ISO 9000 variants

Answer:

I understand that by ISO 9000 variants you mean:

ISO 9000;
ISO 9001; and
ISO 9004

ISO 9000 is a standard about quality management fundamentals and vocabulary, it is not used in certification. Whoever uses ISO 9001 and has vocabulary issues can use it.

ISO 9001 is used in certification and specifies requirements for a quality management system. It can be used to certify any kind of organization because it is generic.

ISO 9004 is a standard that gives guidelines for enhancing an organization's ability to achieve sustained success, it is not used in certification.
