It is the world's largest developer of spontaneous international standards and it makes the world trade easier by providing common standards among nations. Around twenty-two thousand standards have been set, casing everything from manufactured products and technology to food safety, agriculture, and healthcare.

Guidelines of  ISO certification are not directly enforced by law as it a non-government organization. However, many companies choose to go through the certification process of the International Organization for Standardization to ensure an efficient and reliable process that can be trusted by customers for quality, value, and reliability.

The process of ISO certification varies based on the standard being certified, and certification should be performed by an accredited certification body. When  discussing a certification the required guideline should be considered.

The ISO certification is highly regarded, as a company must participate in regular audits after initial certification to ensure that it continues to meet ISO standards and makes any necessary changes to address any relevant ISO updates in a timely manner. ISO certificates are valid for 3 years after they are issued, and a full recertification audit is required at the end of this 3 year time period to prevent the certification from lapsing.
