prEN 18298:2026 is a draft European Standard from CEN, published in Slovenia by SIST as oSIST prEN 18298:2026. It specifies analytical methods for determining selected elements and parameters in by-products, thermal oxidation materials and derivates, and recovered high-purity materials when those materials are used as components of fertilizing products. The document is aimed at laboratories, product teams, and conformity assessors who need to verify these component materials against the fertilizing-products framework.
What does oSIST prEN 18298:2026 specify?
oSIST prEN 18298:2026 sets out which test methods are used for specific component materials in fertilizing products and organizes them by material type and measured property. It covers by-products, thermal oxidation materials and derivates, and recovered high-purity materials.
| Annex | What it covers |
|---|---|
| Annex ZA | Relationship between this European Standard and the essential requirements of Regulation (EU) 2019/1009 |
The document is arranged in Clauses 1 to 6, followed by informative Annex ZA and a bibliography. Clause 1 gives the scope, Clause 2 lists the normative references, Clause 3 gives the terms and definitions, Clause 4 covers sampling and sample preparation, Clause 5 covers specific elements, and Clause 6 covers specific parameters.
What are the key requirements of oSIST prEN 18298:2026?
The core content of oSIST prEN 18298:2026 is a set of method references. Rather than prescribing one new laboratory procedure, it tells the reader which existing analytical standards to use for each material and each property.
Sampling and sample preparation
Clause 4 states that sampling and sample preparation are crucial for the validity of the document. It also points readers to the relevant analytical methods in Clauses 5 and 6 for instructions where needed. In practice, this means the test result depends on using a representative sample and following the sample-handling steps linked to the chosen method.
Total elements in by-products
Clause 5 covers five total elements in component materials identified as by-products: iron, zinc, copper, cobalt and manganese. For each of these, the document calls for prEN 17768:2026 and prEN 17770:2026. In practical terms, the workflow is digestion by aqua regia followed by ICP-AES analysis, so laboratories know which method chain to apply when checking elemental content.
Dry matter content
Clause 6.1 applies to by-products, thermal oxidation materials and derivates, and recovered high-purity materials. The dry matter content is determined in accordance with prEN 17773:2026. This matters because dry matter is a basic quality parameter for material consistency, dosing, and comparison between batches.
Total organic carbon
Clause 6.2 applies to by-products and recovered high-purity materials. The total organic carbon content is determined in accordance with prEN 17776:2026. In practice, this gives a common way to verify organic-carbon-related requirements for materials that will be used in fertilizing products.
Link to EU fertilising-product conformity
Annex ZA links the standard to Regulation (EU) 2019/1009, especially the CMC provisions for by-products, thermal oxidation materials or derivates, and recovered high-purity materials. For users, this is the part that connects laboratory results to the legal framework for making EU fertilising products available on the market.
What terms does oSIST prEN 18298:2026 define?
- By-products - materials treated in the document as component materials for fertilizing products, linked in the introduction to CMC 11.
- Thermal oxidation materials and derivates - component materials covered by the dry matter requirement in Clause 6.1, linked to CMC 13.
- Recovered high-purity materials - component materials covered by dry matter and total organic carbon requirements, linked to CMC 15.
- Dry matter content - the non-water portion of the material, measured here as a quality parameter for several component materials.
- Total organic carbon (TOC) - the total carbon associated with organic matter, determined by the dry-combustion method named in Clause 6.2.
- CMC - component material category under Regulation (EU) 2019/1009; the document uses CMC 11, CMC 13 and CMC 15.
- ICP-AES - the instrumental technique named in the cited element-determination method for measuring total elemental content after digestion.
Who uses oSIST prEN 18298:2026?
oSIST prEN 18298:2026 is used by laboratories that test fertilizing-product component materials, and by quality or technical teams that need to specify or check test methods for those materials. It is also relevant to conformity assessment and regulatory work because Annex ZA ties the methods to the essential requirements of Regulation (EU) 2019/1009. In practice, users rely on it when deciding which method to apply for elemental content, dry matter, or total organic carbon in the relevant CMCs.

Introduction
An EU fertilizing product consists solely of component materials complying with the requirements for
one or more of the component material categories (CMCs), as specified in the Regulation (EU) 2019/1009
[1]. This regulation lays down the rules on the making available on the market of EU fertilizing products
and the specific safety and quality requirements for the CMCs.
By-products within the meaning of Directive 2008/98/EC have been classified as CMC 11, thermal
oxidation materials or derivates as CMC 13 and recovered high purity materials as CMC 15, in Regulation
(EU) 2019/1009 [1].
In this document the normative references of the test methods to be used for these CMCs are defined in
order to measure the compliance with the related requirement in the Regulation (EU) 2019/1009 [1].
