From the mid 1980 s the rise of Quahty Standards, Total Quahty Management and Accreditation schemes created a booming demand for RMs and CRMs. Thus, the use and production of matrix RMs rapidly increased the new IAEA database lists 56 producers from 22 cormtries and about 1640 RMs. The 1998 Comar database, which covers a much wider scope, hsts more than 200 producers and around 10 000 RMs see Chapter 8 for more details.

The first reference material data base was established in 1984. Using what was then state of the arf software [dBASE 3 and Clipper ] the Code of Reference Materials (COMAR), was developed. By the release of the last edition at the beginning of 1999 it contained information on more than 10 000 RMs from over 200 producers in over 20 countries.

The next generation of COMAR will be an Internet-based Information center for CRMs which uses the well established structure see Figure 8,1.
