Something which is specifically created to define a standard can be referred to as a prototype one notable example being the International Prototype Kilogram. Although the meaning can change with context and can also refer to an early or test version which is later further refined and developed.

In some contexts the adjective definitive can also be used for emphasis (an this term is indeed used of stamps). For example you might say that something is a definitive version of a document.

Another possibility, especially when an object is being duplicated mechanically or electronically is a master.

All of the above are appropriate when you are talking about something used as a reference in a design, manufacturing or reproduction process.

Also benchmark may be used especially when you are trying to compare complex or ambiguous systems to get a measure of relative performance although this often implies a testing prcess or procedure rather than a physical reference sample.
