What is ISO, its most popular international standards, and more.
Published 28 Mar 2023
The International Organization for Standardization (ISO) is an independent non-government organization that establishes internationally recognized standards. ISO was founded in 1947 with the goal to set standards that will help set benchmarks for quality, safety, and processes across industries and regions. Originally formed in London by 65 delegates from 25 countries, ISO is now based in Geneva, Switzerland and has since published 22,782 international standards recognized by its members in 164 countries.
The International Organization for Standardization decided to use “ISO,” derived from the Greek isos which means equal, as its short-form regardless of the language or country where it is recognized.
Designed by ISO members, ISO standards provide frameworks, guidelines, or requirements that can be followed to help achieve their intended purpose. ISO standards aid multiple industries in different regions implement internationally recognized benchmarks for quality, security, safety, etc.
Contrary to popular belief, ISO itself does not provide certifications for the standards it publishes. It is the third-party auditors that conduct inspections and provide certifications for ISO standards. To be “certified” for an ISO standard means that an organization has provided enough proof to third-party auditors that they have met the requirements of said standard.
Today, ISO is considered the gold standard by many businesses and organizations around the globe. Aside from certification, adhering to ISO standards help in achieving the following:
There are several approaches to preparing for ISO certification, such as engaging with consultants to seek advice on certification or preparing internally before getting third-party help. Here are 5 steps to prepare for third-party certification of an ISO standard.
ISO certification is not a one-off endeavor and is valid only for three years starting from the date of certification. ISO certification is valid for three years, after which, recertification is needed to ensure consistency of ISO standard-aligned processes. Continue implementing the ISO-aligned processes and be aware of updates even after the certification for the ISO standard is achieved. ISO standards are reviewed every 5 years and revisions are published by ISO in order to reflect current industry best practices.
Eliminate manual tasks and streamline your operations.
Out of the 22,782 international standards, here are 9 of the most popular ISO standards and how they are commonly used.
ISO 9001:2015 – ISO’s most in demand international standard designed to set a framework for implementing Quality Management System (QMS) in any organization or industry. This standard, which belongs to the ISO 9000 series, served as a basis for other international standards such as ISO 13485:2016 and IATF 16949:2016, and is an optional prerequisite for other standards such as ISO 17025. The ISO 9001:2015 standard, although technically optional, has become a requirement by certain institutions in order to engage in business.

An ISO standard is created for a specific purpose or to address a certain need of an industry. Despite the unique intent for the development of each ISO standard, the most popular ISO standards do have some common sections. Below are the 10 most common sections found in most ISO standards:
This is a mandatory section that contains the description of the international standard’s scope and limitation, goal, the organization/s it is applicable to, and any special condition that needs special attention.
Another mandatory section for all ISO standards, it lists the document titles of any normative references. According to ISO, these are documents “which are cited in the text in such a way that some or all of their content constitutes requirements of the document.”
This mandatory section defines the terms used in the standard or references the title of the document that would contain these terms and definitions.
The context helps confirm if internal and external issues that can impact the goal of the standard had been determined. This section also seeks to confirm if the interested parties and the expectations that are relevant to the implementation of the standard are identified.
The leadership section stresses the responsibility of organizational leadership to spearhead the implementation of the ISO standard. It seeks to confirm the leadership’s commitment to continuously improve processes and allocate resources to support the implementation of the standard. Depending on the standard, worker participation and company culture is also taken into account.
This section is used to confirm if there are plans, procedures, objectives, and actions aligned with the intent to implement the standard. Depending on the standard, the planning section also seeks to determine if objectives are measurable or if risks and opportunities are taken into consideration.
The support section typically consists of clauses for employee awareness of the processes involved in the standard, documentation of employee competency, internal and external communications, and if sufficient resources and support that will help employees fulfill the requirements of the standard are available.
The operation section aims to confirm if the organization has properly planned, implemented, controlled, and maintained the processes needed to meet the requirements of the standard. This section also emphasizes the need for documentation to prove that the processes were indeed carried out according to plan. Depending on the standard, outsourced processes may also be taken into consideration.
The performance evaluation section tackles the need for the organization to determine monitoring and performance evaluation protocols that ensure valid results. This includes confirmation that the frequency of evaluations, what needs to be measured, method of analysis, and the persons responsible for the tasks had been established. Documentation of performance evaluation is also highlighted in this section.
Crucial for ISO standards, particularly those intended for management system standards, the improvement section aims to lay down the framework for the promotion of continuous process improvement. Even those standards that do not have this section still stress on the commitment to incorporate processes for continuous improvement.
Around the world, over a million organizations are certified for at least one of the international standards set by ISO. Some of the standards developed by ISO even became the basis or were expanded upon by other recognized organizations that also publish international standards. Since ISO’s inception more than 70 years ago, it has helped organizations implement processes, create products, develop industry best practices, foster international partnerships, and improve industry benchmarks that align with ISO standards and will continue to do so in the foreseeable future.
