AS9100 vs. ISO9001: Which one is better?


Quality is a crucial part of almost every business but these measures become even more essential when it comes to the aerospace sector and defense sectors. When quality management is not done right in either the defense or aerospace sector many lives can be at stake.

Understanding the importance of quality management is very important in any organization because it is linked to almost every aspect of the company. From manufacturing to delivering products successfully to the customers quality management plays a role at every level. To maintain this quality in any organization two standards are known worldwide ISO9001 and AS9100. In this blog, the differences between these standards are explored which can help you identify which standard can work best for you.


What is AS9100?

AS9100 is a quality standard that is specially designed to fulfill the quality requirements of the aerospace sector and it is often referred to as the extension of the ISO9001 standard. This standard is supposed to be enhanced in comparison to ISO9001 and is based on the objective of ensuring, that services and products in the aerospace industry meet the highest quality standards. 


What is ISO9001?

ISO9001 is a globally known standard when it comes to managing quality in any organization. This standard is not industry-specific but is applicable to every industry and includes a framework to enhance the overall quality. This standard is also considered as the fundamental requirement of quality and principles in this standard are focused on the requirements of customers and motivate management. The goal of this standard is to make sure customers get the best quality services and products and by doing so, it benefits the businesses. Companies can become ISO Certificate Training Services after detailed training and passing the audit. 


Now let’s focus on their differences based on the following measures:


Industry focus

AS9100 is industry-specific and is designed to meet the requirements of the aerospace sector only. Whereas, ISO9001 is designed to meet the requirements of every industry and work as a general standard to maintain quality. 



When it comes to implementing AS9100 in the aerospace industry, requires detailed quality control measures to ensure the levels of safety and production quality. Whereas, ISO9001 is a general framework that is required to be implemented and is based on less specific requirements when it comes to a specific industry.


Regulatory compliance

AS9100 is based on international regulations and standards such as based on the regulations of the EASA European Union Aviation Safety Agency. On the other hand, ISO9001 does not have specific reference to the regulations which makes it less specific.


Risk management

Risk management for the AS9100 is tailored and considered strictly to meet the requirements of the aerospace sector. On the other hand, ISO9001 promotes risk-based thinking that is not industry-specific but based on the overall guidelines and scenarios.


Product Safety

AS9100 has a strong impact on product safety based on the sensitive nature of the aviation sector and requirements. Whereas ISO9001 is all about the organizational measures and requirements but is quite general when it comes to the safety of the products. 


Managing suppliers

AS9100 pays huge attention to supplier management and focuses on the quality of the materials to ensure the safety of the aerospace sector. On the other hand, ISO9001 offers a huge set of guidelines that can help with evaluating suppliers in any industry.


Both are related

It is already mentioned above that AS9100 is derived from the ISO9001 which means that every clause in the ISO9001 is followed in the AS9100 which makes both standards quite identical but still, there are some differences that are discussed above. ISO is known as the base standard and it provides a direction for the organizations to refine their methods of delivering quality to their customers. 


Both standards are based on the following measures inside the organization when it comes to delivering quality.


Prioritize customers

Identification of the requirements of the customers is considered the most important part of the quality standards because, in the end, every organization needs to satisfy its customers. 


Organizational leadership

Maintaining strong leadership in an organization is an effective way to balance and manage quality in any organization. 



Employees are the backbone of any business, training them and engaging them at every level is the top priority of every quality standard either ISO9001 or AS9100. 


Process approach

Defining clear processes can lead to improved quality in any business sector. 


Continuous improvement

Quality standards aim to bring improvement continuously so that organizations become able to maintain their position in the fast-growing market, especially when it comes to the aerospace sector. 


Decision making

Quality standards focus on the collection and analysis of the data which can be an effective way to promote correct decision making and can help with mitigating risks. 


Supplier management

Analyzing and managing suppliers can have a huge impact on quality because it can also lead to better cost management. 



This article has discussed both standards along with their differences and their requirements. It can be concluded that both standards are essential when it comes to managing quality in an organization. 


AS9100 is an industry-specific standard that is specially designed to fulfill the requirements of aerospace and defense companies because of their specific needs and sensitive nature. 


Whereas, the ISO9001 standard is a universal quality standard that can be applied in any industry and can meet the quality requirements of the sector. Understanding the differences between both standards can be helpful for you because it can help you choose intelligently. AS9100 can also be tailored to meet your organization’s specific needs so, choose wisely and meet the quality requirements of your business.
