Overview
EN 238:1996/A1:2003 (CEN) specifies the use of infrared spectrometry for the determination of benzene content in petrol. This amendment updates precision data, with particular emphasis on benzene levels around 1% and below, as reported by WG 9 (doc. N 1108). The standard supports consistent laboratory measurement, improved analytical reliability, and harmonised fuel quality assessment across member states.
Key Topics
- Scope and purpose: Determination of benzene in liquid petroleum products (petrol) using infrared spectrometric techniques.
- Updated precision data: Focus on precision and repeatability at benzene concentrations around 1% and below, reflecting the WG 9 report.
- Methodology context: The standard defines procedural requirements for IR spectrometry as the analytical technique for benzene quantification (method details are contained in the normative text).
- Standard adoption: EN 238:1996/A1:2003 has been adopted nationally (e.g., SIST EN 238:1998/A1:2004) to ensure uniform application.
Keywords: benzene content, petrol, infrared spectrometry, EN 238, precision data, fuel quality, petrol analysis.
Applications
The standard is directly applicable to laboratories and organisations involved in fuel testing and compliance:
- Quality control laboratories: Routine monitoring of benzene content in petrol to ensure product consistency and safety.
- Regulatory compliance: Supporting conformity assessment with national and regional fuel regulations where benzene limits are specified.
- Production monitoring: Refiners and fuel producers can use the method to track benzene during blending and processing.
- Inter-laboratory comparison: Provides a harmonised basis for proficiency testing and method validation when assessing low benzene levels.
Benefits include improved measurement confidence at low benzene concentrations, better comparability between laboratories, and clearer guidance for method implementation and interpretation of results.
Related Standards
- National adoptions of EN 238:1996/A1:2003 (for example, SIST EN 238:1998/A1:2004) reflect local publication and use.
- Other CEN standards and technical reports on fuel analysis and hydrocarbon determination may complement EN 238 where broader test suites are required.
For practitioners, EN 238:1996/A1:2003 is a practical reference for laboratories performing benzene determinations by IR spectrometry, especially when precise, low-level measurements are required. Consult the full normative text for detailed procedural requirements, calibration, and reporting conventions.
