What is ISO and why are there so many of them?

ISO stands for "International Organization for Standardization." It is a non-profit international organization that develops and publishes international standards for various fields and industries.

The goal of ISO is to harmonize standards and practices, facilitating international trade and interoperability. It also ensures the quality, safety, and efficiency of products and services.

There are many different types of normative documents issued by ISO covering a wide range of areas. These standards serve various purposes and applications.

  • Management standards: These include standards related to management systems, such as ISO 9001 for quality management and ISO 14001 for environmental management.
  • Technical standards: These deal with technical specifications and requirements for products, processes, and services. For example, ISO 3166 defines country codes and their subdivisions.
  • Industry-specific standards: ISO issues standards for specific industries, such as healthcare (ISO 13485), the automotive industry (ISO/TS 16949), and many others.
  • Information technology standards: ISO has standards related to information technologies and information security, such as ISO 27001 for information security management.

Why are there so many different types of standards?

Because different industries and areas have different needs and requirements for standardization. Standards are created by experts and industry representatives in line with the specific needs of a particular industry. This allows for the creation of standards that are relevant and useful for specific areas and applications.
