Overview
EN 1744-8:2012 is a European standard developed by CEN that specifies a standardized method for determining the metal content in Municipal Incinerator Bottom Ash (MIBA) Aggregates. The standard outlines a sorting test designed to estimate the relative proportions of metallic constituents, such as ferrous and non-ferrous metals, within MIBA aggregates. This method provides a reference approach for type testing and resolving disputes related to metal content measurement. It also supports factory production control when calibrated against the reference procedure.
This standard is essential for professionals involved in recycling, waste management, aggregate testing, and quality control within the construction and environmental industries. The method ensures consistent, accurate estimation of metal fractions, which is critical for optimizing recycling processes and assessing the suitability of MIBA aggregates for various applications.
Key Topics
Scope and Purpose
EN 1744-8:2012 defines a simple, hand-sorting procedure that separates metallic particles in MIBA aggregates into ferrous (magnetic) and non-ferrous (non-magnetic) categories by mass percentage. It also describes a supplementary crushing and sieving method for agglomerated particles to provide more accurate metal content estimation.Sampling and Sample Preparation
- Bulk MIBA samples are reduced to laboratory samples following EN 932 series standards.
- Samples are dried to a constant mass at 110 ± 5 °C and sieved to remove overly large or fine particles.
- Subsamples are further reduced to contain a representative minimum number of particles (usually at least 1,000).
Sorting and Analysis Procedure
- The dried subsample is divided into size fractions (4–16 mm, 16–32 mm, 32–63 mm).
- Metallic particles are manually identified and separated.
- A magnet is used to distinguish ferrous from non-ferrous particles.
- Weighing allows calculation of the percentage of each metallic fraction relative to the total subsample mass.
Calculation and Reporting
- Percentages are calculated by dividing the mass of metallic particles by the mass of the prepared subsample.
- Test reports include sample identification, masses of fractions, and calculated metal proportions.
- Optional details can include particle size distribution and specifics of the sample reduction process.
Supplementary Method (Annex A)
A supplementary procedure involves crushing and sieving agglomerated particles to improve metal separation efficiency when complete separation is difficult.Apparatus Requirements
Specific test sieves, handsorting tools, a laboratory crusher, and a high-strength handheld magnet (pull strength ≥ 60 kg) are among the required equipment.
Applications
Environmental Recycling
Accurate assessment of metals like aluminum and iron in MIBA aggregates is vital for recycling initiatives, helping to recover valuable metals and improve resource recovery rates.Quality Control of Construction Materials
MIBA aggregates are increasingly reused in construction applications (e.g., as filler material or road base). Knowing the metal content ensures compliance with regulations and suitability for intended uses.Compliance Testing and Dispute Resolution
The standardized sorting test serves as a reference method for type testing and resolving disputes concerning metal content in MIBA aggregates, providing legally and technically sound results.Factory Production Control
Facilities producing MIBA aggregates can implement this or equivalent validated sorting methods to monitor and control the quality of their output.
