Overview

CEN/TS 17756:2022 specifies the references to validated methods for the determination of the chloride content in organic fertilizers, organo-mineral fertilizers, inorganic fertilizers and liming materials. The Technical Specification supports conformity assessment with Regulation (EU) 2019/1009 by identifying appropriate test references and defining the expression of results (mass fraction of chlorides expressed in g/kg).

This document is applicable to EU fertilizing products classified as PFC 1, PFC 2 and PFC 7, subject to the blending constraints referenced in the Regulation. It is intended for laboratories, manufacturers, conformity assessors and national standardization bodies involved in fertilizer quality and safety testing.

Key Topics

• Scope and applicability: Defines which product function categories (PFCs) and blends the chloride determination references apply to.
• Referenced test methods: Points to specific normative documents for sampling, sample preparation and analytical determination:
  • EN 1482-1/2/3 for sampling and sample preparation
  • CEN/TS 17758:2022 for chloride determination by potentiometric titration
  • EN 16195:2012 for chloride determination in inorganic materials where organic matter is absent
• Result expression: Chloride mass fraction reported as g/kg (wCl).
• Sampling requirements: Samples for quality control must be representative and prepared according to the referenced EN sampling standards.

Keywords: chloride content, fertilizers, liming materials, sampling, sample preparation, potentiometric titration, CEN/TS 17756:2022.

Applications

CEN/TS 17756:2022 is practical for stakeholders who need consistent, reproducible chloride measurements to demonstrate product compliance, inform product formulation, and manage agronomic or environmental impacts. Typical applications include:

• Regulatory compliance testing of EU fertilizing products under Regulation (EU) 2019/1009
• Routine quality-control analysis in fertilizer production and blending facilities
• Laboratory method selection and method referencing for accreditation and reporting
• Comparative assessment of chloride levels across product batches or suppliers

Using the referenced sampling standards (EN 1482 series) ensures representative test portions, while CEN/TS 17758:2022 and EN 16195:2012 provide the analytical references appropriate for materials with or without organic content.

Related Standards

• EN 1482-1:2007 - Sampling
• EN 1482-2:2007 - Sample preparation
• EN 1482-3:2016 - Sampling of static heaps
• CEN/TS 17758:2022 - Determination of chloride content by potentiometric titration
• EN 16195:2012 - Determination of chlorides in absence of organic material
• Regulation (EU) 2019/1009 - Market rules and PFC classifications

For laboratories and manufacturers, following CEN/TS 17756:2022 and its normative references ensures clarity on method selection, consistent reporting (g/kg), and alignment with European regulatory requirements for fertilizer quality and safety.

This Technical Specification (CEN/TS) was approved by CEN on 13 March 2022 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
