Kodning av information

This standard defines the identification, data, information services, application guidance aspects, and applicable requirements of AIDC technology for different items and their hierarchy in Industrial
Construction during their whole life-cycle. It:
— provides unique identification for items in Industrial construction.
— specifies the semantics and data syntax to be used.
— specifies the data carriers to be used on items of various categories, substitutes, and sizes.
— makes recommendations about the metadata of the items.
— specifies the application test method and parameters based on the large scale test and scientific sampling rules.
— define the information services protocol to be used as interface between business applications and the AIDC system.
— makes guidance for designers, workers, engineers, managers, end users and maintainers about the AIDC application in their daily work.

This document
— specifies two methodologies for the measurement of specific attributes of two-dimensional bar code symbols, one of these being applicable to multi-row bar code symbologies and the other to two-dimensional matrix symbologies;
— defines methods for evaluating and grading these measurements and deriving an overall assessment of symbol quality;
— gives information on possible causes of deviation from optimum grades to assist users in taking appropriate corrective action.
This document applies to those two-dimensional symbologies for which a reference decode algorithm has been defined, but its methodologies can be applied partially or wholly to other similar symbologies.
Note While this document may be applied to direct part marks, it is possible that better correlation between measurement results and scanning performance will be obtained with ISO/IEC 29158 in combination with this
document.
