Introduction
This document deals with the determination of the content of inorganic substances in construction
products.
Following an extended evaluation of available methods for content analysis in construction products
(CEN/TR 16045) it was concluded that eluate analysis methods are very similar to analytical methods
used to determine content after digestion of a solid matrix.
This document has a similar structure as EN 17195.
This document is part of a modular horizontal approach which was adopted in CEN/TC 351. “Horizontal”
means that the methods can be used for a wide range of materials and products with certain properties.
“Modular” means that a test standard developed in this approach concerns a specific step in assessing a
property and not the whole chain of measurement (from sampling to analyses). Beneficial features of this
approach are that modules can be replaced by better ones without jeopardizing the standard chain and
duplication of work of in different Technical Committees for Products can be avoided as far as possible.
Similar standards have been developed for content determination in different types of matrices, see
Annex A (informative).
The modules that relate to the standards developed in CEN/TC 351 are specified in CEN/TR 16220, which
distinguishes between the modules. This document belongs to the analytical step.
The use of modular horizontal standards implies the drawing of test schemes as well. Before executing a
test on a certain construction product to determine certain characteristics, it is necessary to draw up a
protocol in which the adequate modules are selected and together form the basis for the entire
test procedure.

For analytical quality control purposes ISO/TS 13530 and EN ISO/IEC 17025 should be considered.
6.2 General validation information
A selection of the test methods listed in Table 1 has been validated in robustness validation ([ALS, 2017],

It is pointed out that the standardized test methods listed in Table 1 have primarily been developed for
the analysis of water samples. Most of them were validated by CEN/TC 223, CEN/TC 292 and
CEN/TC 308 in interlaboratory trials for a limited number of digests from various matrices. The
validation data on these other matrices obtained in
