Dependability management -- Part 3-2: Application guide - Collection of dependability data from the field
This part of IEC 60300 provides guidelines for the collection of data relating to reliability, maintainability, availability and maintenance support performance of items operating in the field. It deals in general terms with the practical aspects of data collection and presentation and briefly explores the related topics of data analysis and presentation of results. Emphasis is made on the need to incorporate the return of experience from the field in the dependability process as a main activity. This standard can be applied during monitoring of a population sample or, more widely, of whole populations. It is applicable, without restriction to diverse items, from components to systems and networks, including hardware, software and man/machine interactions. The items considered may have been designed, manufactured, installed, operated and maintained by one or more organizations. This standard applies to all possible relationships between suppliers and users. It applies to situations where some items may be repaired on site while others may only be replaced on site and repaired at centralized facilities. No recommendations are made, however, of how to organize maintenance support.

Collection of dependability data from the field
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60300-3-2 has been prepared by IEC technical committee 56:
Dependability.
This second edition cancels and replaces the first edition, published in 1993, and constitutes
a technical revision.
The standard has been totally rewritten to provide more generic, and less component specific,
data collection guidance. The new standard addresses the issues of the underlying data
collection philosophy, such as sampling, censoring, and window data. The standard also gives
guidance on accuracy and precision, automated data collection techniques and data
stewardship. In order to support the toolbox concept, the standard identifies the data
requirements of a number of other IEC standards.

INTRODUCTION
The collection and analysis of failure and usage data from the field plays an important role in
dependability analysis. It enables:
a) maintenance planning;
b) justification of modifications;
c) calculation of future resource and spares requirements;
d) confirmation of contractual satisfaction;
e) assessment of likelihood of achieving a successful mission;
f) feedback to design and manufacturing;
g) estimation of cost of warranty period;
h) improve dependability requirements;
i) collection of basic data for possible liability cases;
j) collection of usage data to determine field customer requirements which provide the basis
for supplier dependability test specifications and demonstration programs.
Data collection for dependability-related purposes is often a long-term activity. Data covering
a lot of item operation and/or many items may be required before appropriate analysis can be
completed. Data collection should be undertaken as a planned activity, and executed with
appropriate goals in mind.
In the shorter term, data collection objectives for dependability-related purposes include:
1) identification of new product design shortfalls;
2) adjustment of logistic support;
3) identification of customer problems for correction;
4) root cause failure analysis to eliminate predominant failure modes in the next design.
Analysis of dependability data requires clear understanding of the item, its operation, its
environment and its physical properties. Analysis also needs good understanding of the
general subject of dependability and its manifestation in the specific application.
Before starting a data collection process, it is important to realize that data collection cannot
usually be performed without co-operation of all the parties involved. This may include item
manufacturers, suppliers, repair authorities, users and customers.

DEPENDABILITY MANAGEMENT –
Part 3-2: Application guide –
Collection of dependability data from the field
1 Scope
This part of IEC 60300 provides guidelines for the collection of data relating to reliability,
maintainability, availability and maintenance support performance of items operating in the
field. It deals in general terms with the practical aspects of data collection and presentation
and briefly explores the related topics of data analysis and presentation of results. Emphasis
is made on the need to incorporate the return of experience from the field in the dependability
process as a main activity.
This standard can be applied during monitoring of a population sample or, more widely, of
whole populations. It is applicable, without restriction to diverse items, from components to
systems and networks, including hardware, software and man/machine interactions. The items
considered may have been designed, manufactured, installed, operated and maintained by
one or more organizations. This standard applies to all possible relationships between
suppliers and users. It applies to situations where some items may be repaired on site while
others may only be replaced on site and repaired at centralized facilities.
No recommendations are made, however, of how to organize maintenance support.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
IEC 60050-191, International Electrotechnical Vocabulary (IEV) – Part 191: Dependability and
quality of service
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-191 and the
following apply.
3.1
environment
continuous or intermittent stress that may cause an event to occur (e.g. failure, a re-
replacement, etc.) for an item
3.2
events
things that happen to items
NOTE Events include such things as removals, insertions, and upgrades. Additionally, how many occurrences,
actuations, operating states, conditions, etc. are events that relate to product usage that can be evaluated from a
damage perspective, where damage equivalence can be obtained with a higher frequency of the damaging event
coupled with contributing damage factors from the application such as load, pressure, vibration, etc. Qualification
of a product or system relates to understanding the distribution of damaging events per the significant sources of
stress.

3.3
life
time between conception of the item and the time at which it is removed from operation.
4 Legal considerations
If a conflict should arise between this standard and the relevant contract or specification(s)
the latter should apply.
Since this standard requires several issues to be agreed on between the customer, the
manufacturer and a third party (if any), all contracts should refer to this standard and any
other standards which deal with dependability analysis or data collection procedures to be
employed.
In addition, the following applies.
Where selection of specific analysis or data collection techniques is concerned, the manner in
which analysis or data collection are to be performed, or any other tailoring of the standard for
purposes of the project is intended, the party given the discretion, and the areas in which
discretion is to be exercised should specifically be mentioned in the contract or analysis or
data collection specification.
Where specific analysis or data collection procedures is concerned, the manner of
performance of analysis or data collection, or other tailoring has to be agreed to, the agree-
ments should be stated in an annex in the contract or analysis or data collection specification.
Finally, where any matter requiring agreement has not been resolved, such areas should be
specifically identified in the contract or analysis or data collection plan, and suitable
provisions including deadlines for agreement and dispute resolution procedures should be
stated.
In all instances, the applicable contract or sub-contract should identify the party responsible
for performing the analysis or data collection, the party liable for consequence of failure to
comply with the specifications, the scope of or limitations of such liability, and the nature of or
limitations on remedies available to the damaged party, witnessing of or participation in the
analysis or data collection program by the customer.
5 Objectives of data collection
All customers' needs and expectations focusing on dependability can be categorized as
follows:
a) life time issues;
b) availability;
c) service issues;
d) cost of ownership issues;
e) operational reliability;
f) safety.
In addition, the consumers' point of view concentrates on
g) durability;
h) value for money;
i) service.
---------------------- Page: 14 ----------------------
SIST EN 60300-3-2:2007
60300-3-2 IEC:2004 – 17 –
In addition, professional customers may be interested in
j) validation of fulfilment of requirements of purchased items;
k) logistics optimization;
l) spare stock optimization;
m) maintenance optimization;
n) maintainability studies;
o) availability studies.
Society as a whole is interested in safety, low risk and security. Those aspects can be
influenced by dependability properties of items. Also economics is influenced by dependability
properties, therefore public interest exists.
From the manufacturer’s point of view the following aspects are important:
− comparison with similar products on the market;
− base for improvements for the next generation of the product.
Dependability can have different drivers within different sorts of companies. In general private
companies use dependability as a means of increasing or maintaining profits while
governmental or charity based companies use it as a means of maintaining a service. This
can mean that the different sorts of companies will collect dependability data for different
reasons.
The aim of data collection is to improve the relevant products and processes in any
organization. Collected data with appropriate analysis close the learning loop back to
marketing, design, manufacturing and service. Sub-targets can be risk minimization, cost
optimization or the check for conformity with given requirements. Data should be collected for
a purpose: to enable analysis, focused on increasing understanding of item operation and
failure, and application of this knowledge to a goal or objective. Without a definition of the
objective for the future data analysis and the application of its findings, collection of data is
likely to be aimless and will omit important data, allow corruption of data, or may waste time
and resources by including data that offer little benefit.
While planning data collection, several questions have to be considered such as the following:
1) What observed availability is achieved with the applied maintenance regime?
2) What values have been achieved with a former, similar product?
3) Does the product conform to the requirements?
4) What affect has environment and usage on dependability?
5) How stable is the dependability of manufactured items with time?
Further, it may be required to do the following:
6) Check compliance – to decide whether the product conforms to dependability
requirements.
7) Check prediction – to compare calculated and observed values.
8) Estimate for new item – to use achieved values as a basis for estimation of similar item.

9) Check influence of changes in processes – to compare dependability measures before
and after changes in manufacturing process.
10) Check influence of changes in product versions – to compare dependability measures of
different product versions.
11) Check stability of dependability measures of manufactured items with time – to compare
dependability measures of production lots.
12) Improve logistics – to re-plan the spare stock by use of real needs.
13) Check maintenance strategy – check the difference between inherent and real availability
and different strategies.
14) Optimize scheduled maintenance – to use the failure rate distribution of an item to find the
best maintenance/replacement.
15) Monitor for liability risk and possible product recall.
16) Investigate both fault occurrences and causes of no fault found causes – imperfect repair,
serial and systematic failures, test of software, patterns of failures and trends.
17) Obtain information about operational and environmental influences on the product and
output parameters for simulation requirements, customer based dependability
requirements, to guide test and simulation reliability specifications.
18) Identify troublesome components and their failure mechanisms.
19) Evaluate existing dependability models and derive new dependability models.
20) Evaluate dependability indicators.
21) Undertake logistic and resource planning.
22) Justify modifications.
23) Ensure contractual satisfaction.
24) Evaluate the need for remote condition monitoring to track item health.
25) Develop a corporate memory database, incorporating wider data collection, building on
individual data collection activities, with wider application of results.
26) Collect data to allow physics of failure analysis to be carried out. It is worth noting that a
full physics of failure analysis will have a large data requirement for basic physical
parameters of an item and the materials
