Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,

Introduction
This document specifies the methods to be used for the determination of quantity of plant biostimulants
products sold or offered for sale. It is relevant to the quantity declarations given in European Regulation
2019/1009. Wherever possible, quantity determination checks shall be carried out at the premises of the
packer/importer/seller.
This document was prepared by the experts of CEN/TC 455 “Plant Biostimulants”. The European
Committee for Standardization (CEN) was requested by the European Commission (EC) to draft
European standards or European standardization deliverables to support the implementation of
Regulation (EU) 2019/1009 of the European Parliament and of the Council of 5 June 2019 laying down
rules on the making available on the market of EU fertilising products (“FPR” or “Fertilising Products
Regulation”). This standardization request, presented as M/564, also contributes to the Communication
on “Innovating for Sustainable Growth: A Bio economy for Europe”. Working Group 5 “Labelling and
denominations” was created to develop a work program as part of this standardization request.
Technical Committee CEN/TC 455 “Plant Biostimulants” was established to carry out the work program
that will prepare a series of standards. The interest in biostimulants has increased significantly in Europe
as a valuable tool to use in agriculture. Standardization was identified as having an important role in
order to promote the use of biostimulants. The work of CEN/TC 455 seeks to improve the reliability of
the supply chain, thereby improving the confidence of farmers, industry, and consumers in biostimulants,
and will promote and support commercialization of the European biostimulant industry.
1 Scope
This document specifies the methods to be used for the determination of quantity of solid and liquid
forms of plant biostimulants in packages, containers or in bulk.

3.11
container
closed receptacle directly in contact with a plant biostimulant whereby the plant biostimulant may be

4 Method of quantity determination
4.1 Quantity declaration
The quantity in terms of mass or volume of plant biostimulant shall be at least the nominal quantity stated
on the container or documentation associated with the product. The unit of measurement (weight or
volume) used for the quantity declaration should comply with national regulations where they exist.
4.2 Determination of quantity of product in solid and liquid form when sold by mass
4.2.1 Apparatus
A suitable weighing instrument.
“Suitable” means of a type sufficiently accurate to determine the actual quantity of the product (gross
weight) and mass of the packaging used so that a net quantity of the contents can be determined.
“Suitable type” means an instrument that complies with the requirements of EN 45501:2015.
“Sufficiently accurate” means that the scale intervals and sensitivity of the instrument are appropriate to
detect the quantity of the product and of the package/wrapping. This will depend on the nominal quantity
of plant biostimulant being weighed.
NOTE An indication of appropriate maximum scale interval is given in Annex A.
4.2.2 Equipment checks
Before using the weighing machine to establish the quantity of a plant biostimulant the machine should
be checked for accuracy with weights which comply with OIML R111 and having an accuracy tolerance
of one third the maximum error for the weighing machine under test. The tests are laid down by
EN 45501:2015.
A record should be kept of the results of the tests.
NOTE Because half a graduation can be read on an analogue indicator weighing instrument weight display,
digital instruments will need to indicate 50 % of those for an analogue graduation.
4.2.3 Method
4.2.3.1 Packages under 25 kg
Place the package on the weighing plate of the weighing instrument and record the mass shown (x).
Weigh 10 randomly selected empty containers (non-destructive testing) or if empty containers are not
available empty 10 randomly selected containers already weighed after ensuring no product remains in
or on the containers (destructive testing).
NOTE Because of the small mass of the containers, a more sensitive weighing instrument can be used for this
operation see Annex A.
Record the masses and obtain an average mass of the containers (y). Record the calculation and result.
Subtract the mean mass of the container from the gross quantity of each packed fertilizing product and
calculate and record each net quantity (z) using Formula (1).

z is the net quantity by mass of the conte
