What are the Differences Between ISO9001 and AS9100?

March 27 2020

Quality assurance and certifications are one of the many benefits we provide our customers.

Spend enough time around ECMs and you are sure to see terms like ISO9001 or AS9100 pop up. ECMs that have earned those certifications follow rigorous standards for quality, but you may have wondered what those certifications stand for, and why it matters.

ISO9001 and AS9100 tell you a lot about the ECM you are considering partnering with. Simply put, it's a mark of a company that has put customer service and excellence in manufacturing at the forefront of their business. Both certifications mean different things to different sectors, but the bottom line is that they have achieved a level of service, quality, and production that puts them above others in the industry.

Electronics Manufacturing Companies: What Services Do They Provide


While each electronic manufacturer may choose to run their business and manufacture how they choose, manufacturers in certain industries understand the benefits of adopting certain levels of standardization for their customers and their business.

ECMs have adopted standardization in regards to electronic manufacturing, and those standards are recognized worldwide. Standardization is a great benefit to customers, as they know certain quality standards are going to be honored across the board.

This is where ISO9001 comes into play. Stated simply, ISO9001 is basically a less stringent form of AS9100. Set by the International Standards Organization, the ISO9001 standard gives customers a guarantee of what they can expect from a certified ECM.

In ISO's own words, the ISO9001 standard ensures "strong customer focus, motivation and implication of top management, process approach and continual improvement." The standards are constantly updated, and manufacturers must continue to comply to maintain certification.

Levison Enterprises offers more than electronic assembly. We also offer electronic design, custom prototype, PCBA manufacture and PCB assembly


The AS9100 standard is similar to the ISO9001 standard, except it is concerned only with the challenges of manufacturing for aviation, space, and defense manufacturers.

Because it is related to one specific sector, the AS9100 certification is usually only adopted by companies that manufacture aircraft components and materials, or design aerospace parts and assemblies, or by companies that oversee quality management of companies in those fields. Just like the ISO9001 standards, AS9100 is continually updated in relation to the best practices in the industry.

AS9100 standards most importantly reinforce traceability through the supply chain, ensuring that counterfeit or low-quality parts do not make their way into the manufacturing process. It also instills confidence with the company. Holding this certification is evidence of a commitment to conserving time, money, and resources in the pursuit of operational efficiency.

As a leader in the aerospace and defense industry, Levison Enterprises is proud of its ability to meet and exceed the standards laid out by both ISO9001 and AS9100. For our experienced team of professionals, it's a mark of pride that we do things the right way.
