What is ISO?
ISO is the abbreviation for the International Organization for Standardization, which is an independent international NGO that globally sets recognized standards for a range of principles for a given process to ensure uniform and high quality.

ISO is the designation for internationally recognized standards that contribute to a uniform way of viewing and acting on everything from processes, quality, safety, health to technologies and digital devices in a wide range of areas.
ISO has existed since 1946
ISO stands for International Organization for Standardization, which is an independent NGO (non-governmental organization) that was established in 1946 shortly after the end of World War II. Its predecessor was called ISA (International Federation of the National Standardizing Associations), which was suspended during World War II in 1942. After the war, the newly established UN body UNSCC (United Nations Standards Coordinating Committee) approached ISA to establish a new international standard.
The abbreviation ISO does not match the full name, which is because it is abbreviated depending on the different languages of the member countries. The founders of the organization chose ISO as a common designation across languages, which was reportedly chosen as a derivative of the Greek word “isos,” meaning equal or equality.
ISO has 25,000 international standards and 171 member countries
As of 2024, ISO has published more than 25,000 standards, covering standards in virtually all conceivable areas from product manufacturing, technologies, and food safety to transport, IT, and sustainability, and much more.
In total, 171 countries are represented and recognize ISO standards. In addition, there are so-called corresponding and subscribing member countries. In Denmark, ISO is represented by Dansk Standard, which exclusively approves the international ISO standards for implementation in Danish standards.

Companies are endorsed as safe and quality-conscious with ISO
In recent times, ISO has become synonymous with an endorsed recognition of a company’s ability to comply with and maintain principles in operations that, for example, ensure high and consistent quality, recognize environmentally friendly initiatives, or ensure a healthy and safe working environment.
When a company is certified, it is often a signal to customers, suppliers, and other partners that the company acts responsibly in a number of areas. At the same time, the trend is that companies increasingly want their suppliers and partners to work according to the same principles.
