Preferred Label : umpire sample;
IUPAC definition : A sample taken, prepared and stored in an agreed upon manner for the purpose of settling
a dispute. The agreement usually extends beyond the sample to the basis for reaching
a decision (e.g. quantity of material from which taken, use of a third party and criteria
serving as the basis for acceptance, rejection or economic adjustment). The term 'reference
sample' has been used in this context but this term more properly should be used in
conjunction with a 'reference material' or 'reference standard' which has a true or
assigned value for a constituent or property. One of the characteristics of a reference
material or reference standard is that it must have a negligible sampling error between
test portions.;
