Surfaces for sports areas - Code of practice for the sampling of performance infills used within synthetic turf surfaces

This document describes the minimum procedures for the sampling of performance infills used within synthetic turf surfaces to verify compliance with toxicology, environmental and performance regulations and standards.  
Four sampling procedures are specified:
Method 1 is intended based on taking samples during production of the infill material.  
Method 2 describes how to take samples from big bags.
Method 3 describes how to take samples from small bags.
Method 4 describes a procedure for taking samples from a synthetic turf (e.g. sports, recreational or landscaping surface).  
The procedures described are suitable for all forms of infill.

4 General
The method of sampling employed shall be designed and controlled to ensure that contamination of the
increment, lot, sample, test portion or test sample cannot occur.
When laboratory samples are being taken for chemical analysis increments and samples shall be stored
in containers that are known to not influence the results of the analysis.
NOTE Metal or glass containers are considered to satisfy this requirement.
All equipment shall be thoroughly cleaned before use.
5 Method 1 — sampling during production
5.1 Sampling plan
The main principle of sampling is to obtain a representative sample(s) from a lot of material from which
a characteristic is to be determined. If the lot is to be represented by a sample, then every particle in the
lot shall have an equal probability of being included in the sample.
When these principles cannot be applied in practice, the sampler shall define a judgemental sampling
procedure that is designed to ensure the sampling matches as far as possible the outcomes of probability
sampling and note any limitations of the procedure used in the sampling plan and sampling report.
Obtaining samples that are truly representative of the material produced is easier when the material is
falling or moving (for example on a conveyor belt). Therefore, sampling from falling or moving material
shall be undertaken wherever possible.
A sampling plan shall be prepared before samples are taken. This shall include a specific definition of the
lot size and the size and number of increments to be taken.
5.2 Lot size
The minimum lot size shall be 10 t and the maximum lot size shall not exceed 120 t of product.
NOTE 1 A lot size of 120 t is based on the typical quantity of infill used on a 60 mm full size synthetic turf football
field.
6

---------------------- Page: 8 ----------------------
SIST EN 17409:2020
EN 17409:2020 (E)
When determined by the producer the lot size may be defined as:
a) a fixed quantity produced between machine settings;
b) a fixed quantity in a production day/shift;
c) a fixed quantity;
d) a quantity produced in a fixed time frame.
NOTE 2 Option d) is most appropriate for continuous production with no beginning and no end.
5.3 Sampling point and apparatus
Based on health and safety assessments and producer equipment, a fixed sampling point for the collection
of sample increments shall be chosen for each material fraction to be monitored. Sampling shall be carried
out using a sample box or other suitable equipment.
The sampling box shall be passed through the stream of falling material so that it uniformly cuts the full
flow of falling material. The box shall be large enough so that it does not become overloaded. Automatic
systems fulfilling these criteria may also be used.
NOTE A procedure for preparing samples for chemical analysis is given in Annex A.
5.4 Size of sample increment
3
The sampling box shall have a capacity of not less than 0,5 l (0,000 5 m ).
The sampling operator shall record the approximate capacity of the sampling device in cubic decimetres.
5.5 Number of increments
One increment shall be taken per 10 t of produced infill, with a minimum of four increments per lot.
Where daily or weekly production quantities are small, the taking of increments should be increased to
ensure the lot comprises at least four increments.
6 Method 2 — sampling from big bags
6.1 Principle
The laboratory sample is created by mixing several increments removed with a sampling tool from at
least three levels, with at least one located on each level, as specified in 6.3.
6.2 Apparatus
6.2.1 Sampling tool
This tool shall be designed to take samples of dry or slightly cohesive wet materials,. It shall be shaped in
such a way to allow the operator to reach different heights by simply screwing the tool into the big bag.
Its opening shall be wider than three times the size of the largest particle expected to be present in the
big bag.
6.2.2 Measuring flask

Container of known volume; greater than 1 l (0,001 m ).

6.3 Procedure
6.3.1 Sampling
Using the sampling rod take, at least, three increments at different heights in accordance with 6.3.2 within
the big bag as follows:
1. Close the container on the sampling rod (see Figure 1):

Figure 1 — Sampling rod
2. Insert the sampling rod into the big bag and twist in a clockwise direction from the top of the big
bag (see Figure 2):

Figure 2 — Rotating sampling rod in big bag
3. When the sampling depth has been reached, open the sampling container by turning the sampling
rod in the opposite direction.
4. Make three full rotations in the same direction to fill the container.
5. Twist the sampling rod in counter-clockwise direction in order to close the container.
6. Pull out the sampling rod and empty into the sampling container.
7. Repeat procedure to collect increments in the middle of the big bag, and then at the bottom of the
big bag.
