This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 260.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

European foreword
This document (prEN 17816:2026) has been prepared by Technical Committee CEN/TC 260 “Fertilizers
and liming materials” the secretariat of which is held by DIN.
This document is currently submitted to CEN Enquiry.
This document will supersede EN 17816:2023.
— Scope (Clause 1) updated;
— Normative references (Clause 2) updated;
— Sampling and sample preparation (Clause 4) updated;
— parameters added to Clause 5: quantity, copper and zinc content, phosphonates content, dry matter
content, chloride content.
— Annex ZA updated.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
Introduction
Regulation (EU) 2019/1009 [6] lays down the rules on the making available on the market of EU
fertilizing products and the specific safety, quality and labelling requirements for the defined product
function categories (PFCs). Liming materials have been classified as PFC 2.
In this document the normative references of the test methods to be used for liming materials (PFC 2) are
defined in order to measure the compliance with the related requirement in Regulation
(EU) 2019/1009 [6].
Supplementary denominations and specifications widely used in Europe are given in EN 14069 [5].

1 Scope
This document is applicable to liming materials, which contain oxides, hydroxides, carbonates or silicates
of the nutrients calcium (Ca) or magnesium (Mg) and the function of which is to correct soil acidity.
This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the
following components fertilizers, liming materials, soil improvers, growing media, inhibitors, plant
biostimulants and where the following category liming materials is the highest % in the blend by mass or
volume, or in the case of liquid form by dry mass. If liming materials is not the highest % in the blend, the
European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed
of components in equal quantity, the user decides which standard to apply. Variations in analytical
methods for fertilizing product blends can lead to differing results as some components or matrix
interactions can affect the outcome. Validation procedures have shown that developed standard methods
are robust and reliable across diverse product compositions, but possible interferences and unexpected
results when analysing fertilizing product blends are possible.
In case of chromium VI determination, in a fertilizing product blend containing organic matter, the
European Standard for liming materials and inorganic fertilizers is not applicable.
This document specifies references to the methods for the determination of the following physical and
chemical properties and specific contaminants in liming materials:
— determination of the cadmium content;
— determination of the chromium VI content;
— determination of the mercury content;
— determination of the nickel content;
— determination of the lead content;
— determination of the arsenic content;
— determination of the total chromium content;
— determination of neutralizing value;
— determination of the reactivity;
— determination of the grain size/granulometry;
— determination of the total CaO content;
— determination of the total MgO content;
— determination of the dry matter content;
— determination of the copper and zinc content;
— determination of the phosphonates content.
