Overview - EN 16199:2012 (Fertilizers / Sodium by flame-emission)

EN 16199:2012 is a CEN European Standard that specifies a laboratory method for the determination of sodium extracted from fertilizer samples by flame‑emission spectrometry. The procedure applies to EC fertilizers for which sodium content must be declared under Regulation (EC) No 2003/2003, Annex I. The method uses extracts prepared according to EN 15960 or EN 15961 and measures sodium emission at the sodium D‑line (589.3 nm).

Key topics and technical requirements

  • Analytical principle: Flame‑emission spectrometry of diluted fertilizer extracts, after extraction per EN 15960 (total) or EN 15961 (water soluble).
  • Sampling / sample prep: Sampling itself is outside the method but EN 1482 series is referenced for sampling and EN 1482-2 for sample preparation and grinding to homogeneity.
  • Reagents and standards: Includes diluted HCl, aluminium nitrate, caesium chloride (CsCl), anhydrous NaCl and a 1 mg/ml sodium standard. A CsCl/Al(NO3)3 matrix modifier solution and a series of calibration solutions (0–10 µg/ml Na) are specified.
  • Apparatus: A flame‑emission spectrometer set at 589.3 nm and calibrated glassware (100, 250, 1 000 ml flasks).
  • Procedure: Prepare appropriate intermediate and final dilutions (tables provided) depending on expected Na content, add Cs/Al modifier, calibrate instrument with prepared standards, measure samples in triplicate.
  • Calculations: Sodium mass fraction (wNa) and converted Na2O content (wNa2O) calculated using the measured concentration and dilution factors; conversion factor Na → Na2O (1.348) is given.
  • Precision and validation: Precision assessed in inter‑laboratory studies (2007, 2009) with repeatability (r) and reproducibility (R) limits calculated per ISO 5725‑2; reported r and R depend on sample matrix and concentration.

Applications and who uses it

  • Laboratories performing routine fertilizer quality control and compliance testing.
  • Manufacturers and quality assurance teams verifying declared sodium content on EC fertilizers.
  • Regulatory bodies and notified laboratories enforcing Regulation (EC) No 2003/2003 labeling and composition rules.
  • Research labs comparing extraction methods (EN 15960 vs EN 15961) for sodium analysis.

Practical value / benefits

  • Provides a standardized, reproducible method for accurate sodium quantification in fertilizer extracts.
  • Enables industry and regulators to compare results across labs using established repeatability and reproducibility criteria.
  • Supports compliance with EU fertilizer declaration requirements and product labeling.

Related standards

  • EN 15960, EN 15961 (extraction procedures)
  • EN 1482‑1 / EN 1482‑2 (sampling and sample preparation)
