Standards have existed since the beginning of recorded history. Early examples are the creation of the calendar and the ell, which was a standardized unit for measuring equivalent to the length of King Henry I’s arm. Standards have emerged and evolved over time due to laws, regulations, safety, and the general needs of the advancement of society.

What are Standards?

“Standards are nothing more, and nothing less, than doing things a consistent way.” Standards provide guidelines and an approach to take for reaching a desired goal. They may also be thought of as high level requirements. Standards apply throughout most/all industries. ISO, International Organization for Standardization, identifes that "a standard is a document that provides requirements, specifications, guidelines or characteristics that can be used consistently to ensure that materials, products, processes and services are fit for their purpose" ( The focus of this module is the standards used in Aerospace Industry.


The Importance and Implications of Standards

Standards are used to ensure that products are made reliably, are repeatable, and adhere to safety laws and regulations. They provide awareness to groups on the same focus and interests.  Standards may be used to more definitively quantify best practices amongst common industries.

Standards are important because they provide a basis of what to expect out of a product or service. Implications to not having or not following standards can range from inconveniences to major human safety related issues. Not adhering to standards may also involve legal implications.

If certain standards did not exist, for example, USB flash drives would not be universal; car manufacturers may swap the gas and break pedals; only certain light bulbs would fit certain sockets; payload quality would vary tremendously.


Standards for Quality Management in the Aerospace Industry


There are many different, comprehensive, and sophisticated standards used in Aerospace Industry. While some of them are about management systems standards such as ISO 9000 and AS 9100, others are related to processes, components, inputs, or outcomes in the industry. This module will focus on those standards.
