Overview
• RAMS parameter
MIL-Handbook 127, ISO 14224 (OREDA), ISO 6527,
etc.
Taxonomy of parameters
• Scheme of information element
• Components of Information System

RAMS parameter
• Operational information
Operating pressures & temperatures, materials of construction, medium characteristics, age
• Equipment data
describing the "life" of some equipment notably related to failures and maintenance.
• Event data
describing all events concerning the system functioning, maintenance, etc. These data can be divided into classes:
o failure data: information about all accidents/incidents (time of happening of event, site, conditions, consequences, persons involved, etc)
o maintenance data – information about corrective and preventive maintenance (time, duration, conditions, cost, etc);

Aim:
• Collection of reliability and maintenance (RM) data in a
standard format for equipment in all facilities and
operations within the petroleum, natural gas and
petrochemical industries during the operational life cycle of
equipment
• Defines equipment taxonomy and standard processes for
collection, merging and analysis of reliability data
Key Aspects
• Equipment data e.g. class boundary definitions
• Failure and activity codes
• Time definitions
• Consequence severity assessment
• Quality of data e.g. completeness of data
ISO 14224:2016

Taxonomy
• systematic classification of items into generic groups based on factors possibly
common to several of the items
ISO 6527:1982 Nuclear power plants - Reliability data exchange - General guidelines

This standard was last reviewed and confirmed in 2015. Therefore this version remains current.
This standard identifies the typical parameters of a component that permit it to be characterized
unequivocally and to allow the corresponding reliability data to be associated with those of other
components having equivalent typical parameters. Parameters refer to technical characteristics
including the physical principle of operation and quality level and to actual operating conditions
and maintenance and test intervals.
• Component characteristics are separated into
• Technical characteristics
• Quality characteristics
• Operation characteristics
• Normal operating conditions
• Maintenance and test intervals
• Environmental conditions
• Failure data may be represented both
• in a historical and
• in a statistical form.
• Mode-of-failure classification
• The failures shall be linked to their
mode of failure

In this proposed scheme the COMPONENT is the smallest unit. Each
component has a defined component boundary.
