21.020 - Characteristics and design of machines, apparatus, equipment

IEC 61163-2 provides guidance on RSS techniques and procedures for electrical,electronic, and mechanical components. This document is procedural in nature and is not, andcannot be, exhaustive with respect to component technologies due to the rapid rate ofdevelopments in the component industry.This document is:a) intended for component manufacturers as a guideline;b) intended for component users as a guideline to negotiate with component manufacturers onRSS requirements;c) intended to allow the p...view more

IEC TR 62998-2:2020 establishes guidance for the application of IEC TS 62998-1:2019.
It provides examples of:
– application for which SRS/SRSS are relevant,
– use of SRS/SRSS information from an application point of view,
– fusion of SRS into SRSS for given applications, and
– appropriate information for use for given applications.

EN-IEC 61123 is intended to define a procedure to verify if a reliability of an item/system complies with the stated requirements. The requirement is assumed to be specified as the percentage of success (success ratio) or the percentage of failures (failure ratio). This document can be used where a number of items are tested (number of trials performed) and classified as passed or failed. It can also be used where one or a number of items are tested repeatedly. The procedures are based on the as...view more

This document specifies the requirements for a digital mock-up virtual assembly test (VAT) for mechanical products, which is suitable for guiding virtual assembly testing before physical production. The application of this document is intended to result in an effective VAT and efficient on-site assembly. This test is applicable to 3D nominal models with theoretically exact dimensions.

This document gives guidance on the use of failure rate data for reliability prediction of
electric components used in equipment.
The method presented in this document uses the concept of reference conditions which are
the typical values of stresses that are observed by components in the majority of applications.
Reference conditions are useful since they provide a known standard basis from which failure
rates can be modified to account for differences in environment from the environments t...view more

IEC 60050-192:2015 gives the general terminology used in the field of dependability. The terms are generic and are applicable to all fields of dependability methodology, including electrotechnical applications. The document is not an exhaustive vocabulary for all IEC standards in the dependability field: definitions for some specialized terms may only be found in the relevant standards. This document replaces sections 1 to 20 of IEC 60050-191:1990, which has been subjected to a systematic, in-de...view more

This document provides requirements and guidance for obsolescence management applicable
to any organization that is dependent on another organization to obtain value from the
usefulness of the items that it provides. A cost-effective obsolescence management process
and the activities used to implement the process are applicable throughout all phases of an
item’s life cycle.
This document covers the following areas:
• establishing an obsolescence management policy;
• establishing an infras...view more

IEC TS 62998-1:2019 gives requirements for the development and integration of safety related sensors (SRS) and safety related sensor systems (SRSS) used for protection of persons with special attention to systematic capabilities.
This generic standard only applies if
– protection of persons is to be performed by using sensors, and
– standards for functional safety of electrical control systems address sensor(s) as subsystem or subsystem element, and
– product specific sensor standards (e.g. ...view more

This document explains how failure modes and effects analysis (FMEA), including the failure
modes, effects and criticality analysis (FMECA) variant, is planned, performed, documented
and maintained.
The purpose of failure modes and effects analysis (FMEA) is to establish how items or
processes might fail to perform their function so that any required treatments could be
identified. An FMEA provides a systematic method for identifying modes of failure together
with their effects on the item...view more

This document provides guidance in relation to a set of requirements placed upon system life
cycles in order for an open system to achieve open systems dependability.
This document elaborates on IEC 60300-1 by providing details of the changes needed to
accommodate the characteristics of open systems. It defines process views based on
ISO/IEC/IEEE 15288:2015, which identifies the set of system life cycle processes.
This document is applicable to life cycles of products, systems, processes or...view more

Obsolescence is a significant risk factor for an organisation and/or a programme activity regarding the continuity of productions, services and maintenance in operational conditions of equipments and systems. It can appear in any phase of the product life cycle. Thus it is essential that the organisation determines the best strategy to be implemented in order to control these risks, implying its customers and suppliers in the definition of this strategy.
This recommendation is a document meant ...view more
