Overview
EN 14397-2:2004 (CEN) specifies a standardized laboratory method for the determination of carbon dioxide (CO2) in liming materials. It is Part 2 of the EN 14397 series and applies to all liming materials used in agriculture and soil improvement. The method is a volumetric liberation/absorption technique in which CO2 from carbonates is released by hydrochloric acid, measured as a gas volume and quantified after calibration.
Key topics and technical requirements
- Scope: Determination of CO2 content in all liming materials (European Standard approved by CEN).
- Principle: CO2 in carbonates is liberated by reaction with HCl and measured volumetrically; the CO2 volume absorbed in KOH gives the CO2 content.
- Reagents: Concentrated and diluted HCl, concentrated H2SO4, Na2SO4, ethanol, methyl red indicator, KOH solution, CuSO4 and pre-dried CaCO3 for calibration.
- Apparatus: Decomposition flask, dropping funnel, measuring burette, absorption vessel (KOH), levelling bottle with sealing liquid, heating device and precision balance (0.0001 g).
- Test portion guidance: Sample mass depends on expected CO2 mass fraction (table provided in the standard; e.g., 0.1 g for >15% CO2, up to 2 g for ≤2%).
- Calibration & calculation: Apparatus is calibrated using pre-dried CaCO3; results are calculated from volume differences (V1 − V2), corrected by a factor F1 that accounts for temperature and pressure. Simplified equations apply when calibration and measurement are consecutive.
- Precision: Repeatability and reproducibility expressed as functions of wCO2:
- sr = 0.065 · wCO2
- sR = 0.09 · wCO2
- Reporting: Test report must identify the sample, reference the standard, present results and units, and note any deviations or observations.
Applications and users
- Who uses it: Analytical laboratories, fertilizer and lime manufacturers, quality control teams, regulatory bodies, and research institutions involved in soil amendment products.
- Practical value:
- Ensures consistent, comparable CO2 determinations for product specifications and labeling.
- Supports compliance with national and EU regulations for liming materials.
- Provides a validated procedure for quality control (QC) and R&D of lime-based soil amendments.
- Useful for certification, trade disputes, and product formulation where carbonate content and neutralizing value matter.
