IEC 60319:1999 pdf download.Presentation and specification of reliability data for electronic components
1 Scope
This International Standard gives guidance for the necessary to understand the reliability characteristics of component users as to how they should specify their manufacturers. It makes no distinction between data on collection and presentation of data a component. It also gives guidance to reliability requirements to component failures or operation without failures or faults. Such factual information, derived from laboratory tests, should be available to the circuit and equipment designers to enable evaluation of the reliability of circuits and systems.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendment to or revisions of any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of IEC and ISO maintain registers of currently valid International Standards.

4 Requirements for presenting reliability data
4.1General
Where possible, information should be obtained by the use of standard reliability tests.
However, if some of the required data do not exist then steps should be taken to obtain them
by the use of dedicated tests.
If this is not possible, then generic estimates or data from equivalent devices may be used
assuming that this is stated in the data presentation.
The following or similar data should be supplied by the component manufacturer or requested
by the component user: component identification, component technology, electrical
specification, environmental specification, methods for selection of sample components, test
related issues, data on failures.
4.2 Identification of components tested
4.2.1 General
The information supplied to identify the components should be in accordance with the relevant
IEC publication for the component type under test whenever possible. If IEC publications are
not available, then other component specifications should be used and the source of the
specifications stated. As a minimum, the following information should be given. Only
information applicable to a particular component type should be supplied.
4.2.2 Component identification
a) A description of the component type with sufficient details to uniquely identify the
component type, for example N-channel V-MOS transistor. When available, specification
numbers should be given.
b) The component part number. If available, a universal part number, for example stock
number, should be given; otherwise a part number specific to the component manufacturer
may be given.
c) Name of the manufacturer and place of manufacture. The purpose of these references is to
allow access to more detailed information if required.
d) The date of manufacture or lot number or other production batch related identification. This
information will allow access to other components that were produced at the same time as
the sample should a problem arise.
e) The production status of the component, for example development sample, pre-production,
standard production, mature technology.
4.3 Information regarding compliance with other recognized standards should be given
whenever possible.
