Standards are developed on a demand basis and the need for a new standard can be initiated by an individual, a manufacturer, or a government institution. A new standard is developed when it is realized that there is a need for the standard. A new type of product might need standardizing. An industrial process might need to be regulated to protect workers or consumers.
The role of UNBS is to manage the processes of standard development using internationally recognized best practices once the need for a new standard has been realized.
