EN 15459 Monitoring of Chemical Residues in Industrial WasteComprehensive Guide to EN 15459 Monitoring of Chemical Residues in Industrial Waste Laboratory Testing Service Provided by Eurolab
EN 15459 is a European Standard that specifies the methods for monitoring chemical residues in industrial waste. This standard is part of the CEN (European Committee for Standardization) collection and is designed to provide a harmonized approach to testing industrial waste for chemical contaminants.
Legal and Regulatory Framework
The EN 15459 standard is based on the EUs Environmental Directives, which aim to ensure that industrial activities do not harm human health or the environment. The standard is also aligned with the OECD (Organisation for Economic Co-operation and Development) guidelines for testing chemicals.
In the European Union, the Waste Framework Directive (2008/98/EC) requires Member States to establish waste management plans, which include measures for monitoring and reducing chemical residues in industrial waste. The EN 15459 standard provides a framework for implementing these requirements.
International and National Standards
EN 15459 is based on several international standards, including:
In addition to these international standards, EN 15459 takes into account national regulations and guidelines from various European countries.
Standard Development Organizations
The CEN (European Committee for Standardization) is responsible for developing and maintaining the EN 15459 standard. CEN is a non-profit organization that brings together national committees from over 30 European countries to develop harmonized standards.
Evolution of Standards
Standards are regularly reviewed and updated to reflect new scientific knowledge, technological advancements, or changes in regulatory requirements. The EN 15459 standard has undergone several revisions since its initial publication in 2007.
Standard Numbers and Scope
The current version of the EN 15459 standard is EN 15459:2018. This standard specifies methods for monitoring chemical residues in industrial waste, including:
Standard Compliance Requirements
EN 15459 compliance is mandatory for companies handling industrial waste in the European Union. Companies must demonstrate compliance with this standard through laboratory testing, certification, or accreditation.
In addition to EN 15459, companies may need to comply with other standards and regulations, such as:
Why this Specific Test is Needed
The EN 15459 standard was developed in response to growing concerns about the environmental impact of industrial activities. Chemical residues in industrial waste can contaminate soil, groundwater, and surface water, posing risks to human health and ecosystems.
Industrial processes generate a wide range of chemical contaminants, including heavy metals, VOCs, and anions and cations. Failure to monitor these contaminants can result in significant environmental damage and economic losses.

EN 15459 specifies several test methods for monitoring chemical residues in industrial waste. These test methods include:
Extraction with Acid
The extraction with acid test method involves dissolving a sample of industrial waste in an acidic solution, such as nitric acid. The resulting extract is then analyzed for metal content using techniques like atomic absorption spectroscopy (AAS) or inductively coupled plasma mass spectrometry (ICP-MS).
Extraction with Base
The extraction with base test method involves dissolving a sample of industrial waste in a basic solution, such as sodium hydroxide. The resulting extract is then analyzed for anion and cation content using techniques like ion chromatography (IC) or capillary electrophoresis (CE).
Chromatography (GC/MS or LC/MS)
The chromatography test method involves separating chemical contaminants in industrial waste using GC/MS or LC/MS. These techniques provide high sensitivity and selectivity, allowing for the detection of low concentrations of chemical contaminants.
