4 General
The whole package shall be handled in batches and all the packages of a same batch must be identical and include, in similar proportion, a single type of cork from those mentioned in the title of this document. Additionally, in the case of boiled reproduction cork that is grouped by thickness and/or quality, all packages of the same batch shall be identical in quantity as concerns to these parameters.
No more than 24 h shall elapse between the time of determination of the initial total mass of the batch and the time at which the laboratory samples are taken.
5 Sampling method
Count the total number of packages in the batch.
Determine the total initial mass of the batch (mass of packages included) by direct weighing.
From the whole batch, take randomly some packages containing the cork pieces, 5 packages minimum corresponding to a mass of at least 60 kg.
Open each package and determine the corresponding mass of each one. Extrapolate the value obtained for the total number of packages, thus obtaining the total mass of the packages.
From the different opened packages, collect randomly an equal number of cork pieces or parts of cork pieces), in order to obtain a total mass of approximately 30 kg of cork. If only part of a cork piece is to be collected, make sure that the part taken from the cork piece is representative of the whole piece of cork in terms of moisture content.BS ISO 2385 pdf download.
