3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
3.1
batch
quantity of admixture which can be considered to have a uniform composition
Note 1 to entry: A tank load can be considered as the equivalent of a batch.
3.2
responsible person
person appointed by the manufacturer whose duties include implementation of all or a defined part of
the production control manual
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.
The following procedures shall be used:
— for type testing and in case of dispute, 4.2;
— at time of delivery, 4.3;
— for factory production control, 4.4.
If required, sampling shall be carried out in the presence of all the parties concerned.
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:
a) where the packages contain up to 500 g, take all the contents of each package;
b) where the packages contain more than 500 g, use one of the following methods:
1) 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;
2) 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 1) is the preferred method, but if a sampling tube is not available, the method
given in 2) 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.
4.2.3.2 Sampling of a liquid admixture from containers
The sample shall be composed of sub-samples taken from 6 containers or if the total number of
containers is less than 6 from all containers. The sub-samples are to be taken from containers
distributed at random throughout the consignment.
