and needs to be classified for recycling.

What changed in SIST EN 13920-15:2004 from the previous edition?

SIST EN 13920-15:2004 is the Slovenian identical adoption of EN 13920-15:2003.

Which standards are used with SIST EN 13920-15:2004?

SIST EN 13920-15:2004 refers to two companion documents:

• prEN 12258-3:2000 - provides the terms and definitions for aluminium and aluminium alloy scrap.
• EN 13920-1:2003 - provides the general requirements, sampling and tests, and the procedure for classification, non-conformities, and arbitration.

These references are important because they supply the shared vocabulary and the common acceptance method for the EN 13920 scrap series.

What does the SIST EN 13920-15:2004 document contain?

SIST EN 13920-15:2004 contains the order information needed to specify a shipment, the product characteristics that control contamination and surface condition, and the chemical composition table for the scrap after magnetic removal of free iron and melting. It also gives the metal yield requirement and points users to EN 13920-1 for sampling, tests, classification, and dispute handling. The document is therefore both a product description and an acceptance framework for recycled aluminium feedstock.
