No. ISO doesn’t provide certification or conformity assessment

Certification is the provision by an independent body of written assurance (a certificate) that the product, service or system in question meets specific requirements. Certification is also known as third party conformity assessment.
Many companies and organizations decide to get certified to one of ISO’s management system standards, such as ISO 9001. This is a way of showing outsiders that the organisation has an effective quality management system in place..

Testing is the determination of one or more of an object or product’s characteristics and is usually performed by a laboratory. For example, many people have their blood tested which involves analysing the blood against a number of characteristics such as whether it shows the presence of a disease, or genetic disorder. CASCO has developed a number of standards that laboratories can follow to help ensure that their results can be trusted

Inspection describes the regular checking of a product to make sure it meets specified criteria. Fire extinguishers, for example, need regular inspections to ensure they are safe for use. CASCO has developed a number of standards that inspection bodies can follow to help ensure that we can trust their work.

The General Assembly is the ultimate authority of the Organization. It is composed of ISO members, and considers any matter submitted by the ISO Council. The proposals put to the General Assembly are developed by the Council, which is drawn from the ISO membership. The Council, which resembles the board of directors of a business organization, meets three times per year to discuss key matters relating to ISO strategy and policy, financial as well as operational and statutory matters. ISO Council membership rotates regularly to ensure that it is representative

Neither private individuals nor companies can join ISO as a member. Membership of ISO is only open to national standards institutes. In some cases, similar organizations, most representative of standardization in their country, have become members. It is worth noting that there is only ever one ISO member per country. It's worth bearing in mind that a company or organization that is certified to an ISO standard is not an ISO member.
