Materials standards and codes are the common language between specifiers, buyers and producers.
Quality requirements are at the root of materials standards and codes.
Specifying and ordering materials are simplified by using materials standards and codes so that required performance characteristics may be achieved in service.
The eight major categories that the code covers are scope; design conditions; pressure design; flexibility and stress intensification; materials; standards; fabrication and assembly; and inspection, examination, and testing.
After material needs have been met, research has repeatedly shown that further rises in material standards contribute less and less to wellbeing.
The United Nations Development Program UNDPP)'s HDI has been used since 1990 to compare countries in terms of "human development", defined as the enlargement of choices made possible by education and literacy, a decent material standard of living, and a long and healthy life.

Product analysis, ester groups and physio-chemical properties were obtained by gas chromatography, Fourier transform infrared spectroscopy and American Society for testing and material standard methods, respectively.
Once fully completed, this collaborative and interdisciplinary framework can be the basis of Virtual Materials Testing standards and aids in the development of new material formulations.
Health is measured using life expectancy, knowledge is measured via educational participation and adult literacy rates, and the material standard of living is captured by GDP per capita, reported in Purchasing Power Parity (PPP) dollars.
