PDEA
Peocedure whereby a part of a substance, marerial or product is taken to provide for testing or calibration a representative sample of the whole.
Sampling
This refers to the pile of a material not in the form of separate permanently identifiable units
Bulk materials
Compirsed of identififiable units which may be assigned numbers
Packaged materials
These are bulk materials that are partialy packaged into smalled units such as bags or drums
Segment
Quantity of the material transferred on one occasion and covered by a single set of shipping documents
Consignment
Refers to the quantity of material which is assumed to represent a single population for sampling purposes
Lot
Refers to the quantity of material which is known or assumed to have been produced under uniform conditions
Batch
Are portions of the material obtained from the lot/batch by using sampling device
Increment
A result of combined increments
Primary or gross samples
Results from a number of primary samples combined and mixed
Composite or aggregate
Obtained from primary or composite sample by a series of division and reduction process
Lab sample
Refers to the quantity of material that is actually submitted for analysis also called analytical portion
Test portion
Samples with characteristics the same as that of parent material
Representative smple
Obtained by choosing certain portion of the material possesing the desired characteristics to be analyze
Selective sample
Two or more portions of the materials collected at the same time
Composite sample
This is performed when statistical evaluation is jeeded tto be employed on the set of data
Probability sampling
A probability sampling where any sample has an equal chance of selection
Simple Random sampling
A lot is subdivuded where a simple random sample is selected from each stratum
Stratified random sampling
The first sample is selected randomnly and then subsequent sampmes are taken according to a previously arranged interval
Systematic random sampling
This type of sampling is performed when a representative sampme is not appropriate hence results in selective samples
Non probability sampling
Knowledge about the material is required to select the desired specific samples
Judgement sampling
The materials are subdivided into groups where a sample is selected from each group
Quota sampling
Non prob sampling performed when selecting a sample that depends on its availability and accessibility
Convenience sampling
Involves seection of a sample from material which dies not cinsusy of discrete identifiable or constant units
Bulk sampling
It invoved the use ot predetermined sampling pman to determine if the batch of materials meets the defined criteria for acceptance
Acceptance sampling
