Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture

and forestry, Subcommittee SC 6, Equipment for crop protection.

3.1
sample concentration

concentration of a sample calculated by the ratio of the mass of the dried sample to the mass of the

liquid suspension (dry material + water)
4 Test setup
4.1 Measuring equipment
4.1.1 General
Measuring equipment shall comply with ISO 5682-1:2017, Clause 4.
4.1.2 Scale for evaporator samples

The scales for weighing evaporator dish/jar samples before and after evaporation shall have a minimum

range of 0 g to 100 g with a maximum error of 0,001 g.

ISO/FDIS 5682-4:2021(E)
4.1.3 Scale for test material

The scale used for measuring test material added to the spray tank shall have a maximum error of

0,1 % of the measured value.
4.2 Sampling methods and measuring concentration
4.2.1 General

This subclause defines methods for sampling and measuring concentration of the liquid suspension

during preparation and testing.
4.2.2 Sample size

A sample size of 20 ml to 100 ml shall be used. The sample size chosen shall meet the error in 4.2.5.

Each sample shall be analysed individually (for example, do not mix samples prior to measuring

concentration). Several samples may be taken, and the concentration calculated as the average of the

individual samples’ concentrations.
4.2.3 Tank sampling

Spray tank samples shall be taken at 90 %, 50 %, and 10 % levels of the tank nomin
