MAIN OBJECTIVES OF ISO 14224

To specify the data to be collected foranalysis:

System design and configuration;

Safety, Reliability and Availability of systems and plants;

Life cycle cost;

Planning, optimization and execution of maintenance.

To specify data in a standard format to:

Permit exchange of Reliability and Maintenance (RM) data

Ensure that RM data are sufficient quality for intended

analysis

HIGH QUALITY DATA

Completeness of data in relation to specification

Compliance with definitions of reliability parameters,

data types and formats

Accurate input, transfer, handling and storage of data

(manually or electronic).

EQUIPMENT BOUNDARY & HIERARCHY

A clear boundary description is imperative for collecting,

merging and analyzing Reliability & Maintenance data

from different industries, plant or sources (data

compatibility requirement) For each equipment class, a boundary shall be defined

indicating what Reliability & Maintenance (RM) data are

to be collected.

EQUIPMENT HIERARCHY

Preparation of a hierarchy for the equipment is recommended

The highest level is the equipment unit class

The number of levels for subdivision will depend on the

complexity of the equipment unit

The reliability data severity class shall be related to

equipment unit, while the failure cause shall be related to the

lowest level in the equipment hierarchy

A single instrument may need no further breakdown, whileseveral levels are required for a compressor

A subdivision into three levels for an equipment unit will

normally be sufficient.
