A standard specification is a specification of a type of product, or in general of a kind of thing. Such specifications are standardised so that many individual things can be created that comply with those specifications. In that sense the specifications can also be interpreted as requirements for the creation of individual things. The standard specifications may be company specific such as Best Practice Design Specifications or Buyers Standard Specifications or they may be published by industry consortia or national standardisation bodies, such as ANSI, BSI, DIN or JIS or by international standardisation bodies, such as ISO and IEC.

A standard specification model is not a product model about an individual object nor a model of a 'typical individual thing' or a prototype, but a standard specification model defines a kind of thing, whereas that kind is used in situations in which the specification is declared to be applicable. For example, many standards institutes provide standard specifications that specify that particular kinds of things shall satisfy the specification in those standards in order to ensure a certain product quality. Sometimes those institutes provide the possibility that products can be certified if they satisfy the specifications. Standard specification models are defined in Gellish in the same way as Requirements Models. They have a similar structure as knowledge models, but use other relation types. Standard specification models are collections of facts, each of which express either that something shall be the case or that something is by definition the case. This means that Gellish expressions will be used which phrases start with <shall be…> or <shall have…> or phrases that start with <is by definition…> or <has by definition…>.
