3 Terms and definitions
For the purposes of this standard, the following term and definition applies.
3.1
batch
a quantity of admixture which can be considered to have a uniform composition
Note A tank load can be considered as the equivalent of a batch.
4 Sampling
4.1 General
Sampling of admixtures shall be carried out in such a way that the resulting sample is representative of the batch
to be inspected.
If required, sampling shall be carried out in the presence of representatives from all parties involved.
4.2 Sampling from the manufacturer's stock
4.2.1 General
Each sample shall represent not more than one batch. For continuous production of an admixture one sample taken
from up to 25 t may be regarded as representative.
4.2.2 Powder admixture (in packages)
The sample shall be composed of sub-samples from 6 packages (bags) or if the total number of packages (bags)
is less than 6, from all packages (bags). The sub-samples are to be taken from packages (bags) distributed at
random throughout the consignment.
One of the following procedures shall be applied:
– Where the packages contain up to 500 g take all the contents of each package.
– Where the packages contain more than 500 g, use one of the following methods:
a) insert a sampling tube, which takes a core not less than 25 mm in diameter, into the packages so that it takes
a core of the material from substantially the entire length of the package.
b) empty one of the packages to be sampled on to a clean dry surface and mix the material. Take at least three
portions of not less than 125 g each from different parts of the heap.
The method given in a) is the preferred method, but if a sampling tube is not available, the method given in b) shall
be used.
Repeat the procedure with each of the other packages to be sampled and thoroughly mix the sub-samples obtained to
form one bulk sample. If the bulk sample exceeds 3 kg it shall be reduced to 3 kg, either by coning and quartering or
by use of a sample splitter.
Divide the sample into three equal parts and place each part in a clean, air tight, labelled container. At least one
container holding 1 kg shall be kept for future reference. Store container(s) in a place that is protected from moisture,
heat and light for one year or until the use-by date whichever is the shorter period.
4.2.3 Liquid admixture
4.2.3.1 General
In order to achieve representative samples of liquid admixtures one of the following procedures shall be applied.

SIST EN 934-6 : 2002
4 Vzorčenje
4.1 Splošno
Vzorčiti je treba tako, da se dobi reprezentativen vzorec šarže, ki jo je treba pregledati.
