This part of ISO 13584 specifies the requirements for an ISO-registered reference dictionary for measuring instruments with their descriptive properties and domains of values. The measuring instruments to be included in the dictionary comprise environment measuring instruments and laboratory measuring instruments.
This part of ISO 13584 also specifies the procedures of an organization that develops, maintains and updates the reference dictionary for measuring instruments over a specified period of time. Such an organization is nominated by ISO and is referenced in this part of ISO 13584 as the registration authority of the reference dictionary for measuring instruments.
The reference dictionary for measuring instruments contains the following:
  • — definitions and identifications of classes of measuring instruments, with associated classification scheme;
  • — definitions and identifications of data element types that represent properties of measuring instruments;
  • — definitions and identifications of domains of values that prove useful for describing the above data element types.
Each class, property or domain of values of this application domain constitutes an entry of the reference dictionary for measuring instruments defined by the registration authority. It is associated with a computer sensible and human readable definition, and with a computer sensible identification. Each dictionary entry has an identifier that allows it to be referenced unambiguously from any application.
Definitions and identifications of dictionary entries are defined by means of standard data that consist of instances of the EXPRESS entitydata types defined in the common dictionary schema, and in its extensions defined in ISO 13584‑24 and ISO 13584‑25.
The following are within the scope of this part of ISO 13584:
  • — requirements on the standard data that is used to represent the various classes of measuring instruments, together with their descriptive properties and domains of values;

    NOTE 1 Descriptive properties can include properties concerning regulations on manufacturing, operation, maintenance, disposal and recycling of the product.

  • — the process to be followed by the registration authority to propose and validate an initial version of the reference dictionary for measuring instruments;
  • — the process to be followed by the registration authority to collect, validate and register new entries or update entries for the reference dictionary for measuring instruments;
  • — the process to be followed by the registration authority to distribute the reference dictionary for measuring instruments.

    NOTE 2 The measuring instruments considered in this part of ISO 13584 include those measuring instruments that are classified in the classes ICS 13 (Environment. Health protection. Safety), ICS 71.040 (Analytical chemistry) and ICS 17.220 (Electricity. Magnetism. Electrical and magnetic measurements).

    NOTE 3 The file format with which the standard data registered by the registration authority established by this part of ISO 13584 can be exchanged is specified in ISO 10303‑21.

    The following is outside the scope of this part of ISO 13584:
  • — the standard data themselves that constitute the content of the reference dictionary for measuring instruments.

    NOTE 4 The standard data themselves that constitute the content of the reference dictionary are registered by an ISO registration authority, but are not ISO-standardized.

    NOTE 5 The standard data contain the definitions and properties of measuring instruments specified above, but they are not necessarily of measuring equipment. The difference in definitions between measuring equipment and measuring instruments is explained in IEC 60050‑351.
