EXAMPLE 1 A material certificate states the chemical composition of one or more physical pieces of material, for example, purchased raw material. The presence of the material certificate removes the need to test the composition of the material; it allows the specified material composition to be accepted as fact without further investigation.
EXAMPLE 2 A certified supplier can supply goods that do not require checking.
This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11.

Each reference to this schema in an open system shall use the identifier encoding specified in Annex B. This schema is illustrated in Annex D using the EXPRESS-G notation.
