Due to big importance, reliability issues are covered by many standards, which provide well-tested procedures and design values. The standards are the result of cooperation of many experts from various countries and contribute worldwide to the high level of quality, reliability, and safety of products and services and to the reduction of failures and accidents. Standards also facilitate legal disputes related to the compensation of various damages. In some cases, the use of standards is compulsory, but sometimes it is a matter of agreement between the supplier and the customer. However, competition among many manufacturers leads to high emphasis on quality and reliability so that the use of pertinent standards gradually becomes the norm. Generally, standards offer safe rules and values, though somewhat conservative, so that they are also updated from time to time, with respect to new information or methods.

There are many associations for standardization around the world. The names of many of them as well as the numbers and titles of numerous individual standards can be found, for example, at the website of IHS Global ( and can be purchased here. They can also be found (and bought) via various standardization bodies given below. In this chapter, several institutions will be listed, whose standards for reliability are used internationally. Then, some of these standards will be named as examples.

1. IEC — International Electrotechnical Commission (

The technical commission TC 56 “Dependability” of this organization for standardization prepares the international standards related to reliability. An overview of all valid IEC standards can be found via the above web site.


2. ISO — International Commission for Standardisation (

This commission prepares and approves the standards for quality and many other subjects.

Reliability and quality standards can also be found under BS (British Standards), DIN (Deutsches Institut für Normung), ASME (American Society of Mechanical Engineers), NBS (National Bureau of Standards, USA), JSA (Japanese Standards Association), KSA (Korean Standards Association), GOST (Gosudarstvennye Standarty — Russian state standards), and various others. Standards for civil engineering constructions can be found, for example, under EN (Euronorms, i.e. European standards or Eurocodes; see

Standards for military applications, but not only for them, can be found via (United Kingdom defence standards), (NATO Standardization Office), and (DoD or U.S. Department of Defense) or via websites such as,, or The access to some of them is open only for authorized people.

ISO 9000. Quality management.

This is a group of standards that addresses various aspects of quality management. It provides guidance and tools for companies and organizations that want to ensure that their products and services consistently meet the customer’s requirements and that quality is permanently improved.

The updated version ISO 9001:2008 – Quality Management Systems has several parts: Principles, Vocabulary, Requirements, etc. This standard sets out the criteria for a quality management system and is the only standard in this family that can be certified to. It can be used by any organization regardless of its field of activity. ISO 9001:2008 is implemented by more than 1 million companies and organizations in more than 170 countries.

There are also branch-related groups of standards based on internationally recognized standard ISO 9001. For example, standards AS/EN 9100, AS/EN 9110, and AS/EN 9120 are devoted to quality management systems with specific requirements on aviation, space, and defense industries. They are published by the International Aerospace Quality Group (IAQG). Especially, the AS/EN 9120 focuses on product safety and reliability and addresses critical product performance, conformity to specifications, and airworthiness.

EN 50126. Railway applications. The Specification and Demonstration of Reliability, Availability, Maintainability and Safety (RAMS). This is a group of the standards of the CENELEC (European Committee for Electrotechnical Standardization) for the reliability and safety in rail industry in Europe and other countries. It has several parts: EN 50126-1: Part 1: Generic RAMS process, EN 50126-2: Part 2: Systems approach to safety, EN 50126-3: Guide to application of EN 50126-1 for rolling stock RAM, EN 50126-4: Functional safety: Electrical/electronic/programmable electronic systems, and EN 50126-5: Functional safety: Software.

The standards for reliability and quality in the railway industry can also be found under the International Railway Industry Standard (IRIS). Those for road vehicles industry can be found, for example, under SAE (Society of Automotive Engineers) or VDI (Verein Deutscher Ingenieure).

As said above, the standards are updated from time to time, and some can even lose its validity, be withdrawn, or replaced by others. Thus, when looking for a certain standard, one must make sure whether it is valid or if it has undergone some changes.



Various volumes of Military Handbook (MIL-HDBK) or Military Standards (MIL-STD), issued by the U.S. Department of Defense (DoD), deal with reliability (among other things) and are worldwide recognized and become international standards of their own. Some titles follow. However, the reader must always check whether the pertinent issue is valid. Nevertheless, even “cancelled” issues can contain useful information.
