Guidance on sampling for testing.39SIST EN 13383-2:2002
The correct use of the specified apparatus and methods helps to avoid biased sampling inclusivethe possibility of human bias introduced by visual selection.
Sampling variation caused by the heterogeneityof the batch shall be reduced to an acceptable level by taking an adequate number of sampling increments.NOTESee annex G for guidance on numbers and sizes of samples and test portions for testing armourstone asspecified in EN 13383-1:2002.Sampling increments are selected at random from all parts of the batch that the samples are to represent.Armourstone from which no sampling increment can be taken (because it is not accessible, or for some otherpractical reason) shall not be considered to be part of the batch that is represented by the samples. Forexample, if sampling increments are taken from armourstone discharged from a silo, the samples representthe armourstone that has been discharged, not the armourstone remaining in the silo.The sampler shall be informed of the aim of the sampling.4.3 Sampling planA sampling plan shall be prepared, prior to sampling, taking into account the grading type, the nature andsize of the batch, the local circumstances and the purposes of sampling.
It shall include:a) the type of the armourstone;b) the aim of the sampling including a list of the properties to be tested;c) the identification of the sampling points;d) the mass or number of stones of sampling increments;e) the number of sampling increments;f) the sampling apparatus to be used;g) the methods of sampling and sample reduction with reference to the clauses of this EuropeanStandard;h) the relevant marking, packaging and dispatch of the samples.SIST EN 13383-2:2002

Those involved in the planning and execution of sampling should work closely with the operationalmanagement to ensure safe working practices.NOTE 2Mechanically selected gradings should preferably be sampled from a stationary conveyor belt or from thestream of material.
Sampling increments should be taken at regular intervals througout the period the batch is in motion.Gradings of which the pieces of armourstone are individually handled can be sampled at the most convenient location.NOTE 3Sampling from static batches should be avoided wherever possible since it is difficult to satisfy the principleof taking sampling increments at random from all parts of the batch, and hence segregation is likely to cause thesampling to produce biased results.During sampling, grabs or
