ISO 14224 Maintenance Standard

ISO 14224 MAINTENANCE STANDARD Dr. Ir. EDI LEKSONO

MAIN OBJECTIVES OF ISO 14224  To specify the data to be collected for

analysis:  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

2

ISO 14224 MAINTENANCE STANDARD

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).

ISO 14224 MAINTENANCE STANDARD

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, while several levels are required for a compressor



A subdivision into three levels for an equipment unit will normally be sufficient.

INFORMATION STRUCTURE  Data categories

 Equipment data  Failure data  Maintenance data

 Data format  Facilitation of queries and analysis of data  Ease of data input

 Consistency check  Database structure

ISO 14224 MAINTENANCE STANDARD

EQUIPMENT DATA  Identification data : equipment location, classification,

installation, equipment unit data;  Design data: manufacturer’s data, design characteristics;  Application data : operation and environment

9

ISO 14224 MAINTENANCE STANDARD

FAILURE DATA  Identification data, failure record and equipment location;

 Failure data for characterizing a failure : failure date,

maintenance items failed, severity class, failure mode, failure cause, method of observation.
