SIST-TS CEN/TS 17756:2023

Overview

SIST-TS CEN/TS 17756:2023 is a technical specification developed by the Slovenian Institute for Standardization (SIST) in alignment with CEN guidelines. This standard outlines the referenced method for the determination of chloride content in organic fertilizers, organo-mineral fertilizers, inorganic fertilizers, and liming materials. It is particularly relevant for products placed on the EU market and classified under Product Function Categories (PFC) 1, 2, and 7, as per Regulation (EU) 2019/1009, provided the blends comprise only EU fertilizing products categorized as PFC 1, PFC 2, and PFC 5.

Compliance with this standard supports manufacturers and distributors in demonstrating that their fertilizing products meet quality and safety regulations concerning chloride content - a key criterion for both regulatory acceptance and agricultural application performance.

Key Topics

• Chloride Content Determination
  The specification references standardized laboratory methods for precisely determining chloride levels. This ensures consistent, repeatable, and comparable results across various fertilizer and liming material types.

• Scope of Application

  • Applies to organic, organo-mineral, and inorganic fertilizers, as well as liming materials.
  • Relevant to products within PFC 1, PFC 2, PFC 7, and applicable blends with PFC 5, based on recent EU regulations.

• Sampling and Sample Preparation

  • Sampling must be performed according to EN 1482-1 and EN 1482-3 to guarantee representativeness.
  • Sample preparation follows EN 1482-2 to maintain integrity and validity for testing.

• Referenced Analytical Methods

  • General method: CEN/TS 17758 for potentiometric titration.
  • For samples without organic material: EN 16195 for chloride determination.

• Reporting
  The chloride mass fraction is expressed in grams per kilogram (g/kg), supporting clear comparison and regulatory reporting.

Applications

Implementing SIST-TS CEN/TS 17756:2023 offers several practical benefits:

• Regulatory Compliance
  Enables producers and laboratories to demonstrate conformity with EU Regulation (EU) 2019/1009 on fertilizing product quality and safety criteria.

• Product Quality Assurance
  Standardizes the process for assessing a critical parameter affecting fertilizer performance, crop tolerance, and soil health.

• Market Access
  Supporting documentation using this standard facilitates market access within the European Union by satisfying harmonized requirements for chloride content testing.

• Environmental and Agricultural Impact
  Reliable measurement of chloride content helps optimize fertilizer usage, avoids excessive chloride accumulation in soils, and supports sustainable agricultural practices.
